Barrel Tuner Eagle Vision with Muzzle Brake & Air Stripper 1/2 UNF - Black

With this Eagle Vision barrel tuner with muzzle brake & air stripper ½ UNF - Black you can finely tune the barrel of your rifle to the ammunition you’ll be using. You can use this tuner to correct for the oscillating motions in a barrel. By adjusting that frequency, you can significantly improve the accuracy of your air rifle. Before, you’d only be able to do so by experimenting with the velocity of your ammunition, but it can now be done by simply tuning your barrel with this all-in-one barrel tuner by Eagle Vision. Tuning your barrel is a process of trial and error. After mounting the barrel tuner onto the barrel, you’ll have to shoot a group. Adjust the tuner slightly and shoot another group. Repeat that process until you’ve cycled through all of the barrel tuner’s settings. The setting that allowed you to shoot the tightest group can easily be found again thanks to the clearly visible markings on the Eagle Vision barrel tuner with muzzle brake & air stripper ½ UNF - Black. The optimal setting can and will differ per pellet or slug, so it's very important to shoot new test groups whenever you switch calibres.

This all-in-one barrel tuner also acts as a muzzle brake and air stripper. There are a total of six long slots on the sides (three per side) of the Eagle Vision barrel tuner. It redirects the released air to the sides, which counteracts recoil. This makes it considerably easier to hold the rifle stable.

You will receive four calibre adapters along with the Eagle Vision barrel tuner with muzzle brake & air stripper ½ UNF – Black, which can be used to fit the barrel tuner onto a number of different calibres. These adapters can easily be interchanged and you can mount them firmly. You will receive the following calibre-adapters: 
• 4.5 mm (.177)
• 5.5 mm (.22)
• 6.35 mm (.25)
• 7.62 mm (.30)
There are eight holes on the front of the air stripper, which can be used to screw it in tightly. The barrel tuner by Eagle Vision can be mounted onto a barrel with ½ UNF thread.
