Spare WE 1911 MEU single stack 15 round magazine. The only difference between this and the standard type is the rubber ranger plate on the bottom of the magazine. It will still function properly in all single stack WE 1911 gas blowback pistols. As with all magazines of this type it is good practice to place your thumb over the BB loading port when drawing the BB follower back to ensure that the spring cannot escape through the port. Additional depth of ranger plate may require a gas bottle nozzle extension piece.
