If it's like my milled Bulgarian SA-M5 with a Steyer hammer-forged barrel, it should group with all but the best match grade ARs.
I just corrected one of the biggest problems with this rifle.
Magazine lock up was incorrect.
Ive only shot this thing open sight and its acurrate. Just added the POSP sight and havent zeroed it yet.
The stock is a tad short and I will add 1 and 1/2 " to the butt pad to fix that. Should rock and roll after that
