Can't be used on duty weapons - Timber Creek Quick Disconnect End Plate

This probably goes without saying, but these are aluminum. They won't last long if you use them. The one I received didn't even hold the qd end in. I also tried Magpul end, Troy end and Vickers end...they all work with my other end plates. This one it just falls out. I hoped they reinforced the socket to be anti rotational, but its just milled aluminum. Not great for any gun in my humble opinion. Sorry TC...Love your stuff usually!
