m4 profile barrel vs government profile

That’s why a lighter barrel might cost more than a heavier one — you’re not buying steel by the pound. Both test consisted of one 10 shot group? A cooler barrel expands less, and it remains more accurate. Both of these SOCOM barrels have the “O” stamp near the chamber portion of the barrel, indicating the barrel has a chrome-lined chamber and bore. Molon, good to see you back up on the net. After the gas port it gets heavier, out to the muzzle. All of the M4 family of rifles have a 14.5 inch barrel length with a carbine length gas port system. some say that the m4 cuts mess with barrel harmonics...Shrug, I don't know, i haven't tested this assertion myself. The rest of the series can be found at the links below: Part 1: Intro, Fundamentals, and Manufacturing of AR Barrels When it is used, the light barrel will probably easily handle as much ammo as you can comfortably carry. The ELW barrel is available with fluting as an option for further lightening. While they’re generally considered pretty heavy to pack around in the field (military, hunt, or even 3-gun), they’re great for bench target shooting and long distance precision shooting. Colt no longer stamps an “F” on their front sight bases, but their newer front sight bases maintain the length of 1.98” from the top of the barrel to the shelf for the front sight post. The M4 barrel is lightweight under the handguards, until just before the gas port. Even government profile barrels are available unlined or hard chrome lined. See the advantages of BCM Enhanced Profile Barrels. A genuine Colt M4A1 SOCOM barrel is 14.5” long and has a. This leads to decorative embellishments like spiral fluting, or, further yet, diamond fluting, created by cutting spiral flutes first clockwise around the barrel, then counterclockwise. We’re going to get into AR-15 barrel profiles. But first, some notes from your physics class: 1) Heat is the enemy of accuracy. I've never had any rifle string on me (even my FAL). Remember, 4 minutes of angle at 100 yards is about 4 inches, and most combat shooting has been done at ranges shorter than 100 yards. The one big drawback to pinned and welded flash-hiders is that you're basically stuck with that configuration once it's pinned and welded. All their barrels are made in-house from “cradle to grave.” Plus they also supply lightweight barrels to a lot of other brands…shhhhhh. What matters is the distance from the mass to the force applying the rotation – which can be measured in foot-pounds, a measure of torque, or twisting force. Your email address will not be published.

Click here to snag a copy. “Varmint” isn’t a specific profile; it’s more of a type of shooting. Fluted barrels are simple in concept, but seem to be the source of a lot of misunderstanding and controversy. 2) The quick handling of single-point slings has made them the popular style on patrol in combat zones these days. To demonstrate a variety of options, we obtained four identical standard 16-inch mid-length gas system barrels with government profiles (and 0.750-inch gas block) from Bravo Company USA. You are using an out of date browser. Does your original barrel still shoot pretty well after all this time? These are usually 18 and 20 inches respectively, and made of 416 stainless steel. Take note that on page 2 he compares the SOCOM to two 16 inch m4 profile barrels which he noted performed basically the same as their 14.5 inch counterparts. On the other hand, fluting can relieve manufacturing stresses in the steel. This makes an elegant and beautiful solution to optimizing the barrel; it’s a pity that most of it will be covered by a handguard. All of Del-Ton’s 16-inch AR barrel options use a mid-length gas system and are chambered to 5.56 NATO. Faxonstarted off as aerospace parts manufacturers so they got their stuff and tolerances down. Our flagship AR15 M4 M16 barrels and the pride of our AR offerings are our Chrome Lined military clone barrels; these barrels feature a M4 contour, 1:7 twist rate, M4 barrel extension, 1/2x28 muzzle threading and are … 3) Not physics but economics: When a manufacturer starts with a barrel “blank” and turns it to a specified profile on a lathe, removing more metal = more time and tooling = higher cost to you, the buyer. Sniper’s Hide is a community of Snipers of all kinds, focusing on long range shooting, accuracy, and ballistics. The USGI barrel profiles (often referred to as the Government Profile) enable the operator to carry their weapon for longer periods of time and deploy them faster than the heavier commercial H-Barrel counterparts. The Navy Recce rifles have used barrels by premium custom makers like Krieger and Lilja, though other makers offer similar profiles to civilians under the Recce name. The date-code on my original SOCOM barrel was “11/03” and the date-code on my newer SOCOM barrel is “02/18”. I have read all of your stuff; very informative. Great article. Of course, that same moment of inertia will also stabilize the rifle a little better when it’s time to squeeze the trigger. In summary: Lighter barrels are less fatiguing to carry; longer barrels are good for long-range shooting, and heavy barrels are best for bench shooting or extremely long range. The next pic is a close-up comparing the two barrels in the area between the chamber and the gas block journal, showing you were the extra weight is added. Once relaxed into the sling, the shooter adjusts his body until the rifle is on target. Thanks! In a survival scenario it’s more likely that your rifle will spend most of its time slung on your back, where the lighter weapon will produce less fatigue, and will be used only occasionally. For a better experience, please enable JavaScript in your browser before proceeding. Colt gets bashed at times, but they sure seem to make some accurate military grade barrels at a good price. Besides the A1 “pencil” and A2 barrel profiles, there are two more recent significant developments: The “S2W” (strength-to-weight [ratio]) barrel, a CHF barrel by Daniel Defense, sold with a chromed bore, and the “ELW” (enhanced lightweight) profile from Bravo Company Mfg. This profile is now commonly called “A2”. You can’t achieve either of those things by removing material. A genuine SOCOM barrel has the typical M4 circumferential cut-out located approximately 1.4” forward of the gas block for the attachment of an M203, as well as rectangular shaped cut-outs underneath the hand-guards on the port and starboard sides of the barrel, located approximately 1.4” aft of the gas block, for the same reason. The additional weight really doesn’t do much as a heat sink, since most of the pressure and heat is before the gas block, but it does help a little to stabilize the rifle for offhand shooting. Of course, the more rigid barrels resist “whip” far better than the slim lightweight barrels, another reason to choose them when high accuracy is your main criterion. 14.5″ Pencil Barrel with Attached Muzzle [Review] Bu… Just what I needed! Ya don't need a M4, unless you have an old fashioned grenade launcher. Fluting increases cooling surface area, but also removes thermal mass, so the cooling gains are at least partly offset by lost thermal mass. In 2010, my original SOCOM barrel with the “11/03” date-code produced a 10-shot group fired from a distance of 100 yards that had an extreme spread of 0.90”. The most popular barrel profile now is the M4 style, sometimes a direct copy of the 14.5″ military M4 barrel, but more often slightly extended to 16″ for legal civilian use. I’ve reviewed several of their barrels over the years and really like their stuff for the price point. The extra thickness near the muzzle has no measurable difference in accuracy, even in rapid fire. What you can do is improve the ratio of strength to weight by carefully removing material in selected areas. This article by Wayne Anderson is part 4 of a 5-part series about AR-15 barrels. profile. The idea is long-range accuracy rather than a combat rifle. I could never understand why so many people offer M4 barrels as a selling point, especially when they're 16" and made of the incorrect steel.

Some will tell you it improves barrel cooling. If you’re going to be carrying a rifle for extended periods, lightweight barrels can be your friend. After the gas port it gets heavier, out to the muzzle. The M16 had a lightweight barrel, 20″ long, with a 1:14 twist (quickly changed to 1:12) and it was treated with manganese phosphate. Beyond these come the true heavyweights – the HBAR (heavy barrel) and the even heavier bull barrel profiles. Barrel has 5.56 Nato chamber, 1/7 twist rate, M4 barrel extension, rifle length gas system, threaded ½ x 28 muzzle and Mil-Spec phosphate coated. A heavier barrel contains a lot more thermal mass, which means the heat can be spread into more steel, heating the barrel less overall. Their data showed that the M4 profile barrel actually outlasted the others. Part 2: Barrel Length, Gas Systems, and Rifling This allows it to be slotted into an M4 chassis without issue and either a gunsmith or your own hands can handle the installation, provided that you have the right tools. Next we find a profile often called “Recce” (military slang for “reconnaissance”). AR-15 Barrel Profile: A2 Government vs M4 style?

(Gov is M4 in the carbine) In a carbine with an M4 profile barrel it will either be 14.5 or 16 inches long, lightweight under the handguards, and there will be a notch cut into the barrel forward of the front sight for mounting a grenade launcher. The shooter’s forward (usually left) arm is placed through the loop and it’s pulled tight around the biceps area. 16" 5.56 / .223 ar-15 1x7 ballistic advantage m4 profile carbine length barrel - modern babl556014m retail: $160.00. The military standard is 4 MOA, and that’s pretty much good enough to hit a man-sized target at 100 yards if you take the time to aim properly. Does your original barrel still shoot pretty well after all this time? The Recce barrel is stainless, generally 16″ long with a mid-length gas system, and heavy under the handguard, where the extra weight does provide useful thermal mass. Molon you're a wealth of knowledge and brought the understanding of accuracy on Arfcom up about 10,000 degrees. In the beginning, Eugene Stoner created the AR, which was upgraded to selective fire and named the M16 by the US Government. This barrel is also offered with straight flutes, which begin near the chamber, cut deep, but as the profile tapers the flutes become shallower until they end entirely. There is also the “Government” profile found on the M16A2, M4 carbine, and many civilian rifles. These barrels are meaty, big cylinders of steel devoid of any lightening in their profiles. Colt M4A1 SOCOM Barrel Accuracy: Another Look. AR-15.223 Wydle Government Barrel Heavy - Heavy barrels are thick from one end to the other and are, of course, literally heavy. I learned so much on the type of barrel I’m looking for to upgrade my AR platform . So not all flutes are created equal – shallow ones retain more strength, deeper ones help with cooling. This is important for precision shooting – but less important for short-range or casual gunnery. There’s one more point of fluting worth mentioning: Bravo Company’s ELW (enhanced lightweight) barrel begins with a gracefully tapered profile, which allocates mass and strength along the barrel’s axis appropriate to the pressure loads. It’s been said that dimpling produces better thermal efficiency in shedding heat; of course, that would also depend on depth and surface area. Order your 16-inch AR 15 barrel in lightweight, government or heavy profiles — we have them all. As a side note, the pic below shows what a great job Ken Elmore of Specialized Armament does on his pin and weld jobs. Required fields are marked *.

The theory is that you’re shooting prairie dogs and coyotes on your ranch (or similar shooting), or informal competition. This group was fired off of sand-bags using match-grade hand-loads and a high magnification scope. Choose an AR 15 5.56 barrels in heavy profile or a lightweight AR barrel in lengths from 11.5 to 20 inches. A fatigued gunner is a less accurate and less useful gunner. The stripped weight of the SOCOM barrel is 5 ounces heavier than the stripped weight of the standard Colt 14.5” M4 barrel. 1. Similar mission demands have otherwise made these very similar. It’s also worth noting that the profiles listed above aren’t the only ones available in AR barrels, just the most commonly available ones, and within those descriptions some include a number of variations. It's finished in black nitride for a long lasting, performance product. 2) Weight can be your enemy or your friend, and where the weight is located matters.

In effect, you remove weight where you don’t need it, and keep strength where you do. A Colt Socom barrel tested by Molon was capable of producing an 30 round average sub-MOA load with an extreme spread of .9 inches and a mean radius of .35. weapon of choice, imagining pouring magazine after magazine of destruction on advancing waves of ravening Nazi Klingon zombies. {"cart_token":"","hash":"","cart_data":""}, AR-15 Barrels: Caliber, Chamber, & the Best Steel Type for Your AR Barrel (Part 3), AR-15 Barrels – Surface Treatments & Muzzle Types (Part 5), AR15 Barrels: Profiles, Fluting, and Dimpling (Part 4). blakeforeal New Member. At the request of the Marines the M16A2 was given a chromed bore and a heavier barrel profile forward of the gas block, mainly to minimize the chance of bending (one of the A1’s most common failures in close combat). Shooting a rifle generates a great deal of heat, and the barrel absorbs a lot of it. Thanks so much. -Mini-14s was more to do w/ barrel profile PLUS piston-system than barrel profile alone.-Anon at 5/13 #s and effects regarding M855 vs M193 are spot on.-Sling bending 20″ pencil barrel and affecting POI is real — and the same bend applies to gov’t profile barrels … The result is that, when done right, a fluted barrel will be stronger in certain areas, and more rigid in certain axes, than an unfluted barrel of the same weight. We have AR15 and M4 MELONITE barrels including pencil profile barrels, mid-length barrels, carbine barrels and pistol barrels for the .223 cartridge and the 5.56 NATO cartridge.

News, special offers, exclusive discounts, and more! Barrel and chamber are chrome lined to a specification that is almost double the thickness of a standard M4/M16 Mil-Spec barrel and are stamped with the FN oval The design is a compromise between weight for carrying and handling and muzzle velocity and heat absorption to optimize accuracy. 4 0 0. But… how many magazines are they planning to carry? Yes, lightweight barrels heat up faster, and the groups will open up, but usually we’re talking about a change on the order of 1.5-2 MOA accuracy opening up to 3 or maybe 4 MOA. Discussion in 'AR-15 Discussion' started by blakeforeal, Oct 7, 2014. AR barrels can be fluted before or after the gas block, but the gas port area itself is never fluted, due to the need for a full diameter at that point.

The solution is to free float the barrel, and mount the sling to the free float tube, leaving the barrel untouched. The SOCOM barrel has a stripped weight of 1 pound, 14 ounces. Another profile very much like the M4 is called the “government” profile: Basically the same, but without the M4 cut. It may not display this or other websites correctly. In this article, we will cover the different AR 15 Barrel Profiles and understand the importance of fluting and dimpling in AR 15 barrels. Unfortunately, I no longer own that barrel. On an assembled URG (upper receiver group), the M4 barrel is identifiable by the “M4 cut” – and here we’re not talking about feed ramps, but rather a narrower “notch” in the barrel, forward of the gas block, used to mount the M203 grenade launcher. A2 style muzzle brake. Hey guys! Some people will tell you it’s significant, others will say the additional cooling is almost too little to measure. Honestly looking for some opinions. We carry QPQ treated barrels, Nitride Barrels and standard mil spec chrome lined barrels. My original SOCOM barrel hand an “F-marked” front sight base. For point shooting, this is a significant advantage. The bore was not chromed. They offer enough thermal mass to absorb a lot of shooting and remain rigid and accurate for a long time. Barrel life was something in excess of 9,000 rounds (keep in mind that's a 1:7 twist, shooting full auto=lots of heat buildup). Your articles are always much appreciated. ... A selection Daniel Defense M4 AR15 Barrels demonstrating the Government profile.

Anderson.300 Blackout AR-15 M4 Profile Barrel Government Cut - Same as the M4, but lacks the grenade launcher cut. As it heats, steel expands minutely, and groups on target can expand measurably. But there’s another way to get lightened weight without much flexion, and that’s fluting, which we’ll discuss in a moment. 1) We didn’t mention barrel “whip”; a term you’ll hear sometimes to describe barrel flexion while shooting, which obviously affects the point of impact. That is only 2 ounces heavier than the ubiquitous 16” government profile barrel found on the Colt 6920. A 16" mid-length gas barrel has the proper spacing to mount a bayonet. As a special offer for our readers, you can get the Official US Army Manual for AR-15/M4/M16 right now – for free. In Barrett’s defense, they didn’t sell it that way; it was fluted by an aftermarket gunsmith.). The government profile barrel is also compatible with the current M203 mounting systems. There’s a reason most service personnel opt for the light M4 for general patrol work. If a barrel contains unresolved stresses from manufacturing it can expand unevenly or warp, which also affects point of impact (POI) as well as group size. We sent three of them to Adco Firearms to be dimpled, fluted and turned down to a lightweight contour. Varmint rifles tend to use very heavy barrels, usually 20-24″ long, and are generally made in stainless steel with a target crown. There is no benefit for an AR-15 to have an M4 profile barrel aside from historical accuracy (but even then, it needs to be a 14.5" barrel). Part 5: Surface Treatments and Muzzle Types. The gas port on a genuine SOCOM barrel has a diameter of 0.062” and the barrel employs a carbine-length gas system. Very informative, thanks for the great article. SOCOM vs. Standard M4 gov profile barrel. APOC Armory. What heat they do absorb affects them less, enabling them to remain acceptably accurate at extended ranges. Chambered in 5.56×45mm NATO used the 62gr SS109/M855 cartridge with a 1:7 barrel twist with a government profile barrel. You want this barrel, really, if you want a barrel that you can take anywhere, this is the one. The M4 barrel is lightweight under the handguards, until just before the gas port. This new build features a Colt cage-code marked M4 upper receiver, a Colt “C” marked bolt carrier group and a 13” Geissele MK14 M-LOK free-float hand-guard. That group was fired from my bench-rest set-up using match-grade hand-loads and a high magnification scope. The fact is that a great deal depends on the depth and width of the flutes, since deeper flutes create more surface area. Let’s wrap up this section with a couple of practical thoughts on barrel profiles. 16″ Pencil Barrel [Review] 2. (There’s a photo circulating of a fluted Barrett .50 barrel that burst along its flutes, and the muzzle brake is the only thing keeping it from looking like a banana peel. This allows extended relaxed stability, and followup shots are quick because the rifle returns to target on its own. The 20" barrel gives you 5.5" more sight radius (14.5" vs 20"), which is a 40% increase. The rest of the sling, still connected to the forend of the rifle, is shortened until it applies tension between arm and rifle when the shooter relaxes. If there’s anyone that knows the AR-15 platform, it’s the US military. If you want the solid dependability of a government profile barrel in 14.5 or 10.5-inch lengths, we have them too. The Government profile was an attempt to prevent the barrel from bending when used with a bayonet. Part 3: Caliber, Chamber, and Steel Types Moving toward heavier profiles, we come back to the Special Purpose Rifle (SPR) and Designated Marksman Rifle (DMR) barrels we discussed earlier. Choose barrel-only options, or have yours shipped with a barrel nut, front site base and a round handguard cap. This has a skinny profile near the receiver and a thicker profile towards the muzzle. So I am currently on the market for a barrel to finish up my first AR build and I am torn between the SOCOM and Standard M4 gov profile barrels.

FN Manufacturing 20 Inch Government Profile ( A2 ) Hammer Forged barrel. AR-15, M16, M4, 11.5",BCM Enhance Profile Barrels. Your email address will not be published. Fluting also increases the barrel’s surface area, which means that there’s more exposure to cooling air – in effect, the sides of the flutes act a little like cooling fins. Everyone agrees that it makes them lighter. So any part that’s narrower than that means more time on the lathe. This 10.5" barrel chambered in 9MM has a beautiful government profile and is milled from 4150 Chrome Moly Vanadium Steel. Two pounds at the end of a 1-foot bar exert the same 2 foot-pounds as one pound at the end of a two-foot bar. There’s another thing to think about — the barrel’s mass acts as a heat sink. The problem, if there is one, is that a sling mount on the barrel (such as under a front sight base) applies that tension directly to the barrel when used this way, potentially creating a bit of “whip” and shifting the point of impact. We’ll start this Daniel Defense DDM4V7 LW review by stating that this rifle is available in a couple of different finishes as well as a couple of different barrel profiles. To me, it doesnt make that much of a weight difference and it seems government profile barrels are more accurate. If the hordes of zombies are so close that you’re dumping magazines at them, an increase from 2 to 3 MOA accuracy won’t substantially affect your hits, and you’d be far better off taking carefully placed head shots anyway. These barrels are heavier under the handguard and taper only minutely toward the muzzle, and that mass makes them both heat and cool more slowly. The gas port on a genuine SOCOM barrel has a diameter of 0.062” and the barrel employs a carbine-length gas system. The most popular barrel profile now is the M4 style, sometimes a direct copy of the 14.5″ military M4 barrel, but more often slightly extended to 16″ for legal civilian use. Great article on AR-Barrels. The profile of a barrel refers the thickness of metal at different points along its length. From the gas block journal forward, the two barrels are identical, SOCOM barrel on top, standard barrel on bottom. What’s important here is called “moment of inertia,” which is how a physicist says that it’s easier to rotate a 10 pound dumbbell in your hand than a 10 pound barbell. A nice and tidy overview of AR barrels, and without a lot of nonsense. Some people like flutes because they look cool. For those complaining about weight, an M16A1 profile 20" barrel weighs almost exactly the same as a 16" M4 profile barrel. Barrel Contours: Tale of the Tape.

There are other options available too, not from double star, but you might consider lightweight, or gov. In 2010, I posted one of the first publicly available, in-depth. DS Arms manufactures our AR15 M4 M16 barrels from the premium 4150-11595E steel in a number of different barrel length, profiles and configurations. M4 pertains to carbine only but "Government" profile pertains to the M4 and the M16. The pic below shows the difference between the standard M4 barrel and the SOCOM barrel. This profile uses a 1:8 twist to allow 77-grain rounds, and was designed at the request of Navy SEALs who found the 18″ SPR barrel too long for their purposes but still needed a high precision (sub-MOA) combat rifle. The lightweight barrel profiles discussed above were usually designed for the common infantryman, shooting at relatively short ranges, and intended to deal reasonably well with rapid fire. This matters when you remember that any barrel, no matter how slim, has to start with a blank at least the diameter of the gas block – usually either .625″ or .750″. The main categories, however, are the so-called government profile (standard) and then the lightweight version. But some shooters fall back on an older configuration, known to military shooters as the 1907 style sling, when precise long-range shooting is called for.
