As long as the bolt doesnt reset the any frame will work. Many years ago i missed a purple hyperframe i wanted for my purple pumpmag. Why? Because in less then a minute you can change the gun from pump to semi and a electro frame is nice for fire power.
Call me unenlightened but what would all the pneumatics do on a pump mag?
Looks sweet though.
i don't see the point but i thought it was different
So once again someone could pose the question " why would he do that"...answer...because he could. He probably uses that same trigger frame on multiple setups. I always wonder why people use X valves on pumps, it seems like the perfect place to use a classic valve. But hey who am I to say what valve a man should use on his own Mag.
I think 'reebs has some pump-pneu-mags.
