Well, my fears were somewhat confirmed today. Gonna do some more tinkering before I give up but initial groups are sub par. This is my third trip to the range with this upper. Broke in the upper in previous two trips with lots of cleanings between shots. These are the 30-50th shots through the barrel. 27.6 gr - 28.2 gr of Tac under 123 gr SSTs. Not sure how to throw pics up on here, but groups were 2.3-3.6 MOA. Gonna try a better muzzle break than the flash hider than comes on it and some and some Noslers next trip, but looks like I definitely should have went with the group buy barrel as all suggested on here.
