Description
The HUXWRX RAD Direct Thread Adapter is built for shooters who run fixed-barrel pistols and want a clean, repeatable way to mount a suppressor without a quick-detach system. It threads directly onto a 1/2×28 muzzle and presents 1.125×28 threads on the suppressor end, which means it serves as a conversion point between your barrel’s standard pistol threading and the RAD suppressor’s mounting interface. That compatibility extends across the RAD 9 and RAD 45 models, so a single adapter can move between host firearms without buying platform-specific hardware.
The adapter is machined from 17-4 stainless steel, a grade chosen for its strength-to-weight ratio and resistance to the heat and pressure cycles that accumulate at the muzzle. The black nitride finish is applied after machining and works into the surface rather than sitting on top of it, which means it contributes to corrosion resistance without adding meaningful dimensional thickness that could affect thread fit. Machined wrench flats are included, so installation and removal are controlled and repeatable rather than relying on improvised contact points that could damage the finish or mar the threads.
This is a purpose-specific component rather than a universal adapter. It is designed around the fixed-barrel format, where the barrel does not tilt or rotate during the firing cycle, ensuring the suppressor stays in consistent axial alignment with the bore. If your setup matches those conditions and you are already running HUXWRX suppressors, this adapter is the straightforward, factory-intended way to connect them.
