One of my favorite shooters also I put wood on mine otherwise identical. Use the 6x on it as well. Mostly the 106cr gets the Bars dot except when shooting longer range steel. I use that arsenal grenade launch butt pad on about every AK I own including on the underfolder and FPK, (6’2 need the extra length). Here it is on my 1997 Roma 5.45 and same year FPK import.
