DUAL-LOK™ SilencerCo® Charlie Mount Interface

This mount interface allows compatibility between SilencerCo® Charlie mount (ie. Saker®, Velos™) suppressors and Griffin DUAL-LOK™ muzzle devices.

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.  The locking collar, spring and Charlie threaded collar are semi permanently installed to the mount via factory press splined, stainless steel, taper pins.  This locking ring includes three anti-rotation splines which engage grooves on the muzzle device, ensuring the suppressor cannot 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 lock 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.
