This is an Autococker pump arm intended for use with a full valve body but mini and mid blocked Autococker such as many WGP guns or the Empire Resurrection.
This pump arm is very easy to install thanks to the cross drilled hole that allows you to lock the arm in place by putting an allen key through the hole so that you can easily screw on the ram to the front or the back block to rear avoiding any "idiot" marks caused by pliers or other tool on the pump arm. So easy to do you wonder why they weren't always made this way...
We stock Full body and mini length pump arms, but midblcook and mini/mid are avaible to order. Email Greg@NuclearPaintball.com for special orders
