RCM HK USP .45 ACP Tactical Barrel – Threaded .578×28 RH
HK USP .45 & USP .45 Tactical threaded barrel compatible with various flash hiders and sound suppressors. Unlike the factory USP .45 Tactical barrel, which uses a less common metric 16×1 left hand thread, this barrel features the more common US .578×28 right hand threads. This makes it easier to find compatible suppressors and flash hiders. A great combo package at a great price!
