STEALTH ADDITIVE WORKS TISHA 5.56/6MM SUPPRESSOR
The Stealth Additive Works Tisha is a K-size 5.56/6mm suppressor built from 3D-printed Grade 5 (ELI) titanium. At 4.1 inches long and 10.5 oz without mount, it is one of the shortest and lightest rifle suppressors in its caliber range. With the included Plan B mount system, it adds only 3.8 inches to your barrel length.
The Tisha uses a patent-pending internal geometry designed to reduce back pressure while maintaining strong muzzle and shooter's ear suppression. PEW Science tested the Tisha on a 10.3-inch MK18 with Federal XM193 and recorded a composite Suppression Rating of 49.6, ranking it as the highest-performing 5.56 suppressor in their Rankings at the time of testing (SSS-6-209, December 2025). That level of suppression from a K-size can is worth paying attention to.
The exterior profile draws from Soviet-era aesthetics, modeled after the Delta Tek flash hider. "Tisha" is a nod to the Russian word for "quiet." The variable-diameter body measures approximately 2.1 inches at the proximal end and 1.8 inches at the distal end, per PEW Science measurements.
The Tisha is rated for all 6mm projectiles and below, including 5.56/.223, 6mm ARC, 6mm Creedmoor, and 6mm GT. It works on bolt-action and semi-auto platforms. For high rate of fire or full-auto use with the titanium version, the included 2-port muzzle brake (or a similar multi-port brake) is required.
The suppressor uses standard 1.375x24 HUB threading and ships with a Plan B-compatible hub and a 2-port muzzle brake with 1/2-28 threads. It is ready to mount out of the box.
