I tried to quote the replies, but that button does nothing for me.
anyway, re: the charging handle. I dont think that's a project that I would attempt. My welding skills arent that good. No big deal if a sight pops off, but I think I might need the charging handle.
and re: does it run....well, that depends on the ammo. It doesnt cycle #7.5 shot, but it does cycle #4 shot and of course 00 buck. I need to pick up a variety of birdshot between 7.5 and 4, and see what will run. I would have been happy if it only cycled buck, anything else is a bonus IMO.
