Click Here for Fitment GuideThe Sierra-5 delivers the perfect balance of overall sound and flash reduction while maintaining a compact profile with minimal weight. Designed for hard, professional use, the Sierra-5 suppressor is rated for full-auto, and utilizes an ultra-durable, fully welded construction. The outer tube is made from premium stainless steel, and features knurling to provide a strong purchase for securing/removing the suppressor or for use with heat-protective wraps. The interior of the Sierra-5 utilizes all Stellite baffles with full penetration laser welding to ensure a solid, robust monolithic core structure, which is then welded to the outer tube for additional strength and durability. In addition to greatly mitigating sound and flash signature, this configuration also provides a low blowback, short-pressure impulse. Other features of the Sierra-5 include a HUB socket, allowing the suppressor to be configured to the user’s specific needs, and a small hole drilled through the blast chamber makes it possible to pin and weld your adapter or insert to the suppressor. Furthermore, the Sierra-5 ships with either a Xeno mount or a KeyMo mount.
