I was wondering if anyone has one of these uppers as well. I know its cheap but it actually shoots the 75 grain AE rounds well. Rings Steal at 500 easily and it feel 600 would be easy as well. Ive been reading everything i can find. It seems each Brand of Barrel has pet loads it likes. Ive got some 80 grn and 88 grn ELDM's loads with loads I've found. Would like to hear from anyone with one of these uppers
