Get more from your Hi-Capa

Time to get more range and consistency from your WE, Tokyo Marui or KJ Works Hi-Capa gas blowback pistol. This Maple Leaf hop-up chamber replaces the tired factory unit with a precision-machined upgrade built for skirmishers and target shooters alike.

Full metal build with upgraded hop arm

The chamber is a full metal unit supplied with an upgraded hop arm and an I-key for accurate adjustment. The tighter tolerances create a better seal between the nozzle and bucking, giving a wider, more usable hop range.

Say goodbye to hop drift

Worn factory chambers are notorious for hop settings that wander shot to shot. The improved fit here holds your adjustment where you set it, so your BBs fly true round after round.

Finish the job

Note that the hop bucking and adjustment winding wheel are sold separately, so pick up a matching Maple Leaf bucking to complete the build. Browse more tuning parts in our airsoft accessories range, or book our Kent airsoft techs to fit it for you.

Frequently asked questions

Which pistols does this chamber fit?

It is designed for WE, Tokyo Marui and KJ Works Hi-Capa series gas blowback airsoft pistols. Fitment matches the standard Hi-Capa 1911 platform.

What is included in the box?

You get the full metal hop chamber with its hop adjustment arm and an I-key. The hop bucking and adjustment winding wheel are sold separately.

Why upgrade from the stock chamber?

The tighter tolerances give a better seal between the nozzle and bucking, which widens the usable hop range and helps eliminate the adjustment wandering that plagues worn factory chambers.

Do I need any other parts to finish the build?

To complete the setup you will need a hop bucking and an adjustment winding wheel, which are not supplied. Pairing with a Maple Leaf bucking gives the best results.

Will this improve my range and accuracy?

A better air seal and more precise hop application typically improve consistency, range and grouping, especially when combined with a quality bucking and inner barrel.
