Griffin Armament EZ-LOK Pistons | Tilt Barrel Pistols

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 piston (bronze color part that is installed in the suppressor). 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 faster and more secure mounting solution on browning style action (tilt barrel) 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 legacy direct thread piston 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™ system supports a 3/4″ socket wrench for installation with prevailing torque, and features a sealing alignment taper, which encourages secure attachment, despite the piston still actuating fore 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 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 EZ-LOK™ pistons are “universal”; accommodating any pistol mounted with an 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 piston models.

The Griffin model EZ-LOK™ pistons are compatible for use with the Revolution®, Resistance®, Optimus® 9mm, and Bushwhacker® 46 in the pistol configurations.

It is important to intermittently clean and lubricate the exterior of the piston and interior of the booster housing to ensure smooth reciprocation with the O-ring in the piston retainer. O-Rings should be replaced intermittently when worn to ensure alignment of the silencer with the booster assembly. Failure to replace damaged or worn O-rings could result in a baffle strike or damage to the piston components. Pistons are H900 heat treated and coated with a rust inhibiting lubricant. Please note, color and color pattern will vary due to the heat treatment.

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 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.

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.

Use of the EZ-LOK® system with a fixed spacer on a fixed barrel firearm will cause damage to the suppressor.  This is for use on handguns with tilt barrel pistols only such as Glock, HK, SIG, 1911, S&W M&P….etc.   A fixed firearm would be a 9mm carbine (PCC), a bolt action, etc.
