AR 10 and AR 15 Upper receiver hangers

Here are some AR 15 and AR 10 upper receiver hangers for Gearwall slat wall.  Printable T nuts included.  I used ¼-20 threaded heat inserts and stainless ½ inch screws.

Two versions of each are included.  Once leaves the upper open ended while the other caps the receiver and holds the Bolt Carrier in place.  ¼ inch push pins are used to attach the receiver to the hangers.
