Atlas Custom Works Tokyo Marui Hi-Capa GBB 3.9" Type 2 SV CNC Aluminum Frame, Red

The Atlas Custom Works 3.9 Type 2 SV frame is for Hi-Capa builders who want a compact, full-metal platform without the bulk of a standard 5-inch build. At 160mm, it's sized for one-handed carry and tight gear setups while still accepting the full range of Hi-Capa internals and magazines. The SV-style contouring gives it a distinct look compared to stock TM frames, and the CNC aluminum construction means it's built to handle the snap of a GBB cycle without flex.

What you get. The package includes the frame itself, a stainless steel sear, valve knocker, and pin set. This is a parts-level upgrade, not a complete pistol—you'll need to source your own slide, barrel, hop-up unit, and gas system to finish the build. It's designed for Tokyo Marui Hi-Capa Series pistols, so compatibility is specific to that platform.

Before you buy. This is a red-anodized frame, and the finish is cosmetic only—it doesn't indicate FPS, port size, or any performance spec. If you're building for competition, verify your local rules on frame materials and dimensions. Assembly requires basic gunsmithing skills and proper tools; if you're not experienced with Hi-Capa disassembly, budget for a certified technician to put it together. The frame alone won't make a functional gun.
