Custom Tokyo Marui Hi-Capa 5.1 Prebuild Airsoft Pistol – Green, Silver & Black

This custom Hi-Capa brings together a vivid green slide, bright silver accents, and a black foundation for a sharp, coordinated look. The Dr. Black Type 800 green slide features extensive angular cutouts that reveal the LA Capa Tornado silver outer barrel, giving the upper assembly a distinctive layered appearance. A matching green LA Capa S2 flat trigger carries the colorway into the frame, while the silver magwell and hardware add contrast against the black grip.

Built on a Tokyo Marui Hi-Capa 5.1 platform, this prebuild pairs its standout styling with upgrades focused on responsive cycling and controlled shooting. The AIP blowback unit, Guarder full nozzle set, and CowCow 180% nozzle spring support the blowback assembly, while the AIP recoil spring and NEXXSPEED short stroke buffers help produce a quick, compact cycling feel.

The PDI 113mm inner barrel, Quantum GBB bucking, and TTI one-piece hop-up chamber provide a foundation for consistent hop application and accurate BB flight when properly tuned. An upgraded trigger bar, one-piece sear, and CowCow Trident sear spring round out the trigger assembly. The LA Capa Defender magwell helps guide magazine changes, while the NEXXSPEED magazine release keeps reload controls accessible.

Common Product Questions

Find quick answers about our airsoft products, shipping and policies.

Can LA Airsoft install this part for me?

Yes. We can build and upgrade Hi-Capas, AAP platforms, and rifles. Choose your base gun and parts, then add the appropriate tech service.

The current custom-build service states that builds are normally completed in approximately 3 to 5 days, with the team reviewing the selected parts for compatibility.

Do I need tools or gunsmithing?

That depends on the upgrade. Simple external parts may be straightforward, but internal upgrades can require disassembly, reassembly, adjustment and testing.

If you are not comfortable working inside your airsoft gun, our team offers professional tech and custom-build services.

How quickly will my order ship?

Orders without preorder items are typically packed the same day when placed before 4:30 p.m. Central Time. Please note that occasional delays can occur during especially busy periods or when staffing is limited.

How should I maintain this product?

Regular maintenance helps preserve performance and reliability. Keep the product clean, follow the manufacturer’s lubrication instructions, and properly manage batteries, gas systems, and internal components. More advanced repairs or internal servicing should be handled by an experienced airsoft technician.

Will this part fit my platform?

Compatibility is product-specific. Check the brand, model, size, and platform named in the product description, such as Tokyo Marui Hi-Capa 4.3 or 5.1, AAP-01, Umarex/VFC Glock, or a particular AEG gearbox type.

Similar-looking parts are not always interchangeable, so contact our team with your exact model if you are unsure.

Will this part increase my FPS?

Not every upgrade increases FPS. Some parts are designed primarily for reliability, cycling speed, weight reduction, or gas efficiency. When a product has a tested FPS claim, it should be stated in the listing.
