Introducing the world-renowned Monk Customs ESG for Wolverine Cat.5 Regulator, the next evolution of the STORM regulator, optimized for reliability, speed, adaptability, and consistent performance across the entire HPA pressure range.

High Grade aluminum alloys are used for this premium Monk Customs product. Strength, durability and precision are at the core of the upgraded design.

The dovetail connection between the upper & lower parts of the grip ensure a tight fit and resistance against impacts.

The Parts on the Monk ESG are interchangeable. The modular design allows you to upgrade in the future or mix and match colors.

With a sleek, ergonomic design and advanced grip technology, Monk ESG seamlessly enhances performance for confident, streamlined gameplay. Because the Cat. 5 regulator is smaller, the ESG design also fits perfectly.

Monk Customs ESG is made to evolve — The Cat.5 version is a testament to that flexibility. Whether you need the whole sports grip or just the part that houses the regulator, Monk Customs has you covered!

The new Monk Customs Cat. 5 interchangable regulator housing has an updated design, with screw-on, low-profile tournament lock.
