The Brownells Government Barrel Assemblies are manufactured by a US Government Contractor for M4 barrels, and held to exacting standards. These barrels all feature a hard chrome bore, applied over button rifling. Each barrel is High Pressure Tested, followed by Magnetic Particle Inspection & Gauging to ensure there are absolutely zero imperfections. Assemblies are as ready-to-install as possible, with slip ring assembly, non-marked front sight base and handguard cap pre-installed. Handguard caps are appropriate for the barrel length, with M4 Carbine assemblies featuring a round cap, and the rifle length featuring the proper triangle. Barrel material is 4150 chrome moly steel. 5.56x45mm chamber and 1-7 twist will ensure acceptance and desired performance with 62 grain and greater bullets.

Very nice classic style barrel

Barrel parallels USGI style barrels. Parkerized exterior, chrome lined bore, taper pinned front sight, and just done right. The delta ring was a nice matte finish and not the shiny nitride stuff that seems so typical these days. The weld spring for the handguard was a little soft and I put a stiffer version in, otherwise this assembly is perfect.

Great for the price!

Nice retro grey coloring to the barrel and FSB. Shot accurate to 25 yards right out of the box and onto my upper, hasn’t really needed a breaking in period. FSB is aligned and no complaints at all! Can’t say too much about longevity or anything yet, but so far I am happy! I bought the Socom barrel which is heavy but the U.S uses them as they are more durable for sustained fire.

Seems like a decent barrel (14.7 Government).

I like chrome-lined 4150 barrels for ARs and everything looks good on mine: the chrome lining looks well done; the Parkerization is even on everything; the front sight base (FSB) is straight; and it even comes with the front sight post, sling swivel, and a delta ring installed. My muzzle device spun on fine and the barrel extension slid into my Rock River Arms upper receiver without being too tight or with slop. It has M4 ramps. The barrel markings are behind the FSB, so they're covered by whatever handguards/rail you use. I've only put a few rounds through it so far, but I got a five-round group of about 1.5 inches at 50 yards using a red dot sight and XM855 ammunition (which certainly isn't precision ammunition!) It slings XM855 cases to about 2:30, but that's with a standard carbine buffer and spring. I'm very pleased with this barrel.
