Griffin Armament Dual-Lok Blast Shield

<p>DUAL-LOK™ Blast Shield was designed to offer significant concussion reduction for the end user and other team members operating in the immediate vicinity. Often team members in CQB environments experience concussion from muzzle blast that is not only deafeningly loud but also can cause prolonged headaches that can last for days afterwards.</p><p><br></p><p>The DUAL-LOK™ mounting system is machined into the blast shield body, for maximum accuracy and durability. It features a precision taper interface (one locking feature) between the mount and the device ensuring accuracy and repeatable POI shift.&nbsp;An ACME thread provides speed and ease of attachment.&nbsp;A robust wave spring provides a reliable and positive heat-resistant spring action to the redundant locking collar (second locking feature).&nbsp;The locking collar is semi-permanently installed to the mount via factory-pressed stainless steel splined taper pins.&nbsp;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.&nbsp;This locking ring includes three anti-rotation teeth (or splines) which ensure the blast shield will not come off inadvertently.&nbsp;The muzzle device integrates 60 machined anti-rotation grooves which are doubled by the collar’s two locking positions. How is this achieved? The collar’s two locking positions are machined out of phase of one another by 3 degrees which provide the system with 120 different locations to lock and ensures that when the blast shield is firmly screwed onto the taper a locking spline will be at an ideal location to ensure a rigid and locked blast shield.&nbsp;When the blast shield is firmly attached, only one of the two lock positions will work, allowing the spring to push the locking collar rearward over the splines.&nbsp;Every time the operator attaches the blast shield, they will articulate the collar to this same locking position.</p>
