Testing the Bear Creek Arsenal 18" heavy profile 6.5 Grendel barrel: A quick and dirty review

Model: 1169-B6.5MHB18185R(MF) Length: 18" Caliber: 6.5 Grendel Rifling Twist Rate: 1:8 5R Gas System Length: Mid Barrel Profile: Heavy, fluted Feed Ramps: M4 Barrel Material: 4150 CMV Finish: Melonite (Nitride) Groups shown were shot from a concrete bench, with front and rear sandbag rests. Range conditions: Temperature: 75F Wind: N/A Feed ramps were polished before shooting. Barrel was cleaned thoroughly before shooting, and after every 5 round group for the first 20 rounds. The barrel initially exhibited poor accuracy, but proceeded to tighten up groups as the day progressed. Notably, there was a rough spot about 1" from the muzzle that smoothed out as the rifle was fired. Build notes: -Upper receiver was lapped and squared prior to assembly. -Barrel was free floated. -Barrel extension was shimmed with .002" stainless steel shim stock to ensure a VERY tight fit into the upper receiver. -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 lbs. Thoughts: This barrel has potential. As it smoothed out, it started actually grouping, and I think it's probably capable of MOA or better accuracy with Hornady Black ELD-Match ammo.
