Lancer Tactical Stainless Steel Fluted Threaded 5.1" Outer Barrel for 5.1 Hi-Capa, Red

If you're running a Hi-Capa 5.1 and want a barrel that looks the part while holding up to repeated gas cycles, this Lancer Tactical stainless steel outer barrel does the job. It's machined specifically for the 5.1 series gas blowback pistols, so the fit and finish line up with the slide and frame without requiring extra work.

Why stainless steel. Stainless resists wear from the constant gas blowback action better than cheaper alloys. The fluting cuts weight without sacrificing rigidity, so you get the look of a performance upgrade without making the pistol front-heavy.

Threaded for accessories. The barrel comes threaded at the muzzle, which opens up options for suppressors, compensators, or flash hiders. Check the threading specification before buying muzzle devices, as different manufacturers use different standards.

What you get. Just the outer barrel. No inner barrel, no hop-up unit, no mounting hardware. You'll need to transfer your existing inner barrel assembly or source one separately if you're doing a full build. The red finish is cosmetic and doesn't indicate any performance rating or FPS band—it's there because you want it there.

Before you install, verify the barrel length matches your slide cut. Hi-Capa frames vary slightly between manufacturers, and an overlong barrel can interfere with slide travel. Take five minutes to dry-fit before you commit to any permanent mounting.
