Nate W –
Superb machining quality and detail. I have an Armalite AR-10 (Def10) I bought this for and works flawlessly. Firing pin strikes the primers perfect and cycles great. Was worried it wouldn’t work because there are some after market products do not function with Armalite but this does. I have the mystic black and if you can find one in stock I Highly recommend you picking one up.
