Basic Fixed AR-15 stock w/recoil pad & cheek rest, this stock clamps onto buffer tube (Mil spec-carbine) instead of pinning. It's designed for a #8 nut and screw to clamp and #6 to fasten the recoil pad in place (recommend washer so it doesn't pull through Urethane)
Stock PLA - Solid build, No need for supports (but watch the triangle cutout if you machine can't handle that steep of an angle you might want them) Printed standing on end - butt end on print bed.
Recoil Pad Urethane - This is fun to play with I used a 3mm wall and 30% infill Grid seemed to give the right feel for recoil absorption, play with infill makes a huge difference. Remember to run this stuff slowly.
