The S-Series SL7i BoreLock is a premium sound suppressor designed for hunting and precision rifles in calibers ranging from 7.62 to .338 Lapua Mag. It is specifically designed for bolt-action firearms.

This suppressor provides impressive sound suppression of 31–33 dB (.308 Win, measured 1 meter from the side of the barrel) and effectively reduces both recoil and muzzle flash, enhancing shooting comfort and making shots considerably quieter for both the environment and the shooter.
