Lancer Tactical Stainless Steel Threaded Outer Barrel for 5.1 Hi-Capa Pistols, Black

The 5.1 Hi-Capa is a popular platform for competitive airsoft and custom builds, but the factory outer barrel is often aluminum and unthreaded. This Lancer Tactical stainless steel barrel upgrades both the durability and the versatility of your pistol.

Why stainless steel. Stainless steel resists corrosion and holds up better to the heat and friction of repeated firing than standard aluminum barrels. It also provides a more solid mounting point for threaded accessories. If you're running your Hi-Capa hard at matches or in training, the material upgrade pays off over time.

Threaded for accessories. The barrel is threaded at the muzzle, which opens up options you cannot use on a standard Hi-Capa. You can mount a compensator to reduce muzzle flip, a mock suppressor for a different look and balance, or a tracer unit for glow-BB play. The thread pattern matches the standard Hi-Capa 5.1 specification, so common muzzle devices will fit without adapters.

5-inch length. At 5 inches, this barrel maintains the compact profile the Hi-Capa is known for while providing enough inner barrel length for consistent hop-up engagement. It is a practical length for IPSC-style stages and general field use without adding the bulk of a longer conversion.

Installation. Swapping the outer barrel on a 5.1 Hi-Capa is straightforward and does not require special tools. You remove the slide assembly, take out the factory barrel, and thread the new one into the slide. The barrel is black finish, matching the standard appearance of most Hi-Capa builds.

What you get. The package includes the outer barrel only. You will need your existing 5.1 Hi-Capa slide assembly and internal components. Battery, gas, and BBs are not included.
