Description
Specification

More gas, more punch

The Maple Leaf Monster Valve is a high-flow output valve that replaces the standard release valve in your GBB pistol magazine. By letting more gas through on each shot, it lifts muzzle velocity and gives a noticeably snappier slide and recoil.

Fits the G-series family

It is designed for G-series (Glock pattern) magazines from Tokyo Marui, WE, VFC and Stark Arms, with some fitment across AAP-01 family mags. Check your magazine pattern before ordering.

Built to last

Machined from brass and stainless steel with rubber O-rings for sealing, the valve is made to handle the higher flow it delivers without leaking.

A quick performance mod

Swapping the valve takes minutes with a valve key. Bear in mind the extra flow means higher gas use, so keep a spare bottle handy from our BBs, gas and batteries range.

Bought from the specialists: our in-house workshop in Rochester, Kent can service, repair and upgrade your kit. See our airsoft gun repair and servicing.
