Good overall - CMMG, Inc 22ARC 10 Round Rifle Magazine

I bought three of these magazines and all of them work fine. I got to say they feel solid and durable. On that note I haven't tortured tested them or done any stress test with them. They feed just fine if you don't hold onto the magazine or mess with it. The open bolt hold feature is great, makes it easy to know you fired the last bullet. So far it feeds well with Federal and CCI brand 22 LR ammunition. I don't really mind the weight of these magazines but some people might not like it. Overall I'm happy with my purchase and would recommend this to anyone that has a AR15 22 LR conversion kit.
