Decent. Not great.
Barrel fit up was great. No feeding issues. Looks good. But that’s about where the good things end. Tried over 12 different factory loads through it from cheap to quality Match ammo, 55 to 77g, FMJ, ELD, HP, BT didn’t matter what i fed it, it spit it out in clusters. Best i got was 2-3” spread, most was WELL over 5”. This was all at 100 yards. Thought it may have been me not agreeing with the trigger i put in it, put the lower on another platform i have with a Faxon barrel and had no issues with sub MOA. So put it back on the upper with this barrel and locked it in a lead sled to take out any variables. Same LARGE groups. If you’re looking for accuracy like i was, get something else.
