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 magazine 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.
Note: CAM-LOK® is designed to be a covert, QD silencer attachment method, and should not be perceived as an active-locking system. CAM-LOK® should be check-tightened each magazine at a minimum. For customers looking for a more traditionally-threaded system with increased retention, we recommend EZ-LOK™ as an alternative.
Features:
*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.
I bought both .45 and 9mm barrel adapters for my rev45. Great quality adapters and easy installation. Torqued to the minimum spec and was good to go. I'm happy with purchasing. And again Griffin has great customer service for sure! Thanks guys !
This adapter was worth the money hands down! It made threading my suppressor on super easy with a quarter turn and locked it into place with a snug fit. It was easy to attach to my pistol and tightened up with an adjustable wrench and I had no issues when shooting with it on my pistol with or with out the suppressor attached.
Great way to give you the universal ability to move your .45 can to multiple caliber hosts very quickly without changing pistons because the threads on the adapter are a universal size. I’m so happy with this ingenious invention.
Very ingenious device! Keep it going.
Fit, and function work like a champ... The fact you only need ONE piston... And just add cam locks is a spectacular idea!!
Great product that mitigates the suppressor from walking off the barrel during use. I like the fact that I don't have to worry about retightening the suppressor to the host firearm. I really like the ease of switching a suppressor among multiple handguns too! Props to Griffin Armament for utilizing a tried and true firearm design. The Russians knew what they were doing with the PB. Way to keep it going! Dope stickers too!
This system is excellent for a realistic way of carrying and quickly attaching your suppressor across multiple platforms. I think it would be amazing if the cam lock system could be cut directly to a barrel utilizing the cam system without having the cons of the adapter.
Really nice pieces of kit, well made, and nice looking to boot. Terrific finish…reminds me in the nDLC on the Gen 5 Glock slides. Love this CAM-LOK platform. Keep it up, Griffin!
Well made product. Allows for very quick and secure suppressor installation.
Ordered a cam-lok for my 1911 and am very satisfied. Only takes gentle twist and a slight snug to secure my B46. Ordered a second one for my son's 1911 so we can both enjoy!
