Atlas Custom Works Infinity SVP Stainless Steel 5.1 Outer Barrel for Hi-Capa GBB Pistols, Black

If you are building a competition-style Hi-Capa or refreshing an existing GBB pistol, the outer barrel is one of the upgrades that affects the profile. This is Atlas Custom Works' Infinity SVP 5.1-inch stainless steel barrel for Hi-Capa gas blowback platforms.

The 5.1-inch length is the standard full-profile Hi-Capa outer barrel found on most competition setups. It is machined from stainless steel, which resists corrosion and holds up to regular field use.

This is the outer barrel only. It does not come with an inner barrel, hop-up unit, nozzle, or mounting hardware. You will need to source those separately if you are doing a full barrel conversion. For a simple replacement on an existing build, make sure your current inner barrel and hop-up assembly are compatible with the ACW Infinity SVP housing.

Designed for Hi-Capa GBB pistols. The barrel threads and mounting points follow the standard Hi-Capa pattern, so it should mate with most factory and aftermarket slides that accept a 5.1-inch outer barrel. If you are modifying your slide or using a non-standard upper assembly, verify the fit before you buy.

Includes the outer barrel. Installation requires basic gunsmithing tools and knowledge of Hi-Capa disassembly.
