Emissary Development Handbrake X M-LOK – Ergonomic Handstop

The Emissary Development Handbrake X M-LOK is a premium, next-generation ergonomic handstop designed for M-LOK compatible rifle handguards. Building upon the success of the original Emissary Handbrake, the Handbrake X introduces improved ergonomics, reinforced construction and an integrated rubberized grip surface.

Featuring a distinctive forward-swept angle, optimized dimensions and tapered sidewalls, the Handbrake X provides a natural, comfortable contact surface across different shooting styles.

Its proprietary textured rubber inlay enhances grip comfort, while the integrated anti-slip bottom ledge helps prevent unwanted hand movement. Built-in front and rear barricade stops provide additional contact surfaces for stability.

Manufactured in the USA using advanced multi-stage injection molding technology, the Handbrake X combines glass-filled polymer with a rubber grip insert for excellent durability and lightweight performance.
