Description

The EZ-LOK™ is our new patent pending, separate eco-system, separately available, simplified, universal Rapid Index™, piston system. EZ-LOK™ is comprised of two parts, the piston, and the barrel adapter. This product page is for the barrel adapter (smaller black component pictured). This product was intended to provide a simple solution with zero training or familiarity requirement for customers. CAM-LOK® is our original and still higher performance, patent pending product in the pistol silencer piston mount product class that Griffin Armament created.

The Griffin Armament EZ-LOK™ interface affords the user the ability to convert the suppressor to a much faster and more secure mounting solution on browning style action (tilt barrel) pistols vs it's legacy technology, single piece, direct thread piston counterparts. 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 EZ-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 can be attached / detached in one single mounting orientation, simplifying the system to something anyone who can screw in a lightbulb can immediately grasp.  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 EZ-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 EZ-LOK™ barrel adapter. Additionally, end users with different brand suppressors supported by the EZ-LOK™ piston family, will be able to benefit from the interchangeability of EZ-LOK™ barrel adapters between EZ-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 barrel adapter. Barrel adapters should be installed to their host firearms with a minimum torque rating of 22 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.

CAM-LOK® requires suppressor attachment with minimum 22inch lbs of force.  EZ-LOK™ requires suppressor attachment with minimum 13.75inch lbs of force.  With both systems, a slight squish should be felt during tightening and indicates tapers are engaged (locked), and required installation torque has been met. 

For the fastest system, choose CAM-LOK®.  For the the most simple system, choose EZ-LOK™.

Features :

  • Patent Pending EZ-LOK™ universal QD piston attachment system
  • 1 Mounting orientation, for simple mounting in approximately 4-5 seconds
  • Internal taper surface locks in place with interfacing barrel adapters and drastically reduces or eliminates common baffle/end cap strikes 
  • Compatible with Universal QD pistons barrel adapters (sold separately)
  • Total system weight is identical to legacy direct thread pistons
  • H900 heat treated for improved durability and wear resistance
  • 17-4 stainless steel material
  • QPQ Nitride finish for attractive, durable black finish

*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.

    EZ=LOK barrel adapter

    Published by John Michelli on 1st Feb 2024

    Works great. Bought this so I can use my Rugged Obsidian 9 on my Dissent 300 BO pistol. I trust Griffin's taper mounts with all my suppressors.

    EZ-Lok Barrel adapter

    Published by John Michelli on 17th Nov 2023

    Works as designed and allowed me to use the EZ-LOK system with my Obsidian 9 so it doesn't unscrew itself.

    A must-have!

    Published by Seth on 14th Nov 2023

    If you want to easily shoot your pistol or PCC with a suppressor, then I highly recommend the Griffin Armament EZ Lok system and adapters. I have a Rugged Obsidian 45 and it’s so much more pleasant to be able to easily move it from one pistol to the other to my PCC. Also, I haven’t noticed any walk-off at all.

    Great product great customer service

    Published by Sherman Robbins on 1st Aug 2023

    I bought 4 of these 2 in 9mm 2 in .45 had an issue with one of the .45 threading on. I emailed customer service on a Sunday night they had another one on the way Monday without me knowing. I had resolved the issue on Sunday night after sending the email something was caught in the threads I took a brass brush and cleaned the treads it screwed on without a problem. After getting the shipping email from customer service I emailed them back and let them know I had resolved the issue and I returned the one they had shipped out.

    FNX 45 T

    Published by Happy Shooter on 3rd Jul 2023

    It works great, but… this doesn’t thread all the way onto an FNX 45 T. I’ve got this on a PDP Pro as well and that threads to the shoulder. This is a few mm off the shoulder.

    EZ-loc

    Published by David Strickland on 28th May 2023

    This thing is great! It’s a taper mount for the handgun. Just another smart innovative products from Griffin. Locks up so much better than direct thread. I can freely and quickly change from 9 mm to 40 on the bushwacker 46 in seconds. I prefer this set up over the cam lock system. Special thanks to Jack Griffin for taking the time to get me straight and answer a few questions I had. Pew, pew ?

    Good solution

    Published by Eric C. on 15th May 2023

    This is a good solution for those with one or two rimfire suppressors but multiple hosts. Many rimfire suppressors have aluminum direct thread connections and these steel adapters can preserve the condition of the suppressor parts.
