Check these modifications out if you own a Chinese shotgun. Looks like somebody else spent some money besides CSspecs to answer those expensive questions.
No, it's a friend of mine's who forked out the money to have his buddy experiment with the mags. If it works out for him, I was thinking about having it done or doing it myself. So far, evreybody I talk to says its got a good lockup on the trunnion and the pitch/angle feeds well. ?????????????????????????????????????
I told him to put it on Youtube so I can get other people's opinion before I try it myself or have it done. They don't really offer any options for these Chinese jobs. Hopefully he'll go to the range or take it out back in the woods and do a demo this weekend.
