A: Yes sir, so long as it hasn't got a 223 Wylde chamber. CMMG only specifies this part for 5.56/223 chambered AR-15s.

A: Absolutely sir! CMMG specifically designed this conversion kit for 5.56 AR-15 rifles.
We're not affiliated with this fellow, but he offers a good demonstration of the kit on his channel: youtube.com/watch?v=UHGTEOErXMU&ab_channel=C4Defense

A: This kit will work with most AR15 rifles. The only specification from the manufacturer is that the rifle MUST have a mil-spec chamber. You can find more information at the website. https://www.cmmginc.com/faq/
