Just wanted to throw this out there for anyone getting a Steiner MPS. I recently got a new one as I liked the original so much I wanted all of my staccatos to have the same red dot. However on install when I tried to torque it to the recommended 22 inch pounds the screw snapped. Steiner was great about a repair, and they advised me they changed up the foot and now only recommend 16-18 inch pounds. I guess I didn't have the same issue on the first because I replaced the foot with the apex improved kit. So if you get an MPS only torque it to 16-18 inch pounds instead of the recommendation in the manual.
