PRS170 MKII Suppressor

Mack Brothers PRS170 MKII Suppressor

Next-Gen Performance

The PRS170 MKII is the next evolution of our proven .30 caliber suppressor—purpose-built for precision rifle shooters who demand uncompromising performance. Featuring our signature thread-over-brake (TOB) quick-detach system, the MKII offers fast, secure attachment and repeatable bore alignment via a robust 40-degree angled shoulder. The updated design also includes a HUB 1-3/8×24 breech end, making it compatible with a wide range of mounting systems.

Now fully welded and weighing just 8.7 ounces, the MKII delivers a 2.5 oz weight reduction from the original PRS170—while maintaining maximum sound suppression. Crafted entirely from certified 6AL-4V and 3AL-2.5V titanium, it combines exceptional strength with ultra-light construction. A removable muzzle cap and included takedown tool make cleaning simple and efficient.

Engineered for consistency. Built to last. Proudly made in the USA.
