Sten Magazine Adapter for AR9/AR15

Works perfectly, minimal fitting. I made a custom fixed magazine catch for my lower

The magazine adapter required extensive fitting to the magazine catch to get my magazines to lock in. Also, my magazine catch pad was slim/narrow unlike the nice wide one pictured. It’ll work and it’s priced low enough, but it could at least come as pictured and require less fitting. Haven’t done any live fire yet, but cycles by hand great with my CMMG RDB build.

This adapter is the best! I came into a stack of sten mags and found this adapter. It works so well, a couple of my buddies are boring the same build with this adapter. It's awesome and actually less expensive than any other adapter on the market.

Functions flawlessly with every magazine I tried. ? I'm running it on an anderson lower and it fits excellent.
