KNS Precision Thread Adapter 1/2x28 to 5/8x24 – Convert Muzzle Threads for Suppressors & Muzzle Devices

The KNS Precision Thread Adapter converts barrels with 1/2x28 threads to accept muzzle devices threaded 5/8x24. This allows shooters to mount suppressors, brakes, or flash hiders designed for larger caliber rifles onto smaller caliber platforms—common when running 5.56/.223 hosts with .30 caliber accessories. Precision-machined for concentric fit, this adapter maintains proper alignment critical for accuracy and safe suppressor use.

Installation is straightforward: thread the adapter onto the existing 1/2x28 barrel threads, torque to manufacturer specifications, and attach your 5/8x24 device. Made from heat-treated steel with a durable black oxide finish. Verify your barrel has sufficient shoulder length and that overall length with adapter meets legal requirements. Always check concentricity before firing with a suppressor attached to prevent baffle strikes.
