So when I run the SS Manually it doesn't release the hammer when the upper is on, but if I have the upper off it releases. So what's happening is when the upper is on and I fire a round it resets the trigger and if I release the trigger and pull it again it will then allow for the hammer to drop. It's like the trip isn't pushing the SS lever far enough forward to allow the trigger to depress and drop the hammer. Have any of you ran into this or know what's going on? The SS works perfect in my AR's and in my DB alloy so I know that the trigger is cut right
It's common on AR22s to have to shim the slot in the cam to snug up the lever a little bit. The alternative is to tweak the geometry of the trip. Bore Buddy makes an adjustable trip for that exact reason.
