I actually had an idea for the bolt stop. Instead of welding a block on, drill and tap the factory bolt stop on the trunnion for a stop bolt with a jamb nut. Maybe even tack weld it after getting the headspace set. I can't remember how much material is there, so I don't know if it would support a 10-32 hole, or if I would have to do an 8-32. I'm pretty sure that a 10-32 bolt, correctly chosen of course, could handle the the linear compression, (especially if I washer it up to help support the shank) but I'm not sure that an 8-32 could handle the repeated pounding. I'm gonna check it out after I get home. May not need to be in much of a rush to get it ready to test tomorrow, as its supposed to rain. That sucks! The guy I was going with was bringing a 1919a4!!!!!!!!
ive wondered too if your bolt stop could be a piece of poly like a buffer?
