The CNC Warrior M18x1 RH to 5/8×24 RH thread adapter lets you attach 5/8×24 RH muzzle devices to an M18x1 RH threaded barrel. It works with 7.62/.30 caliber rounds and smaller. CNC Warrior optimizes its production and inspection process for the best possible fit and concentricity between both threads and the through hole. The adapter is made in the USA.

Key Specifications

• The barrel-side thread is M18x1 RH, so the adapter screws onto barrels cut to that metric pattern.
• The device-side thread is 5/8×24 RH, the common pattern many muzzle devices use.
• It works with 7.62/.30 caliber rounds and smaller, which sets the largest bullet it will pass.
• It has two large flats for tight installation against the shoulder.
• The full front shoulder is preserved, which squares and secures the muzzle device.
