Harmonic Barrel Tuner Eagle Vision Universal - Black

Making an air rifle more accurate doesn't always have to go through ammunition. The Eagle Vision Universal – Black Harmonic barrel tuner offers an alternative route: by influencing the oscillating movement of the barrel during firing, you tune the barrel vibrations to the ammunition you're using. The result is better grouping without having to fiddle with the velocity of your pellets or slugs.

Setting up the barrel tuner works through a systematic test-and-adjust process. After installation, you shoot a test group, adjust the tuner, and shoot again. You repeat this for all available positions. Thanks to the clear markings on the Eagle Vision Universal – Black Harmonic barrel tuner, the best position can be easily found afterwards. Keep in mind that the optimal setting may differ per pellet or slug — if you switch calibers, it's wise to run through the test process again.

Compatibility is broad: the tuner fits on virtually any air rifle with external ½ UNF threads. The package includes four end caps with ½ UNF, M14X1.25, M20X1 and M18X1 threads respectively, supplemented with eight caliber adapters for .177, .22, .25 and .30 calibers. The first set of adapters is without threads; the second set has ½ UNF threads, so you can also mount a silencer on it. A versatile choice for sport shooters who want to get the maximum out of their air rifle.
