Hi-Capa 4.3 Xtreme .45 Custom GBB – Full Auto
Tokyo Marui Hi-Capa 4.3 Xtreme .45 Custom GBB – Full Auto Only (Silver/Black)
The Tokyo Marui Hi-Capa 4.3 Xtreme .45 Custom is the ultimate “spray-and-snap” sidearm: a full-auto-only gas blowback pistol built around a dedicated automatic engine that pushes an insane ~25 rounds per second. If you want a CQB monster for Speedsoft, aggressive entry work, or pure fun factor, the Hi-Capa Xtreme delivers the famous Marui efficiency with a brutally fast cycle and a satisfying kick.
Based on the compact 4.3 format, it stays quick in the hands and easy to draw, while the full dust cover chassis adds stability and features a 20mm accessory rail for weapon lights. Combine that with aggressive slide serrations, a durable tactical rear sight, and a big Hi-Capa magazine, and you’ve got one of the most iconic full-auto gas pistols on the market.

Key Features
- Full-auto only – dedicated automatic engine with a wild ~25 RPS rate of fire.
- Variable hop-up – tune BB backspin for a flatter trajectory and better effective range.
- 4.3” tactical slide – compact handling with front & rear serrations for confident racking.
- 20mm under-rail – mount a flashlight for indoor arenas and low-light play.
- Lean tactical controls – practical ergonomics made for fast manipulation.
- Lanyard loop – tether your sidearm for milsim/security roles and vehicle use.
- Hi-Capa platform – huge aftermarket support (slides, triggers, barrels, hop parts, HPA adapters, mags).
How It Plays
This is a close-range bully. The Xtreme excels at fast peeks, snap transitions, and short “buzz-saw” bursts that overwhelm opponents inside 10–25 meters. Set your hop-up properly, run clean BBs, and keep bursts controlled—full-auto will empty a mag fast (and that’s half the fun).
Gas Recommendation
Tokyo Marui pistols are designed for low-pressure “Light Gas” (144a / low power gas) such as Nuprol 1.0 or equivalent. Using stronger gases (standard Green Gas / Red Gas) can increase stress and wear, and may void warranty coverage for damage caused by excessive pressure.
