Description
Purpose-built for modern bolt-action rifles while remaining fully capable on gas-operated platforms, the Stille 8.6 is a versatile suppressor engineered for hunters and precision shooters who demand maximum performance across large-caliber rifles. Designed from the ground up around bolt guns, it delivers exceptional signature reduction, balance, and consistency where it matters most-without limiting platform flexibility. Constructed from 3D-printed titanium, the Stille 8.6 prioritizes weight savings and durability, while an Inconel 718 blast insert and blast baffle dramatically increase service life by resisting erosion and high-pressure wear. Ships w/ B&T 5/8×24 Direct mount
Chambered in 223/338 Lapua Mag, it’s built to deliver consistent, reliable performance for that caliber. As a suppressor from B&T, it’s built to fit cleanly into a larger build or serve as a direct replacement part.
