AR15 carbine receiver extension cover

thingiverse

This is a enhanced protective cover for an AR15 carbine receiver extension. Use it to save space when storing your AR15 rifle, AR pistol, or SBR without a brace, foam tube, or stock. Depending on how it's rotated the cover can be installed at three different depths. When stored muzzle up this flexibility can put the grips and other protrusions at different heights for really tight spaces. There are small relief cuts for charging handle clearance. Print in flexible material like TPU for comfort. Shoulder at your own peril.
