Has anyone tried the ISMI recoil springs kits? I like the idea of the bushing for the guide rod, is that in place of a washer? Like I have stated before, I'm just weary on the washer thingy. Don have you thought of something like the bushing that is used on the ISMI recoil springs kits instead of a washer? I know your mechanically inclined so I was just wondering if you have prototyped anything like that yet? James, have you received any feedback on teh iISMI recoil springs kits? Thanks, trying to figure out what GR i'm gonna buy.
