The CAM-LOK™ (Covert Application Mount – Locking) Universal piston system is comprised from two parts, the piston, 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 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 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 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 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. 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. This product is not intended for use on any fixed barrel firearm aside from 22LR.
Use of the CAM-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.
*NOTE* “1/2×28 special“ is intended for compact 9mm pistols which generally have smaller outside diameter barrels and thus no typical thread shoulder. Examples are : Sig P365, Glock 43. Glock 48… etc. Users with mid to full size handguns should choose the standard “1/2×28” size.
