Suppressor Compatibility
Our threading interfaces are purpose-built to hold Class 3A thread tolerances, ensuring safety and precision match fits for your high-end suppressors.
Direct Thread Caps: We highly recommend you add a thread protector to any threaded muzzle. Choose either a basic knurled version, which is pictured below or a smooth blended protector that is made of the same high quality stainless steel as the barrel core, but machined to a seamless finish.
Suppressed Fire Warning: Always verify suppressor alignment with a professional bore-alignment rod before firing the first round on a new installation.

1/2" - 28 TPI
Standard for .30 caliber and undersized bores (e.g., 6.5mm, 7mm, .308). Requires minimum muzzle diameter of 0.740".
5/8" - 24 TPI
Its slightly larger diameter compared to smaller thread options provides added strength and alignment security for muzzle devices, while still maintaining a relatively compact and low-profile interface.
