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. 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.

NOTE
1/2×28: 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).
1/2×28 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 1/2×28 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.
1/2×28 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.

The 9MM QD Piston Barrel Adapter fits well with the QD Piston , very easy to attach the silencer

I already reviewed the piston part of this system and in short, I love the whole thing. As mentioned, the only downside is the cost of these adapters, but innovation and design aren’t cheap and I understand that so I’m willing to pay for them. To properly torque these onto your barrel, make sure you have a deep well 3/4” socket. You could get by with an open ended or crescent wrench, but you run the risk of marring the flats on the device. A socket will help prevent that and help establish proper torque.
I am concerned about the tri-lug threads and the device taper being exposed all the time when unsuppressed, but I’m not throwing my guns around like an animal so I don’t think that’s too much to worry about. I would recommend investing in this system if you like shooting multiple pistols suppressed at a time and if you hate having to smoke your direct thread cans on to make sure they’re tight. Basically, buy this and you won’t be disappointed.

I ended up buying the 9mm and the 45 ACP version with the Cam Lok Piston. Great design, EASY TO USE!
Alan –
This cam-lok barrel adapter worked great. You have to get the piston that corresponds with the suppressor you are using. Let me tell you these two products work great. With utilizing the corse thread in conjunction with the taper lock between the two parts the suppressor doesn’t move. Screw it down the half of a turn and it is locked on. No amount of shooting on my Glock 19, Archon Type B, CZ P01 did it ever start to back off the threads like a typical direct thread does. This is a great product!! Thank you Griffin for inventing such a wonderful product.
Talbert Frazer –
Buy this and the piston you know you want it and it is freaking awesome.
Bill Poynter –
I just wrote a great review of the cam lock piston and adapter. I can’t say enough good about this system. Its so good, I am selling my old pistons because I will never use them again.
Steven Pinson –
Quality is first rate! Torqued to twenty foot-lbs as directed. Installed easy enough but I seem to have a drastic POI shift compared against the thread on piston previously used in my Revo 45 can … jury is out.
Sean P –
These are great. Move your suppressor from one gun to the other. Tight lock up and you don’t have to worry about it coming lose.
Chuck –
These are great for Quick on and off for my B&T P320 very fast on and off and repeatable POI impact

The piston and the adapter mount up nicely. With mine if you jam the adapter into the piston all the way you have to back it out about 1/2mm before it will turn and lock into place. It’s extremely secure and makes life nice. No need to muscle the can on and no need to constantly tighten. Swapping a suppressor among several hosts is a breeze. I can now use an OEM barrel for my Sig instead of a 3rd party one that came in 1/2 x 28. Instead of shopping for one off parts to make things ‘compatible’ you can just put on an adapter and go about your business.

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!
Raphael Cohen –
Well made product. Allows for very quick and secure suppressor installation.
GSR Shooting Supply –
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!
Mac Mcmullen –
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.
James –
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!
Carl –
Fit, and function work like a champ… The fact you only need ONE piston… And just add cam locks is a spectacular idea!!
Luis –
Very ingenious device!
Keep it going.
Jason Henley –
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.
Jacob Stierhoff –
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.
Dustin Smith –
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 !

The 1/2×28 special barrel adapter worked as advertised & fit perfectly on my hellcat RDP. Awesome product , with genuine customer service! They also surprised me with some pretty rad stickers, would definitely recommend to a friend.
Steve –
Quality is excellent. The only reason I didn’t offer 5 stars is that it isn’t offered in a stainless finish. Many firearms are manufactured with SS barrels and a stainless muzzle device would look better.
RW Higgins –
This was suggested to me by a good friend. This is a great idea and extremely well executed.
CJ –
Having what essentially amounts to a “three lug” style system for pistols is fantastic. The system is incredibly secure when affixed properly. Easy to install and easy to use. The 1/2×28 is super low profile but the 13.5×1 LH adds a little length (similar to how the .45 looks) but I’m sure there’s a reason for it. I’m a big fan of the system. I think thread protectors would be a nice addition, but I suppose the coarse “three lug” threads are more robust and less likely to be dinged, but still.
Michel Guichard –
The adapters are well-made they lock up with my suppressor, but I have not made it to the range yet
Nathan Puffenbarger –
Just like Griffin’s Suppressors, High Quality Everything! Love your products and company.

Bought to use for QD mounting a .22LR silencer. The CAM-Lok system is a good update to the hundred plus year old interrupted thread technique.
Vance L –
Both adapters are well made & a perfect fit.
Should have torque specs included.
Kerry Kanemitsu –
Called Griffin and they made good on the order. They will be making the claim with FedEx. Great Service.
Marc a south –
A must have for a Bushwacker 46 I can go from one gun to another without changing anything plus I didn’t see any impact shift like you do with some thread ons
Luke –
Love these. One of the best innovations is pistol suppression ever. So quick to attach and remove.
Mike Scarbrough –
I am absolutely impressed with Griffin Armament products the locking system is super fast and easy to operate. a giant thumbs up
John –
Shipping is fast, part has a very nice finish threads on barrel nice. Over all nothing to complain about.
Sal V –
Great amazing product simplified process of removing host to mount. Makes your system function like a 3 lug system for hand guns.
A Smith –
Total game changer and wish I would have come across these sooner. Much faster than direct thread and smooth to attach. only wish there was a smooth protector available for them. Catches a bit on my holster when not running suppressed.
Robert Williams –
Best Customer Service Ever
Damon –
Cam lock 45 acp and 9mm. Both are high quality and design
Ben P –
Took the cam lok system installed on my HK 45 tactical and paired it with a rugged obsidian 45.200 rounds and never even had to check the suppressor. Will be ordering more barrel adapters for sure! Simply the best for pistol setups
Bob B. –
This was the best add on for my suppressor host. Switching host has been a bit of a pain. Checking for walk off has been a pain. No pain since I equipped my host with the CAM-LOCK.
Jeff Rodeman –
I always hated when a suppressor would walk-off the barrel with a direct thread attachment. This makes attachment and detachment of the suppressor super easy and fast, just like in the movies, when paired with the GA Cam-Lok booster piston. This is my 3rd one and love the ease and security of moving from one pistol to the next. So glad I went with this system.

Suppressor revolution 45
calibers tested 9MM / 38 super/ 40 Smith Wesson/ 45ACP
product tested cam-lok
Target set at 15 yds
reliability test
I loaded two magazines for each firearm had a oven Mitt with me and was gonna switch the suppressor after each mag. The ease that I went from one firearm to the other was absolutely incredible I went through all eight magazines of different calibers with no failures also the POI was is extremely minimal. I waited an hour and repeated the test with the same results, the engineers that developed this deserve a day off !!
Dave –
This is a very good quality adapter enabling me to use the Optimus 9 on my Sig P320. Ordering it was easy and it shipped immediately.
James Wusinich –
Best device I’ve ever purchased for my suppressors. Easy to install, easy to pay the fair price for something that works efficiently and effectively. I have a deep love for Griffin Armament. I’ve purchased their barrels, AR parts, AR uppers, muzzle devices , , suppressors, Iron sites, you name it. When it comes to buying from this company, I do it with pure confidence. Top tier quality products from genius imagination. I need a new T-shirt from them, my x stole mine. If I ever have a kid his or her name will be Griffin Armament. Thank you Griffin armament staff for answering all my dumb questions and providing a variety of successful products that keeps me sincerely excited for what comes out next. Cheers to the Griffin.
James Martinez –
Great quality finish was good very easy to use great investment
Jimmy Wusinich –
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!!!
