AW 3 Port Steel Lite Series 1 have smaller ports so they can be turned down to a smaller diameter (smallest is .800 in).
The AxisWorks Enabler Series 1 lite, 3 port muzzle brake is designed to get the job done. During the design, the engineers on staff at AxisWorks have spent countless hours using Computational Fluid Dynamics Software with three main intentions. Reducing recoil, perspective noise levels and maintaining appealing ascetics. The 3 port model has maximized recoil reduction while maintaining a small size. The lite model allows for a streamline design with the barrel for maximum aesthetic value.
Diameter: .800 in – .950 in
Height: 2.05 in
