Solid upper for CMMG AR-9 build by chowar07, Verified Owner, March 2, 2024
Built a CMMG RBD 9 mm upper using one of these last year. I liked it so much I'm building a second one for my wife. It's a tighter fit for the barrel than the CMMG mk4 upper but it works if you use a heat gun on it along with Aeroshell.
