wi, I took mine up to the Kifaru LR shoot/clinic deallie tuesday and wednesday. Garrett Bussinger had a 3 shot, 2 inch group at 600 with no wind. It sucks to get out-shot with yer own gun......
Also ran Accurate Mag 10 rounders, AICS 10 rounders, P-Mag 10 and 20 's thru it with no problems. Feed and function was great no matter what I stuck in 'er....
