The Griffin Armament EZ-LOK Suppressor Mount Interface affords the user the ability to convert the suppressor to a much faster and more secure mounting solution on fixed barrel pistols. The 1.125x28 EZ-LOK Mount Interface can be installed into Griffin pistol suppressor booster housings, the Bushwhacker booster housings, and into the Optimus Micro tube body. This single device takes the place of the piston, spring, and piston retainer nut in the Nielsen device. The 1.375x24 EZ-LOK Mount Interface can be installed into the Griffin suppressor tube bodies threaded with the industry HUB pitch (1.375x24). These Griffin suppressors include the Bushwhacker .46, EXPLORR Utility .224 & .300. This device is also compatible with other 1.375x24 threaded suppressors.Features17-4 Stainless Steel H900 treatedQPQ Nitride finish for attractive, durable black finishWrench flats for easy installationInside taper locks direct thread adapter onto barrel adapter
