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.
