Griffin Armament is proud to introduce DUAL-LOK™, our newest QD mounting system for rifle suppressors. The DUAL-LOK™ system is comprised from two components, the DUAL-LOK™ Mount or equipped suppressor and the DUAL-LOK™ muzzle device (of your choice). This page is for the DUAL-LOK™ 1.2875x24 Mount Interface

A quality QD system should be accurate, robust, reliable, require minimal training, and be free of wear prone metal on metal teeth or ratchets, thereby guaranteeing a longer trouble free service life with minimal maintenance needed. Griffin’s DUAL-LOK™ QD mounting system was designed around these objectives.

What makes this mounting system unique?  It is a combination of desirable mechanical features and performance characteristics in a lightweight, compact system.  DUAL-LOK™ combines a precision, sealing, and alignment taper interface with a stub ACME thread, and provides ease of secure attachment. A robust wave spring provides a reliable and positive heat-resistant spring action to the redundant locking collar (second locking feature).  The locking collar is semi permanently installed to the mount via factory press slpined, stainless steel, taper pins.  Since the mount has no wear prone metal on metal sliding actions like many other mounts, there is no need for the operator to disassemble the system.  This locking ring includes three anti-rotation splines which ensure the suppressor will not come off inadvertently.  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.

Substantial efforts are taken in the manufacturing and inspection of the DUAL-LOK™ products to ensure Griffin customers are outfitted with the best QD mounting systems available.

    Does what it’s supposed to

    This hub has been great. I grabbed two of them and a few muzzle devices. The hub looks great, nice finish and threads were clean. I mounted it up on a can and it engages with the muzzle devices perfectly. My supressors have been locked up solid and no issues with keeping the bore concentric to the suppressor. The hub is easy to take on and off for switching weapons. Overall it looks great and does exactly what it is supposed to do. I am happy with it.

    This mount is excellent when used with the DUAL-LOK Paladin Brake
