Griffin Armament DUAL-LOK HUB MOUNT INTERFACE - A92F85D1 GFN. 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 HUB Mount a 1.375x24 threaded 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 yet compact system. DUAL-LOK has great potential for widespread product application. A precision taper interface (one locking feature) between the mount and the device ensures accuracy. An ACME thread provides speed and ease of attachment. A robust 17-7 Wave spring (718 inconel on integrated mount Griffin suppressors) 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 pressed grooved 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.
