Ballistic Advantage Modern Series 16" .308 Win Tactical Government Contour 1:10 Nitride AR-308 Barrel - Mid-Length - 5/8x24

Picked this barrel up for an Aero Precision AR10 build thinking it was a no brainer with the Sub-MOA guarantee. It turns out that this barrel is terrible and will be going back to Primary Arms ASAP. It was professionally installed by my LGS and bore sited to a rough range. After about 120rounds of Hornady match grade ammo through this rifle, it is shooting all over the place. Everything is to spec as it should be. I’m lucky to hit a 5x5 target at 100yrds, much less 200yrds. I think I’ve got a fluke barrel. Fingers crossed Primary Arms takes care of me on this one!

Overall I am impressed with this barrel, its accuracy is pretty good for the price, however be careful with the mid-length system on a 308. I used this for a 7lb build and it has some pretty rough recoil. So far accuracy has been as advertised at 1MOA, but I am not using match ammo. I bedded this barrel in a Aero M5 upper and combined that with a low pro adjustable gas block from Midway. That combination has worked well, however I would recommend buying your BCG from Ballistic Advantage. Having the same bolt face usually increases accuracy, but the BCG from Aim Surplus has the proper head space to function with this barrel. It is a little heavier than I am used to but then again this is also a 308 barrel. If it was fluted like the other new barrels from BA it would be super awesome.
