I'm tellin ya, sometimes I think these forums somehow read my mind. Not really in an AR but I've gotten the .20 Caliber bug as of late and instead of going semi custom, which I haven't 100% ruled out, I was just going to pick up another CZ 527 Varmint in 204 but being that I shoot everything with a can, as you all know, shorter is definitely handier when you screw a 6in can on the end so I was thinking of having at least a couple inches lopped off the end when it gets threaded BUT I wasn't exactly sure what that would do to the velocity. Now, after reading what many of you are doing with your AR 204's I'm considering maybe chopping it back to 20 instead of 22, although 18 + my can would just barely put me back to the original overall length as it comes with its uncut 24in tube which is pretty darn short for a bolt gun including a can. But I've also got a brand new Seekins SP15 that hasn't seen the light of day since I brought it home and I suppose I could just put a new barrel in that and go that route, too. Probably save myself some money and technically a barrel swap ISN'T a new gun so I wouldn't get any grief from the Warden either. Hmmmm, decisions, decisions.
Anyone have any suggestions on this? Besides the obvious of a new barrel, what's all involved in turning my Seekins SP15 223 into a SP15 204 Ruger? If I went 20-223ai couldn't I just use my 223ai dies but with the appropriate sized bushing???
