Description

The CAM-LOK® (Covert Application Mount - Locking) is a universal QD piston system comprised of two parts, the piston, and the barrel adapter.  This product page is for the piston (bronze color part that is installed in the suppressor). 

The Griffin Armament CAM-LOK® interface affords the user the ability to convert the suppressor to a much faster and more secure mounting solution on browning style action (tilt barrel) pistols vs it's legacy technology, single piece, direct thread piston counterparts.  This system provides a rapid, secure attachment to the host pistol.  Direct thread single piece pistons have several negative attributes.  They do not accept tools, and are hand tightened to the host firearm. As a result of hand installation, they loosen when the piston system reciprocates under slide cycling during the firing sequence.  This vibration and inadvertent loosening of pistol silencers, requires end users to constantly check tighten pistol silencers.  This periodically causes users to have "bad range days" with unforeseen baffle strikes and end cap strikes.  These unfortunate events cause logistically burdensome work for consumers to communicate with service departments, ship products back and forth, and sometimes assume charges for repair for these issues.  

No longer do users need to worry about their pistol suppressors loosening during use (as with traditional fixed direct thread pistons).  The CAM-LOK® system supports a 3/4" socket wrench for installation with prevailing torque, and features a taper lock system, which encourages secure attachment, despite the piston still actuating for and aft during the firing sequence.  The piston can be attached / detached in any one of three, 120 degree positions, ensuring there are no "false positive" interfacing positions to slow deployment of the suppressor onto the host firearm.  Additionally, the manufacturing accuracy of the interface is held to Griffin Armament's high quality standards for squareness, and concentricity, ensuring that each mounting position has similar and minimal POI shift influence. To support this, the mating pistons have all mating diameters and interfacing geometry qualified in a single operation, for tool quality accuracy and perfection.  A similar manufacturing theory was applied to the barrel adapter for maximum alignment accuracy.  

End users benefit from being able to attach their silencer to various adapter interfaced host firearms, without having to disassemble the suppressor and change the piston to a different thread pitch.  The CAM-LOK® pistons are "universal"; accommodating any pistol mounted with a 3 Lug CAM-LOK® barrel adapter.  Additionally, end users with different brand suppressors supported by the CAM-LOK® piston family, will be able to benefit from the interchangeability of CAM-LOK® barrel adapters between piston models. 

 

These Pistons are required for use with the Revolution®, Resistance®, Optimus® 9mm, and Bushwhacker® 46 in the pistol configurations.  

It is important to intermittently clean and lubricate the exterior of the piston and interior of the booster housing to ensure smooth reciprocation with the O ring in the piston retainer.
O-Rings should be replaced intermittently when worn to ensure alignment of the silencer with the booster assembly. Failure to replace damaged or worn O-rings could result in a baffle strike or damage to the piston components.

Piston are H900 heat treated with a rust inhibitor. Please note, color and color pattern will vary due to the heat treatment.


Installation & Use Notes  : Suppressor should be tightly assembled when using this product to avoid inadvertent disassembly of the suppressor when removing it from QD barrel adapter. Barrel adapters should be installed to their host firearms with a minimum torque rating of 20 ft/lbs using a 3/4 socket and needle type torque wrench.  Use of a box end wrench will not have optimal contact with the wrench flat geometry on the adapter and may damage the adapter.

Use of the CAM-LOK® system with a fixed spacer on a fixed barrel firearm will cause damage to the suppressor.  This is for use on handguns with tilt barrel pistols only such as Glock, HK, SIG, 1911, S&W M&P....etc.   A fixed firearm would be a 9mm carbine (PCC), a bolt action, etc.

    Works as advertised. I was pleased and surprised at how easy it is to use. I have ordered another and a couple more barrel mounts.

    This is the way

    Published by Kenny on 17th Mar 2022

    I've had my Optimus 9 for 3 years. This is by far the best way to install and shoot suppressed pistols.

    The best decision

    Published by Mystery Me on 30th Jan 2022

    Needed an alternative on the discontinued AAC Tirant 45 pistons. Searched and found Griffin Armament . Ordered the Cam-lok and piston. Perfect fit flawless installation, can’t be more pleased with my choice I ordered 3 more cam-lok systems . The ability to interchange between multiple handguns is amazing . So glad I found them and hope y’all will make the decision to buy as well.

    Cam-Lok piston

    Published by Rodey on 28th Jan 2022

    Was a bit nervous about mixing different companies parts but this fit my Dead Air perfectly. In conjunction with the Cam-Lok barrel adapter this provides a simple, tight and secure connect of the suppressor to the pistol. Fired about 50 rounds and the suppressor was as secure after firing as it was when installed. Also bought the Cam-Lok compensator to protect the barrel adapter. Haven’t fired it with it on but it adds a nice look in comparison to the plain barrel adapter.

    True innovation

    Published by Mike on 20th Aug 2021

    These mounts/pistons from griffin are truly a step forward in the pistol mounted silencer world. Gone are the days of having to check your can every mag while shooting. The only con I can see is the mount has to be removed from your pistol barrel if you want to clean your gun. It’s awesome that griffin is making pistons for other brands, that makes this system something that can actually be used and makes shooting pistol cans of any brand far more enjoyable! Kudos griffin

    Fantastic Product

    Published by Matt B on 21st Jul 2021

    I purchased the Cam-Lok QD system for a handful of handguns. This prevents you from having to switch pistons when changing firearms and is worth its weight in gold. It works well, but you have to make sure you tighten firmly otherwise the suppressor can come loose. When it does happen, it is obvious though.
