I have the same stock. I modded the mag follower to hold the 6th round in the mag. The magazine snaps into the gun a lot better if you only put 5 rounds in the gun.
Point of impact only changed 1" down and half inch to right after I swapped stocks at 100 yards. Its been dead on ever since.
I put in the swivel mounts. They are in there good and I dont think theyll pull out or strip.
