Precision CNC-machined from high-grade aluminum, the Maple Leaf M1911/MEU hop-up chamber assembly is a major structural upgrade designed to eliminate barrel wobble, fix hop-up arm flex, and optimize air sealing. Built for Tokyo Marui, KJW, and WE-tech 1911 single-stack GBB platforms, it features an upgraded steel pressure lever paired with Maple Leaf’s signature I-Key tensioner to apply perfectly centered downforce onto the hop bucking. The rigid housing enhances feeding consistency and preserves compression efficiency across cold weather and high-cadence skirmish use.

Includes: CNC Hop-Up Chamber Housing, Heavy-Duty Steel Pressure Lever, and Maple Leaf I-Key tensioner plate.
