I read in the stickies, that regular cocker trigger frames are 100% compatible? Did I read that right? I ask because I'm looking at a SF, and I'd only buy it if I could easily aquire a mech frame for back up. Also, is there any issue with the shroud not fitting some barrels? Last is, I plan on running the air on gun, but not with a reg. I'll be using an Intruder
so will an HP tank, like ruin the marker?
