Grandma’s Apple Pie Build Kit


You print the files, I’ll supply the hardware.

Grandma’s Apple Pie is the more traditional version of the Apple Pie released previous to this. The GAP is semi-auto and will accept the standard uppers and parts you’re familiar with for an AR15. This design uses a reinforced and replaceable front takedown section along with a metal buffer tower to overcome the common fail points of printed lowers.
