I've been working on this 392 for a varmint gun. It came with the Sheridan forend I added the Sheridan trigger guard, Mac-1 extended pump arm and other parts. It's kind of splotchy and far from perfect
. It's worked over enough to get about 600 fps out of 25 grain pellets. Kind of a 22 short extra slow, very hard on cheap swingers
. Guns like this are so versital I've been thinking about making QD mounts for different scopes.
