Low Profile Direct Thread Mounts

Now available: Low Profile Direct Thread Mounts

The Low Profile Direct Thread Mount allows for less overall length and weight to the suppressor and host firearm. Designed to be rigid, it is cut from 17-4 Stainless Steel and then heat treated to 190,000 PSI tensile strength and 47 Rc hardness. It is one tough and concentric mount. It adds only 0.080″ to your suppressor. Works with any suppressor with the de facto standard 1.375-24 mount thread.
