KNS Precision Thread Adaptor Features The KNS Precision Inc Thread Adaptor is machined to step a 1/2x28 threaded barrel up to a 5/8x24 external thread the standard pitch used by many .30 caliber suppressors and muzzle devices. This lets a .223 or 5.56 rifle mount hardware designed for larger bore firearms without needing a new barrel. Its nitride finish is applied for corrosion resistance and a tough long wearing surface that holds up to repeated mounting and removal. Installation requires only a 5/8 inch wrench so the swap takes just minutes at the bench. KNS Precision has built its reputation in the firearms accessory market on practical well engineered parts like this adaptor. The finished Black nitride coating matches the look of most factory barrels and muzzle devices keeping the installation visually clean. Because the adaptor is a simple mechanical thread conversion it adds no meaningful length or weight to the barrel assembly. Shooters building a multi caliber suppressor setup will find this adaptor a straightforward way to extend their existing can to more platforms.
