Sinus Precision Benchrest Barrel Tuner, developed for .22lr and Benchrest/F-Class.
The perfect addition to the PRS/Long Range KK or F-Class rifle to achieve maximum precision. Optimal use for competitions where no muzzle brake is permitted or when no optimization of the ammunition is possible, e.g. with the .22lr/ lfB. FEM optimized extremely heavy tuner barrel weight and high total weight to calm barrel vibrations. Depending on the adapter, the entire tuner weighs 365 grams, which shifts the center of gravity further forward, especially with the lighter 22lr rifles for the PRS disciplines, and results in a better balance.
Other features include the extremely wear-resistant DLC+ coating, which is very easy to clean, the easily readable engraved vernier and the outstanding quality. An extra lockable hole for the flicker band screw is also included. The Sinus Benchrest Barrel Tuner uses the same thread adapters and hook wrenches as the Sinus Brake. The tuner weights are also compatible with each other. Made to give you the decisive advantage when it counts.
We recommend for the tuner test with .22lr, 10 shots for every half turn. 8 full turns are available. Can be used up to .338 caliber.
