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. 

Features:

  • CAM-LOK® (Covert Application Mount - Locking) Patented Universal QD piston attachment system
  • 3 mounting positions, 120 degrees separated for rapid mounting
  • Forward taper surface locks in place with interfacing piston and drastically reduces or eliminates common baffle/end cap strikes 
  • Coarse threads are top cut to increase durability and wear resistance
  • 3/4"or 19mm wrench pattern accommodates socket wrench for secure and easy installation 
  • Compatible with Universal QD pistons (sold separately)
  • Compatible with Universal Direct Thread Adapters (sold separately) 
  • Internal bore reduces side concussion and visual disturbance vs blind muzzle
  • Total system weight is identical to legacy direct thread pistons
  • QPQ Nitride finish for attractive, durable black finish
  • 17-4 stainless steel material
  • Also supports Universal Carry Comp

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.

    9/16-24 barrel adapter for .40 S&W

    Published by Dan Jones on 22nd May 2023

    I am very pleased with the quality of this CAM-LOK adapter. The threads are well made and it took the installation torque easily. This is my second one, so now I can move my Bushwhacker 46 directly and quickly from my .45 to my .40. For those who are wondering, the 9/16-24 adapter looks similar to the .45 adapter in the picture, i.e., it is longer than the 9mm adapter.

    Cam Lok

    Nice addition to FNX 45. Moderate recoil reduction but it works very well. It is better than just a thread protector. Hasn't come loose.

    Cam lok is fantastic

    Published by Michael Davis on 31st Mar 2023

    I love cam lok. These adapters are expensive but once you invest in a cam lok piston and barrel adapter there is no doing it any other way. Just make sure you apply the correct torque of 20 ft/lbs when installing the adapter and it won't come off. There's nothing like adding and removing my suppressor with a simple twist. I love showing people how easy it is at the range. Highly recommended.

    Excellent

    Published by Derek Dienhart on 21st Feb 2023

    I don't think it's possible to design a faster mounting system. Literally just a single turn of the wrist and you're on. It almost doesn't seem secure but rest assured, it is. And once engaged, the suppressor stays locked in until YOU decide to remove it. Just make sure you torque it to spec or your suppressor will take your cam-lok with it.

    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 .
