Detailed Product Description

Griffin Armament is proud to introduce DUAL-LOK®, our newest QD mounting system for rifle suppressors. The DUAL-LOK® system is comprised from two parts, the DUAL-LOK® Mount and the DUAL-LOK® muzzle device (of your choice). This page is for the DUAL-LOK® Stealth Flash Suppressor (2.75″).

The muzzle device integrates 60 machined mounting position grooves, which is doubled by the mount’s two locking positions, hence the double entendre DUAL-LOK®. How is this achieved? The mounts’ two locking positions are machined out of phase of one another by 3 degrees which provides the 120 effective locking positions and ensures a tightly mounted and locked suppressor. When the suppressor is installed, only one of the two positions will generally function by allowing the spring to push the locking collar rearward over the splines.

Time intensive R&D resulted in a high performance 3 prong flash hider with incredible resonance reduction. These suppress flash extremely well and do not ring or ping when fired, hence “stealth”. CNC Machined of heat treated 17-4 ph stainless steel material and PVD DLC coating ensures durable, corrosion free service life.

From our research contacting bona fide barrel manufacturers, this device will get Rosco’s 13.7″ barrels (true length being 13.882″) as well as Faxon’s 13.9″ barrels (true length being 14.025″) to the required 16″ minimum legal length. This device was designed to take Rosco’s 13.882″ to 16.02″.

Unfortunately, some of the companies we contacted for exact barrel measurements on their advertised 13.7″ barrels failed to get back to us or refused to disclose the true barrel length for verification. For this device to get your advertised 13.7″ barrel to the required 16″, the barrel must be a minimum of 13.882″ true length (assuming an industry standard 0.625″ threading interface).
