GFHC KeyMount® Flash Hider

Inspired by the H&K G36 Flash Hider, the JMac Customs™ GFH and GFHC muzzle devices are engineered to reduce muzzle flash and mitigate muzzle rize, enhancing your shooting experience. Crafted from erosion and corrosion resistant 17-4PH stainless steel and coated with a protective satin black nitride finish, these muzzle devices offer longevity and performance, even under rigorous use.

Key Features:

• The GFHC has one shorter slot cut on the bottom functioning as a compensator (C) forcing more gas upward effectively reducing muzzle rise. Due to this feature the GFHC requires timing
• KeyMount® and KeyMicro® Compatible
• Preferred option for several OEM 13.7 and 14.5 pin and weld applications on 5.56/5.45
• Pre-Drilled Hole for Pin/Weld

Specifications:

• 17-4
• Nitride
• Hole pre-drilled for pin and weld 

Available in multiple configurations and thread options to suit your specific firearm.

Note: The GFHC model functions as a compensator and requires timing

PROFESSIONAL INSTALLATION RECOMMENDED

• Shouldermount muzzle devices index against the shoulder of the barrel 
• Facemount muzzle devices index against the face of the muzzle and will require a facemount shim kit for timing
• For facemount devices, we recommend the use of an alignment rod for installation by a certified professional to ensure the facemount shims are stacked properly and do not make contact with the projectile exiting the muzzle
• Multiple shims can be used to achieve proper timing
• We recommend 30-40ft/lbs of torque along with Rocksett applied to the threads
• Improper installation may result in damage to the device and/or the suppressor as well as potential injury to the user
