This 9mm chambered 4.5 inch Modern Series Barrel is machined from 4150 Chrome Moly Vanadium steel with a QPQ Corrosion Resistant Finish and 1/2-28 x .400 full profile threads. Designed to work with both Colt/RR and Glock style AR builds. Compatible with standard mil-spec uppers. There are also numerous dedicated 9mm upper options that work.

Threaded 1/2x28 or 1/2x36 to give you greater versatility when choosing a suppressor. Integrated feed ramp and barrel ex Mfg: Ballistic Advantage
