Worked perfectly on my MP15-22P. Very easy to install. Added a SB1913 folding brace... very cool package now. Got pictures if you need/want them...
The part is made from 3d printed (SLS) nylon that has been media tumbled, dyed and painted black. Mounting hardware is included.
Installation: Installation requires drilling a small hole in the rear of your lower receiver for the anti-rotation pin. A 7/64 drill bit is required but not included.
CLICK HERE to see a great video from a customer describing the part and the installation. The video is for a tailhook brace but the installation is the same process.
