The long reciver screw supplied with my Speedfeed stock was about 1/2in too long. It protruded into the revicer, past the mounting block, and appeared that it could possiably intefere with cycling. I did  remove the trigger group for a visual inspection and there is a grove cut into the plate that seemed like it would accomidate the extra length of the bolt, however, there was not much slack room, and this being a defense shotgun, I didnt wanna take any chances, so I chucked up the mounting screw on the lathe and took about 1/2in off of it. Now the screw sits flush with the end of the mounting block inside the reciver.
Something you may wanna look at if you have a SpeedFeed stock.
