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

The Tokyo Marui Hi-Capa is the default platform for competitive airsoft pistols, but the factory frame is polymer and not designed for heavy use. This Atlas Custom Works 3.9-inch Type 2 SV-style aluminum frame replaces that weak point with CNC-machined metal that can handle the abuse of match play and frequent dry-fire practice.

What the SV style means. The SV cut is a shortened frame profile that reduces weight and improves draw speed. It's a common preference in IDPA and USPSA divisions where every gram counts and you're drawing from a holster repeatedly. The 3.9-inch length keeps the pistol compact while still accepting standard Hi-Capa slides and barrels.

What's included and what you need. The package includes the aluminum frame, a stainless steel sear, valve knocker, and pin set. You're replacing the entire lower assembly, so this is a build-level upgrade, not a quick swap. The frame is designed specifically for Tokyo Marui Hi-Capa Series gas blowback pistols — it will not fit other platforms.

Material and finish. This is CNC aluminum, not steel. That keeps weight down while still being significantly more durable than the factory polymer frame. The purple anodized finish is cosmetic and does not indicate any specific FPS rating or performance characteristic.

Before you buy. Installing a custom frame requires full disassembly of your Hi-Capa and reassembly with the new internal components. If you are not comfortable working on gas blowback pistols, have this installed by a certified technician. Improper assembly can damage your slide, barrel, or gas system. Atlas Custom Works has built their reputation on precision fitment, but the final performance depends on installation quality.

The frame measures 160mm in length and ships with all necessary hardware for installation.
