The SOLGW NOX-9 muzzle device is THE answer for getting your 13.7" barrel up over 16", while simultaneously enabling mounting any Keymount compatible suppressor.
The QPQ treated muzzle device features THREE sets of ports designed to time for right AND left hand use, venting at 12 o'clock, 9 o'clock, and 3 o'clock.
Forward of those ports are the signature trio of open tines, maximizing flash reduction without any unwanted high pitch ringing common with other popular open tine flash-hiders.
Shims are included with this 1/2x28mm muzzle device, and it is pre-drilled for pinning and welding to any barrel 13.7" or longer to bring it up over 16" in length.
