Ok so for future reference. I have my 68/45 set for 850psi. The mag I'm looking for should have a retro valve? I'm gonna go with a lvl10 bolt. No eyes is gonna need that kind of softness.
Twist lock? Anything wrong with that? My initial desire is what stimpy mention with the use bodies since they're threaded. I saw one that was a fixed barrel...hmmm maybe no.
