If you're building a Hi-Capa and want a different look or a longer barrel profile, the Atlas Custom Works 4.3-inch stainless outer barrel gives you that without changing how the gun runs. It's a drop-in replacement for the factory barrel on Tokyo Marui Hi-Capa GBB pistols, so you're not machining slides or hunting for adapters.
The barrel is stainless steel, which handles heat better than aluminum and resists the wear that comes from thousands of rounds through a competition pistol. Brown finish on the outside. The threading is 11mm CW, the standard for Hi-Capa muzzle devices, so compensators, flash hiders, and most tracer units will screw right on.
This is an external upgrade. It does not change your FPS, hop-up, or internal air seal. The inner barrel and hop-up unit remain the same as stock. What you get is a different profile and a bit more weight up front.
Package includes the outer barrel only. Your Hi-Capa's inner barrel, hop-up chamber, and slide stay as they are.
