The Holeshot Muzzle Tuner is built for serious rimfire competitors who demand absolute precision. This tuner slips onto the muzzle approximately 1″ and secures firmly with three nylon-tipped screws within a knurled locking area, ensuring a repeatable and stable hold every time.
Crafted from lightweight anodized aluminum with easy-to-read black numbering, the Holeshot is fully adjustable from 0–500 in 0.001″ increments, allowing shooters to fine-tune barrel harmonics for superior group consistency and accuracy. Whether you’re shooting NRL22, PRS Rimfire, or precision benchrest, this tuner delivers the edge you need.
The end is threaded 1.375-32, making it compatible with popular accessories such as the PQP Tuner Weight Kit and PQP Precision Tube, giving you flexibility to customize your setup.
