TRIARC Systems x TACHUNTFISH - La Bruja TSR-15 SPR 5.56mm 16" Rifle

The TRIARC La Bruja SPR is a purpose-built rifle that blends elite craftsmanship with tactical innovation. Engineered for precision shooting and sound suppression, this rifle is a true “tack driver,” delivering sub-MOA performance and rugged reliability in a sleek, mission-ready platform.

At its core is the new 16″ TRACK 2.0 SPR profile barrel, chambered in 5.56mm with a 1:7 twist and 1/2x28 muzzle thread, optimized for pairing with the OCM5 suppressor. The hand-fitted forged upper and lower receiver set ensures tight tolerances and consistent accuracy, while the TRIARC NP3 bolt carrier group with enhanced 5-coil extractor guarantees smooth cycling and long-term durability.

Outfitted with a 13″ Rev 6 TRILOK handguard, Superlative Arms adjustable gas block, and Radian Raptor LT charging handle, La Bruja SPR is built for adaptability and control. The B5 Systems collapsible precision stock, Magpul MOE-K2® grip, and TRIARC enhanced mil-spec trigger round out a rifle that’s as comfortable as it is capable.

Finished in Ano Black Cerakote®, this rifle is ready for suppressed shooting, long-range engagements, and everything in between.
