Great blast shield
This coupled to your favorite muzzle device makes CQB a blast but towards the target. Driving sound and blast away from the shooter with the capacity to handle up to 9 mm is a wonderful thing.
The 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.
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. An ACME thread, provides speed and ease of 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 pressed stainless steel splined 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 teeth (or splines) which ensure the blast shield will not come off inadvertently. The muzzle device integrates 60 machined anti-rotation grooves which is 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 provides 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. 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. Every time the operator attaches the blast shield, they will articulate the collar to this same locking position.
The patent pending flash hiding end cap features high performance external flash reducing features as well as optimally tuned gas vents that enhance flash reduction while increases flow through performance.
Especially effective on short barrels, the unique design of the DUAL-LOK™ Blast Shield directs concussive force forward allowing an end user to rapidly reconfigure muzzle device function. Ultra strong 17-4PH stainless steel and laser welded construction provides a robust material and build method to withstand intense use and full auto fire without fear of failure.
Melonite QPQ surface treatment provides an extremely hard, durable, and attractive finish.
The Griffin DUAL-LOK™ Blast Shield is compatible with our line of DUAL-LOK™ Mounts up to 9mm (not compatible with PSR DUAL-LOK™ mounts).
Griffin Armament has continued to pursue product development that will enhance hearing safety in tactical and shooting sport situations. The DUAL-LOK™ Blast Shield is a great product for those that would like to reduce the concussion of their muzzle devices.
Compatible with projectiles up to 9mm.

Perfection.
Tones everything down and reduces flash. The dual-lok system is phenomenal. No wear parts and no chance of coming off.
I have not yet had a chance to test fire with this shield, it is mounted on an ARAK-21 12.5inch barreled pistol. I will update once I fire it! I will start by saying you WILL NOT FIND a better looking and more asteticlly pleasing blast shield than this! As with the flash hider I purchased to mount this, the finish and machine work is absolutely impeccable! I cannot wait until they get the HUB threaded version available to go with my key-mo mounts! I was also pleased that it did not take as much twists to thread this thing on as I was expecting. It is fairly quick on and off, and I really like that it has two directions to lock the collar into place so it's always got one position that fully engaged the teeth of the brake/flash hider that you choose for it. Would recommend both this unit and the dual-lok adapters if you like the idea of having a lockable shield or muzzle device.
The 3 pronged paired with this blast shield are amazing. The 3 pronged does well at hiding flash, but with the blast shield the flash is minimized down to an inch and half or 2 inch muzzle flash, straight forward. The way it attaches to the muzzle device is rock solid and won't budge whatsoever. Both are great muzzle devices. I did notice a little more recoil with the blast shield on but with 556 it's hardly noticeable anyways, you'll only really notice it if your actually trying to.
Looks great when installed. Does exactly what it's supposed to, throws all gas and sound down range. Great temporary device while you wait for your suppressor, or full-time muzzle device if you live in California like myself.
Highest quality craftsmanship and metalworking. I unfortunately don’t have the correct dual-Lock muzzle device so have not tried it yet.
Excellent fit & finish. Looks awesome in my SBR. I think I can recommend it 100%.
