This is an 86 Degree Pivot frame with full auto trigger capability as well as a three way slot. With all the parts necessary to put it onto any old school WGP Autococker or WGP Sniper or an Empire Sniper (where the height of the 3 way slot does not matter.) It will allow the use of an auto trigger when installed on a pump gun. It will come with all of our upgraded internals including our Pivot trigger plate and roller sear and more!
