Lancer Tactical Stainless Steel Threaded 127mm Outer Barrel for 5.1 Hi-Capa Pistols, Rainbow

The 5.1 Hi-Capa is a popular gas blowback pistol platform, and swapping the outer barrel is one of the easiest ways to change its profile. This Lancer Tactical stainless steel barrel gives you a shorter, threaded profile that's better for carry or a leaner silhouette without sacrificing the pistol's core balance.

What you're getting. A 5-inch stainless steel outer barrel with threading at the muzzle. The stainless construction resists corrosion and holds up to repeated field use. The 5-inch length is compact enough for concealed carry setups or when you need to maneuver in tight spaces, while still being long enough to maintain the Hi-Capa's typical balance.

Threaded for accessories. The muzzle is threaded to accept standard airsoft muzzle devices—flash hiders, compensators, or mock suppressors. If you're building a specific look or want to reduce muzzle flash, you can screw one on directly. Just verify the thread pitch matches your chosen device; most airsoft barrels use the common 14mm standard.

Installation is straightforward. This replaces the factory outer barrel on 5.1 Hi-Capa series pistols. You'll need basic tools to remove the slide and swap the barrel assembly. If you're not comfortable doing this yourself, a local tech can handle it in minutes. The package includes only the outer barrel—no inner barrel, hop-up unit, or other internals are included.

What this won't do. Swapping the outer barrel alone doesn't improve accuracy. That's determined by the inner barrel quality, hop-up setup, and BB consistency. Think of this as an external upgrade for profile, weight, and accessory mounting—not a performance fix.

Compatible specifically with 5.1 Hi-Capa series gas blowback pistols. Check your pistol's model number before ordering to confirm fit.
