While we originally manufactured our Tuners for the Rimfire Benchrest fraternity, they are proving to be just as successful in Centerfire Benchrest as well.

Our Tuners have a Micrometer style adjustment and are adjustable in 0.01mm increments throughout their entire range.

The smallest Barrel either tuner will fit is 18.6mm (0.732″).

Both Tuners are bored to 22 mm internally. That means any barrels smaller than about 22.5 mm will not end up with a stop. While they are intended for use on heavy barrels, they will still clamp onto barrels down to 18.6 mm.

The only difference between the Standard and Lite tuners is weight. We added it to our range because there is a demand for tuners fitted for the lighter categories. They both work exactly the same. Because the Lite tuner has a weight advantage we added an extra 40mm extension.

Both Tuners are manufactured in 6262 Aluminum.
