Great barrel - Ballistic Advantage Modern Series 5.56x45mm Barrel

.75 MOA on a 11.5 barrel. was very surprised with the performance of this barrel for the price I paid. didnt require heat to get into the upper which worried me at first but with this accuracy I can't argue with the results. came super clean with no tooling marks, there are no dimples on the bottom of this barrel so you will need a dimpling jig, the gas port wasn't massivly oversized like alot of manufacturers are nowadays so it was super nice to not have to spend forever with buffer weights ect trying to tune the weapon.
