I'm going to be using my vepr 12 for duck, goose and grouse hunting (mainly to irritate my hunting buddies,lol, but that's another story). What are my choke choices, I've heard the poly choke is hit or miss because it was made for the saiga which has a tighter bore making a ledge when installed on some of them, then I see there is a kit of 3 chokes widely available for $99 that includes a mod, full and extra full (why no option imp. cyl. instead of x-full is beyond me) but it seems to be made for the vepr. I'd really like to find an adapter so I could use cheap win. chokes or rem chokes but can't find one. So do any of you guys have more options that I'm not seeing?
