The 5/8×24 and 13.5x1mm LH versions have a cylindrical machined extension added to the mount. The 13.5mm version has flats for a wrench on that cylinder extension and has the O-ring interface typical of 13.5×1 LH mounts. The other 3 Lugs are the smaller version pictured.

The 5/8×24 is meant to provide a 3 Lug mount to 30 caliber barrels but is also compatible to 9mm barrels where that thread is uncommonly used. Most 30 caliber barrels are threaded 5/8×24 thread pitch.

1/2×28 Thread Total Length: 1.4375″. Based off of industry standard .625″ barrel threads, added length should be ~.8125″.
5/8×24 Thread Total Length: 2.125″. Based off of industry standard .625″ barrel threads, added length should be ~1.5″.

Made from 17-4ph stainless and Melonite QPQ treated.

DUAL-LOK

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.

KEY POINTS :

• Utility patent-pending
• Wear free mounting system, requires no consumable parts
• Taper lock interface ensures security and accuracy
• ACME thread provides speed of attachment
• Locking ring incorporates 3 anti-rotation splines to eliminate inadvertent loosening
• 120 effective positions ensure a rock-solid suppressor mount and provide extremely low POI shift
• 17-4 stainless steel
• Robust wave spring
• 2 Locking positions and a central unlock position
• Nitrided black for increased surface hardness, corrosion, and wear resistance

DUAL-LOK Minimalist Stealth Flash Suppressor

The muzzle device integrates 60 machined mounting position splines, 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 locking positions and ensures a tightly mounted and locked suppressor.  When the suppressor is installed, only one of the two positions will function by allowing the spring to push the locking collar rearward over the splines.

Constructed of 17-4 PH stainless steel, the DUAL-LOK Minimalist Stealth Flash Suppressor has 3 flash suppressing tines which have anti-reasonance features integrated. The Minimalist Stealth Flash Suppressor weighs 2.4 ounces , substantially lighter than that of most competing flash suppressor mounts. The lighter weight reduces suppressor system weight while making the host firearm barrel lighter and more responsive to the shooter. The flash suppressor does not require timing.

KEY POINTS :

• Utility patent pending
• Wear free mounting system, requires no consumable parts
• Anti-Resonance flutes to prevent pinging under fire
• Taper lock interface ensures security and accuracy
• 120 effective positions ensure a rock-solid suppressor mount and provide extremely low POI shift
• Lighter than most market competitive flash suppressor mounts
• 17-4 PH Stainless steel
• Nitrided black for increased surface hardness, corrosion, and wear resistance
• ¾” wrench flats on muzzle devices
• No timing or shims required
