This is not a weapon, nor a functional part for any weapon.

I designed this to aid in storage of my extra uppers by functioning as both a dust cover and a solid block to keep the bolt carrier group from falling out. I've seen commercial versions of this that all require the use of proprietary retainer pins, but I wanted something that I could pop on and off with friction.

File Version 1.2.1 Updated with a larger keyhole slot for wall hanging, my new logo, and reference info for both here and Thingiverse.

No supports needed, print with your favorite filament and settings. My test prints have been hot and fast on eSun PLA Plus with no issues. Keeping the infill down allows for a little flex on the friction points.
