Questions & Answers
Hi I need a buffer tube assembly for fixed stock for a 9mm build I currently have the Fm 9mm lower with pistol grip. Can any 9mm upper be used etc? Expert Answer

No, you would have to at least match the carrier to your magazine type. If your lower is a Colt SMG-style lower, you will need a Colt compatible bolt carrier, and if you have a Glock-style lower, you will need a Glock compatible bolt carrier. There are also some carriers, such as the Faxon one, that will work with both Colt and Glock magazines. The barrels themselves are the same.
