Ramp Bolt for use in Glock Magazine lower mods. Ramped bolts do not work with 9mm hammers. They work with most 2 stage triggers and all M16 style triggers without the notch.
This order is for ramping and narrowing of the bolt base for use with the 9mm Glock Magazines. (Lone Wolf Dist. or DDLES lowers for Glock Magazines.)
