The Sinus Brake was developed as a hybrid of muzzle brake and tuner to combine the best features from both worlds. The specially designed and replaceable threaded adapter makes installing the brake a breeze. The built-in compensator system, as well as the precise alignment bubble make the Sinus Brake an absolute must-have for every Long Range and PRS shooter.
By simply twisting the tuner, the harmonics of the barrel are influenced in such a way that an optimized exit angle of the bullet is achieved. This is reflected in a tighter group size.
Both factory and self-loaded ammunition can be "tuned" precisely and easily.
Available in all common thread sizes. Designed and manufactured on the highest quality level to give you the edge when it counts.
Note on the adapter shape:
Conical adapter for barrels up to 23,4mm (0,92") . Cylindrical adapter for barrels larger than 23,4mm (0,92"). Conical Victrix adapter for barrels up to 23.8mm. Cylindrical Victrix adapter for barrels larger than 23.8mm = Pro models and similar.
