According to the manufacturer the Angstadt Arms AR-15 9mm 5.4 oz Carbine Buffer Assembly w/ Carbine Buffer Spring will work with Colt and Glock magazines. They do not mention if the buffer assembly will work with AR magazines with a 9mm insert. I recommend contacting the manufacturer to confirm compatibility.
