Gate-LOK™ Closed Tine Flash Hider 5.56mm 1/2x28

The Griffin Armament Gate-LOK™ muzzle devices interface with Gate-LOK™ suppressors (M4SDK, M4SD2, 30SD, and 30SDK) as well as the QD Blast Shield.  Not recommended for use with the GP-NATO suppressor, 1.375-A2 mount interface, or OPTIMUS A2 BLAST SHIELD. 

The Gate-LOK™ Closed Tine Flash Suppressor was designed for a military service branch.  It provides improved flash suppression and rise compensation vs the A2 flash suppressor, especially on short barrels, and retains Bayonet, Bore sight collimator, and blank firing adapter functionality.  The stop washer was integrated into this mount, such that that component is no longer required for optimal interfacing of our Gate-LOK™ suppressors.  A 3-position wire cutter was added to the front of the unit, to support breaching hasp locks and wire obstacles as well as the clearing of urban concrete loopholes (clearing rebar after using a sledgehammer).  CNC machined from a solid bar of heat treated 17-4ph stainless steel, the Gate-LOK™ Closed Tine Flash Suppressor is built to last.

Includes 1/2x28 shim set
