Testing my REPLACEMENT Bear Creek Arsenal 16" 6.5 Grendel M4 Profile Barrel (Part II)

The following is a brief look at the following Bear Creek Arsenal Barrel:

Model: 119-B6.5Cm41618(M)

Length: 16"
Caliber: 6.5 Grendel
Rifling Twist Rate: 1:8
Gas System Length: Carbine
Barrel Profile: M4
Feed Ramps: M4
Barrel Material: 4150 CMV
Finish: Melonite (Nitride)

This is a test of the replacement barrel that BCA sent me after I returned the first one because of poor accuracy. TLDW: This barrel is a dog too.

Because this is a "beater" build, I tested Wolf Steel Cased 100 grain ammo only. Premium ammo gets pricey really fast when you get a barrel that won't group.

Groups shown were shot from a concrete bench, with front and rear sandbag rests.

Range conditions:
Temperature: 75F
Wind: 15mph gusts

Barrel was cleaned before shooting.

Build notes:

-Upper receiver was lapped and squared prior to assembly.
-Barrel was using standard carbine handguards
-Barrel extension and upper receiver had a tight interference fit.
-Barrel nut was torqued and loosened 3x before final torque value of 85 ft/lbs was applied.
-Gas block was aligned properly, and taper pinned.
-Muzzle device used a crush washer, but was pre-crushed before installation so that it could be installed only 1/8th of a turn past hand tight.

Lower receiver has a polished, adjusted GI trigger that breaks cleanly at 4.5 lbs.

As with all videos I post, I'm not sponsored in any way by anybody or any entity. I'm just a guy who likes to test cheap barrels.

This review may not be indicative of every barrel bearing the same model. This is just my experience with this barrel.
