Description

FINALLY! This is the AP-9 9mm Pistol by Derwood. The AP-9 is inspired by the Shuty MP-1 and Gluty, also by Derwood. Special thanks to Warfairy for his contributions to the lower receiver for this project. The upper, bolt design and ejector have been improved and the overall design is easier to make.

Note (Optional): Derwood also included a STEP/Gluty_Parts folder for those wanting to use the Gluty lower instead of the AP-9 Lower receiver. Enjoy!

after you drill the hole in the small part of the bolt use the plastic guide you print to mark the centerline on the bolt pieces for a quick alignment for *welding
#8 x 1.5-inch hex head sheet metal screw can be used to hold the barrel retainer on if you cannot find #6
slightly countersink the holes where the plastic meets plastic.
