My grandfather was a Green Beret and A-Camp Team Leader within miles of both the DMZ and Laos, near Khe Sanh… Combat disabled before John Wayne’s movie ever hit theaters. Oh, … had to qualify right after chow. Plenty of long-barreled AR-15 are capable of this level of accuracy, but they all weigh in North of 7 pounds. And the top end AR-15 manufacturers need to get away from fabricating “government profile” barrels. It isn’t a shovel, it isn’t a hammer, it isn’t a pry bar, and as for bayonet charges, you’re not going to do one. BSF Barrels – AR-15 Barrel Carbon Fiber 223 Wylde 1-8 Twist. For general purpose, a new manufactured Nitrided pencil profile should be more than good enough. SNAP ! Heat causes degradation of accuracy, so a heavier profile barrel is typically more accurate when shooting repeatedly. That would have been because of a change in barrel harmonics due to being pinned at the wrong point. The acronym is MEDEVAC. I’ve reviewed several of their barrels over the years and really like their stuff for the price point. Scuttlebutt was, in the 80’s when the M16 A2 was adopted, that the reason the main barrel remained thin was to mount the M203. ….Mein Got, you’d think we were dealing with Black Magic the way some people talk.

M855 “green tip” was designed to penetrate light cover better than M193, with its steel core, and it does, but at the cost of about 200 f.p.s. And, they say, it worked as designed. With a 16″ barrel taking 100 off the muzzle velocity, it’s 100m/140m. On May 13, 2019 at 4:52 pm, Matt Bracken said: The M-16A1 with (as I recall) a 20.5″ pencil barrel was meant to max out the velocity of the M-193 55 grain bullet at a nominal 3,250 fps. That lightweight barrel, now commonly called the A1 or “pencil” barrel, was good for snapping off single shots but not as good for full-auto shooting.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). I was in the Service when the -A2 came out. My DI was a decent guy and took me to an unused range AR15.COM is the world’s largest firearm community and is a gathering place for firearm enthusiasts of all types.

Check great and honest reviews! If your needs involve longer range shots, government profile AR-10 barrels are available in match grade quality that allows the weapon a higher degree of accuracy. The government profile barrel is also … Listen to me. not cleaning up the burr correctly. Viewed as machines, guns are really very simple mechanisms, even automatics. This was where the Armorer’s Drop Gauge was getting stuck. Im looking to get a 14.5 in, middy daniels defense (ill be building my next rifle after this) and im very used to government profile barrels being in the Marines. Ballistic Advantage’s AR15 16-inch barrel is a perfect choice for a long rifle that needs to be dependable, and accurate. The gauge wouldn’t pass through the bore, so the assumption was that the barrel was “bent.”, We (Marines) were replacing a lot of “bent” barrels that were determined to be “bent” because the Armorer’s Bore Drop Gauge would not freely pass through some barrels during Ordnance Inspections (LTI’s). They obviously never got real engineers involved in this problem. For shooters looking for an SPR barrel, the barrel is lighter than full HBAR profiles and has plenty of accuracy for precision shooting.

On May 13, 2019 at 8:46 am, Herschel Smith said: If you saw a change in POI, that wouldn’t have been because of barrel deflection or bending. 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. On May 13, 2019 at 2:10 pm, Cold Warrior said: Interesting read, thank you. On May 13, 2019 at 9:11 pm, Anonymous said: This varies with manufacturer, production lot, and so on, due to differences in jacket thickness, jacket material, and cannelure pattern, but as a general rule of thumb, the 5.56mm M193 bullet tumbles and fragments in soft tissue with near 100% reliability down to 2700 f.p.s. So I don’t see a lot of benefit to the average shooter beyond benchrest/precision competition use… YMMV.

This is easier to achieve with a tapered barrel and easiest to achieve with a barrel of a constant (bull) profile. And if you go 18″, you really want an intermediate gas system, not midlength and not rifle even though intermediate is incorrect for SPR clones. The best point to pin a barrel is not at all, i.e., the floated barrel fixes all of that. Next Level chose this barrel after evaluating several options. So we went with this “improvement.”.

On May 13, 2019 at 8:16 am, Dean M Drews said: I totally agree. Most discussions around profile revolve around the 5.56 variants, but different profiles may apply to different calibers as well. Many of the barrels sold now (and PSA sells container-ship loads of them) are “A2 profile.” On a gun whose role is one where ‘handy’ is in the job description, they are a beast, solution in search of a problem. -Bayonets — not saying never but as civilians we can carry sidearms regardless of “rank.” Bayonets are often used for soldiers prohibited from carrying sidearms. Matt Bracken – Whoops, left out — big fan of your books. I favor a mid-length gas system which, with a 16-inch barrel, positions the front-sight/bayonet lug the same distance from the muzzle as the 14.5-inch M4 and the 20-inch M16A2/A3/A4. Govt profile has to do with the profile under the handguards. With the problem solved, the new barrel design went into effect. Which brings me to my favorite part about these government profile rifles – weight. On the defensive and running out of ammunition, the British fixed bayonets and charged the enemy, routing them at no cost to themselves while inflicting twenty or so casualties upon the opposition. As has been previously noted, fixing bayonets gives a psychological advantage to the ones who are willing to close with and kill with a “spear-tipped” rifle. Every fully melonited Voodoo Innovations barrel comes with a Lifetime Warranty and 1MOA accuracy guarantee. From there down to about 2550 f.p.s., it fragments about half the time. Unfortunately very few dot gov folks use suppressors. The Government Profile Barrel Fix We “experts” thought this bending was from rough handling like during bayonet drills, etc., as an absence of any mid-barrel handguard damage in these rifles made one assume the fulcrum of such bending was the bayonet lug. Ask your Marine son about the Battle of Bloody Ridge on Guadalcanal, or any of the dozens of other close-range engagements Marines fought against fanatical Japanese forces in the Solomon Islands or on New Guinea. Your next qualification score will be the LAST thing on your mind! That put it on the map for me…and I was happy to get my hands on one of their Hanson barrels after.

I have a Bushmaster AR, 20-inch, 1-9 twist, with a thick profile under the hand-guard and the standard government-profile from the front-sight-assembly forward. The Marines have always prided themselves on their marksmanship skills. Beyond velocities, the greatest benefit of longer barrels is greater sight radius if using irons — if using optics this second-level benefit is no longer applicable. “Affect” isn’t just use in an emotive context. There was no going back. Faxon also has precision profile barrels that are fluted w/ 5R rifling that weigh similar to BA, but are something like 30% more expensive IIRC. I remember that a switch to the heavy barrel was to alleviate that.. I can totally relate to- If you’re doing a bayonet charge, you failed to do whatever you needed to do to make it a stand-off fight. 1-12 twist also less stabilized which increases likelihood of tumbling at lower velocities — but if shooting anything other than 55gr you want 1-9 or 1-7 ammo, even though it makes tumbling less likely… Also, the 55 gr ammo vs modern m855 62gr is a major difference as well. Vietnam combat vets I know well affirm that it was deadly stuff, hauling ass and barely stable in flight, ready to tumble and break apart on contact. AR15.COM is the world’s largest firearm community and is a gathering place for firearm enthusiasts of all types. The open-prong flash hiders worked great to break those steel bands!

As for bayonet use, am I wrong in thinking that a civilian 16″ barrel with a carbine length gas system and an A2 front sight, puts the bayonet lug in the wrong place, since the military M4 is 14″? If this is the hottest area of a barrel, a government profile barrel seems to make less sense. DAN III – Thanks for catching. Colonel, US Army (Retired) Details. This is the one that Lt. Col Lutz ascribed to, at least somewhat. So they made only the front of the barrel thicker to increase strength.

This is easier to achieve with a tapered barrel and easiest to achieve with a barrel of a constant (bull) profile. As far as “prying open crates” what folks are talking about is using the original open-prong flash hider to break open the steel “band-it” straps around wood ordnance crates. They shoot fine but are often simply a nose-heavy PITA. The problem with longer barrels is that they result in reduced accuracy, albeit higher velocities. The highest bending moment in a cantilever beam will be where it is pinned, which in this case will be at the receiver. I have had unbelievable success with the DD pencil barrels. (Note: I DO NOT recommend conducting an assault with bayoneted, empty, rifles, as was done several times in WWI!) Engineer types might appreciate that. Not the barrel profile. Who will wait around, saying, “Hey sarge, you got some cutters for this steel band?” Hell no. There are so few of us left…. Third, if you believe the problem is that Soldiers or Marines are using their rifles to pry open boxes or crates, then teach them not to do that. The BCM 20” government upper and barrel is a quality piece of hardware that will certainly scratch that “retro” itch you might be feeling. I think civilians need to start thinking more about the uses of the bayonet. We had 1 day to zero and qualify Marine Lt. Col Dave Lutz was the program manager for the M16A2 project from 1980 to 1983. There was no going back.” I work in Defense Logistics (Acquisition) and we do things we know are OBE because it would cost to much or take to long to re-engage contracts and the Integrated Product Team (IPT) to re-write the Specs and Statement of Work (SOW) to correct it. I thought the Gov profile was dumb on the face of it from the first moment. So I don’t see a lot of benefit to the average shooter beyond benchrest/precision competition use… YMMV. This barrel is in the style of the original A2 government profile 20” barrel except that the muzzle is turned with a competition crown. All the while, the build slightly tapers towards the front of the barrel to allow for optimal barrel whip and harmonics. The doctrinal method of use had the shooter pulling down on the sling under the hand-guard in order to keep the rifle steady, and this caused the bullet-strike to hit high.

God help us. 1. The second law of thermodynamics says that entropy always increases. Milspec isn’t better. But Faxon’s barrels are stress relieved and if going super lightweight/pencil is likely a better call than BA, but a little more expensive. Only later did the team realize the actual cause of the drop gauge failure was something entirely different. The Marines were the driving factor in the adjustable rear sights of the M16A2 as well. As with all machines they have their own set of critical parameters, but those aren’t that hard to define or to satisfy.

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. Some guns and parts are better than Milspec, and some are worse. Got back and shot a 93 out of 100. Another story tells us that aggressive bayonet drills were the source of bending. However, I did use my carry Ka-Bar once to pry open the seal on a case of 5.56. Barrel material is 4150 Chrome Moly Vanadium 11595E Steel, Chrome Lined in both Bore and Chamber for long wear and ease of cleaning. Pencil barrel stress and heat zero testing. I have started eyeing my Gov’t profile barrels suspiciously. If you want beef, it would seem better to have it where the heat is the highest and the Marines put it out towards the muzzle. AR-15 lore tells us that GIs were using their rifles as pry bars to open crates, and they were bending the barrels by the muzzle doing it. The barrel profile is not significant any longer.
