Details
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.

Shipping & FFL
Firearms are shipped only to a Federal Firearms Licensee. We must have a signed copy of the receiving dealer's license on file before shipment. Once the firearm arrives, you complete ATF Form 4473 and a NICS background check with that dealer. Transfer fees are set by, and paid to, the receiving dealer.
All firearm sales are final. Inspect the firearm at your dealer before completing the transfer — once it has transferred to you on a Form 4473 it cannot be returned to us. Defects are handled under the manufacturer's warranty.
