The Primary Weapons Systems 5/8x24 thread mount is a suppressor adapter designed to work with barrels threaded to the 5/8x24 standard. If you're running a suppressor setup on an AR platform or bolt-action rifle and your barrel is cut to 5/8x24, this mount provides the interface you need to thread your can on securely. It's a straightforward, no-nonsense piece that handles the job without fanfare—exactly what you want from muzzle device hardware.
PWS built its reputation starting in 2008 by testing gear across different rifle platforms and ammunition volumes. That hands-on approach is reflected in their muzzle device lineup: components designed for real-world use, not lab benches. The 5/8x24 thread mount is finished in black anodized aluminum, a durable coating that resists corrosion and handles the abuse of field use.
Whether you're building a suppressed hunting rifle, setting up a precision .308 for the range, or configuring a 5.56 AR, having the right thread pitch on your barrel matters. This mount does one job: give you a reliable connection point between your barrel and suppressor. No adapters, no converters—direct mounting with proper fit.

This mount is designed for barrels threaded to 5/8x24 specification. Confirm your barrel's thread pitch before purchasing—this is not an adapter and will not fit other common thread sizes like 1/2x28 or .578x28.
Yes. The 5/8x24 thread mount provides the interface between your barrel and a suppressor threaded to accept 5/8x24 connection.
This is a direct thread mount. It threads onto your 5/8x24 barrel and your suppressor threads onto it—no additional adapters needed if your components match the specification.
