ExcellenceReview by Rubber
Using factory federal fusion I'm getting a .75 inch group at 150 yards. That should be .5 moa if my math is correct. And 4 out if 5 shots were touching, one got away. Very impressive. (Posted on 4/16/2019)
BA quality like usual Review by Brent
Great looking and functioning barrel. After the suggested break in procedure it put a 1” 5 shot mag fed group at 100yds with 123gr eld Hornady Black. Even with the shot I pulled it was still a 1” group with 3 touching. Looking forward to seeing how much better it gets when it’s broken in. Fantastic fit and finish as well. (Posted on 1/22/2019)
I think really love this barrelReview by John
Been shopping for a grendel about 1 year or 2. Already own 2 other BA barrels. So when I saw they came out I looked for reveiws and didnt see many. Wish I just bought it then. This barrel was accurate out of the gate. .461 lol. Yes only 3 rounds. But its consistent. 30.4gn cfe on 123 eld. 1 moa to 1.5 moa with varget. Cant wait till its broken it completely. Paired with 6.5 gamma and bcm upper. Shoots flat and ejects at 4 o'clock with BA gas block. So far I'm impressed. (Posted on 4/2/2018)
