Retired W4
Bearcat
I am finally getting around to fixing the cycling problem with my AAC suppressed Mk II. I use RWS subsonic and I have always just put my thumb on the bolt and feed the next round manually. I ordered the Volquartsen kit and also did some light polishing on the hammer face and bottom of the bolt. The polishing has smoothed out the action. Has anyone had experience with the spring kit in this configuration?
