Funny this post came up. I just got off the phone with Impact Guns about 30 minutes ago; my second S12 just arrived today. :bangbang:
Yea, I get on there occaisionally. I saw where someone was offering a bolt on conversion now. Haven't looked into it too much though.
So far I'm thinking:
S12 #1 = Folding Tromix stock, 8" barrel, Shark brake, maybe some HK-style or ghost ring sights, as well as whatever other magic Tromix can do.
S12 #2 = Fixed Tromix stock, 12" barrel, Rem chokes, competition brake, and maybe a C-more or other red dot/reflex/holo sight.
I need more $.
