Firewalker,From the other thread, you said the stop broke. If you can take it apart and get a picture, that would be great. I had read that the carm mags are known to do this as well. I may have to thicken the stop some. I’m sure it’s the stronger spring pressure that slams the projectile into the stop that did it. I may have to ease up the spring tension some. It’s a trade off for the semi auto ability I suppose. Dave
