I want to learn more about these 556 adapters? How do I know mine will accept it? Mine is a 2013. Also and most importantly no machining to receiver.
Where can I buy the adapter and an XCR pistol mag to try?
Thanks
Andrew
I was talking to Steiner earlier today and he was able to track down the CSA adapter at Zahal for roughly $106 shipped (at least to Manitoba) and Wanstalls has some of the XCR mags in 7.62x39.
