Description

The CAM-LOK® (Covert Application Mount - Locking) Universal piston system is comprised from two parts, the piston or CAM-LOK® direct thread adapter, and the barrel adapter.  This product page is for the barrel adapter (smaller black component pictured). 

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 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® interface supports a 3/4" socket wrench for installation with prevailing torque, and features a taper locking system, which encourages secure attachment, despite the piston still actuating for and aft during the firing sequence.  The piston or CAM-LOK® direct thread adapter 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 and CAM-LOK® direct thread adapters 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 piston is "universal"; accommodating any pistol mounted with a 3 Lug universal 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® QD barrel adapters between CAM-LOK® piston models. This adapter also acts as a thread protector for the more expensive barrel's threads which when used with fixed pistons, are traditionally exposed. 

 9mm versions are shorter  .45 caliber versions feature an extended cylinder to attach to the larger diameter barrels. 

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.

*NOTE*   "1/2x28 special" is intended for compact 9mm pistols which generally have smaller outside diameter barrels and thus no typical thread shoulder.  Examples are : Sig P365, Glock 43. Glock 48... etc.   Users with mid to full size handguns should choose the standard "1/2x28" size

FOR FIXED BARREL APPLICATIONS (PISTOL CALIBERS ONLY)  : This can be accomplished using one of our CAM-LOK® direct thread adapters, in conjunction with a CAM-LOK® barrel adapter.

Glock Gen 4 or Gen 5 users: It is reported the barrel adapter may touch your guide rod when the slide reciprocates. We have not been able to replicate in house using CAM-LOK®/EZ-LOK™ barrel adapters with Glock Gen 4/5 recoil spring assemblies. However, the items below allow your Glock® Gen 4/5 to work with a Glock® Gen 3 recoil spring assembly that does not have this reported issue.

    1/2x28 Cam-lok

    Published by JT on 10th Jan 2023

    I am using the cam-lock system with the 1/2x28 direct thread on my 22 suppressor. This has given me a quick attachment that I have always wanted for it my 22lrs. Works pretty much like a 3 lug but without the spring to over come. Super quick and repeatable which is super nice for POI. Very happy with the system. The brakes fit standard length 1/2x28 threads on the 3 different barrels I used them on. No need for a spacer or shims.

    9mm camlock adapter

    Published by john Wood on 13th Dec 2022

    The product seems well made , it installed easily and worked well. The lock up itself was very good , I did not encounter the loosening that some people say they have after 250 rounds.
    The only reason I gave it a 4 was having to order it and wait to use my supressor , I have the optimus which the piston adapter was made for the cam lock.
    other than that I would highly recommend this company and their products as a whole .

    Tight But Solid Fit

    Published by Thomas Guerra on 5th Dec 2022

    I ordered two of these off the rip, one 45 cal and one 9mm. I've only put the 45 cal adapter on my 1911 so far but from that experience, I have high hopes for the 9mm. To start, the finish looks great and holds up to the mounting and torque process. The scuffs that occurred wiped right off. Next, the fit. The threads are tight on this one. Almost to the point I thought I was cross threading it when trying to hand screw it on. I have a thread protector that mounts easy so "forcing" this adapter on was a little unsettling. BUT, no cross threading occurred and to be safe, I would thread it on and back it off a little at a time until it was all the way the on so there was binding of the threads. Even before torquing, I had absolutely no worries about this coming loose.

    Worth the money

    Published by Gibbs on 13th Oct 2022

    Called and spoke to someone (a real human in less than a minute) who recommended the cam lock and direct thread adaptor for use on a pcc. Install was simple and have shot about 100 rounds suppressed so far with no issue.

    My only “gripe” would be no option for expedited shipping.

    Must have

    Published by Jimmy Wusinich on 17th Aug 2022

    I have now 2 of these badboys, I highly recommend using thread sealer also from Griffin Armament. Came loose a few times because I didn’t tighten it enough , I’ll be buying more of these in the near future most definitely. Another success from Griffin Armament. I salute you Griffinights!!!
