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. We recommend to check suppressor tightness every 2-3 magazines to ensure it has not worked loose due to vibration caused by the cycling of the slide. 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.

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

*NOTE*

1/2x28: Indexes off the barrel shoulder. For use on standard, sub compact, compact, and full-size tilt-barrel firearms that have a normal profile of barrel (G19, G17, P320, S&W M&P 2.0).

1/2x28 Special: Indexes off the face of the muzzle. For use on micro compact tilt barrel firearms with little to no barrel shoulder due to the thinner profile of the barrel (G43, G43x, G48, P365, P365XL, Hellcat).

 If you are concerned about fitment, the 1/2x28 special will work on a normal profile barrel as well. It will operate the same, but if you have a longer threaded surface on your barrel, you may see uncovered threads rearward of the muzzle device when using this option.

1/2x28 SMG/PCC: Made specifically for SMG’s and PCC’s (Sub Machine Guns and Pistol Caliber Carbines) that have the industry standard length of threads commonly found on carbines: 0.625.”

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.

    Worked out perfect, if you are a first time rookie I would suggest calling to get an assist from the experts at Griffin. Too many choices

    Cam Lok Barrel Adapter

    Published by Phillip Brockwell on 9th May 2024

    Probably the most innovative product on the suppressor market, it’s so much more convenient and robust than traditional threading. Plus, it serves to protect the fine threads of your somewhat expensive barrel.

    Fitment

    Published by Tait on 7th May 2024

    Received cam-lok for the 9 mm and fits beautifully. Just waiting on suppressor background to pass test fitment but I’m sure that will be great. Very happy with product.

    Awesome Cam Lok Barrel Adapters

    Published by Jim on 15th Apr 2024

    I purchased a few of these and placed on different firearms. Very fast in switching suppressor to different firearms. Locks tight and performs great! Awesome product.

    Great product, fills a hole in the market

    Published by John on 11th Apr 2024

    I've had CAM-LOK adapters for a 9mm can and gun for some time and recently just purchased an adapter for a .22 can and 4 barrel adapters for multiple guns. This is a product that fills a significant gap in the market IMO, particularly when many people only own 1 can per caliber or at least far fewer silencers than firearms. It turns thread on into QD without any loss of POI shift. I do recommend using something whether a paint pen or scribe to mark the can so you always attach it radially in the same way, since there's likely always some runout between the can, adapters, and barrel threads. If you always attach the can the same way, the POI shift is consistent and predictable. One of my favorite and most useful Griffin products.
