Very nice rifle! And a nice grouping to boot!
I have this built about 7 years ago using kac urx, ops inc brake and compass lake engineering chambered Lijia bbl . 3.25" group at 300m using mk 6 1-6 shooting 77 smk on bipod without rear bag in snap shot practice against fig 14 type target.
Yes, MK12 spr has plenty of accuracy to make head shots ��
