This Shepard Arms Custom BRN-180 is a modern take on a classic piston-driven design, optimized for the .300 Blackout platform. Finished in our in-house Carbon Gray Cerakote, this rifle blends a sleek, tactical aesthetic with the high-performance reliability of a short-stroke piston system.
This is a complete, suppressed SBR package designed for maximum signature reduction and superior ergonomics.
The Shepard Arms Performance Suite
BRN-180 Piston-Driven Upper (.300BLK) The BRN-180 system eliminates the need for a traditional buffer tube, allowing for a truly compact, foldable footprint. The piston system runs cleaner and cooler than traditional DI rifles, especially when shooting suppressed.
Custom Carbon Gray Cerakote Applied in-house at our Menomonee Falls shop, this premium ceramic coating provides superior corrosion resistance and a unique, professional finish that stands out from standard anodized black.
Sig Sauer 30cal Endure Suppressor w/ Dual-Lok We’ve upgraded this Sig Sauer suppressor with the Griffin Armament
Dual-Lok system.
The Dual-Lok Advantage: Made in Wisconsin, this is the most robust mounting interface available. It features zero wear items and a rock-solid taper lock that won't back off during high-heat strings of fire. No clicking, no ratcheting—just a precision fit every time.
High-End Component Selection
CMC Single-Stage Flat Trigger: Provides a lightning-fast break with a tactile reset, significantly improving accuracy and split times.
Inforce WML G2 (400 Lumens): An ergonomic, lightweight weapon light that offers intuitive activation and high-intensity output for positive target ID.
Red Dot Optic: High-contrast aiming solution for rapid target acquisition in any lighting condition.
