AR 15 Lower Vice Holder

thingiverse

I wanted to accurately align my AR15 scope so I created this adapter from scratch. The primary objective was to produce a ramp with the precise angle of the mag well in mind. One end is positioned against the mag well while the other end is securely held by a vice. Don't forget to push the mag release before fully inserting the adapter into place. I printed two instances of the part, one mirrored across the x-axis and flipped both halves 90 degrees around the x-axis to lay them flat in preparation for assembly. The small holes are designed to accommodate short pieces of 1.75 mm filament that serve as keys while gluing the parts together. The adapter was printed with a 20% infill using PLA material. Enjoy!
