Frequently Asked Questions

Need To know more?

Will These Parts Fit My Hi-Capa Clone?

Most parts in this collection are designed for the Tokyo Marui Hi-Capa. Many clones follow the same design, but tolerances vary between manufacturers, so some parts may need fitting or may not be compatible. Check each listing and contact us if you're unsure.

What Is a TDC Hop-Up Chamber?

A TDC hop-up chamber lets you adjust the hop-up setting without fully stripping your pistol, so you can fine-tune it quickly for different BB weights and conditions.

What Should I Upgrade First on a Hi-Capa?

For most players, a TDC hop chamber with a quality hop rubber and inner barrel gives the biggest improvement in accuracy. If you want snappier cycling, an aluminium blowback unit and an enhanced loading nozzle are popular next steps.

Hi-Capa Upgrades

Tokyo Marui's Hi-Capa is a gas blowback pistol inspired by double-stack 2011-style designs, and it has become one of the most customised pistol platforms in airsoft. With a wide choice of aftermarket parts, you can tune it for faster cycling, better gas efficiency, sharper accuracy or a completely new look.

Accuracy upgrades

A TDC hop-up chamber lets you adjust the hop-up without stripping the pistol, making it quick to dial in for different BB weights. Pair it with a quality inner barrel and hop rubber from our hop units and rubbers range.

Cycling and reliability

CNC blowback units, enhanced loading nozzles, short-stroke buffers and uprated recoil springs can make your Hi-Capa cycle faster and feel snappier, while match-grade stainless steel parts such as slide stops help improve durability under hard use.

Build your own

Slide kits such as the CTM TAC 5.1 Superline give your pistol a striking new profile, and HPA adapters let you run it from a tank via our HPA accessories for consistent performance in any weather.
