Griffin Armament EZ-LOK QD Piston for Pistol Suppressors Stainless Steel

The Griffin Armament EZ-LOK QD Piston is comprised of two parts, the piston, and the barrel adapter.  The piston is the 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.

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.
