1) does anyone have the specs not pics only but actual measurements for the body rail slot?
2) I am new to mags (building one actually) and would love to use it for pump play as well as semi. How diffacult is it to switch from pump to semi with the pump kit? Does one need to remove the pump or just the "cocking rod" and wave spring? About how long would it take? I seem to remember the reviews when these first came out impling that it was fairly simple, but is it?
3) how well do these pumps work?
