Brownells Government Barrel Assemblies – Chrome Lined and Individually Inspected

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. This manufacturer works with trusted US based partners to source MIL-spec assembly components including barrel extensions and front sights.

  • Material selection
  • Blank Preparation
  • Drill / Ream / Rifle

16 MOA junk
This is the worst AR15 barrel I've ever owned or used. I can't get a group smaller than 4 inches at 25 yards. I can't hit a 12" plate at 300 yards. Save your money. I built this into an XM177-ish with a nice geisselle trigger. Shot it side by side with a PSA H&R M16A1 with a GI trigger. The PSA didn't even make a clover at 25 yards and when zeroed at 200, I couldn't miss that 12" plate at 300. How would any AR possibly shoot worse than 3MOA? The answer is: Brownells.

Mk18 10.3” barrel clone
If you’re looking for a clone correct mk18 mod 0 barrel, this is not it. This barrel is a non F marked and the clone correct is F marked.
