Also fits the new Umarex Octane air rifle.
The Archer Airguns XMV Tune Kit for Ruger Air Hawk and Blackhawk Air Rifles provides a significant increase in muzzle velocity of 80fps - or even more - compared to an average “out of the box” gun in .177 caliber, an increase of over 20% in muzzle energy using the same pellets!
The XMV Tune Kit has been developed by an exhaustive analysis of the barrel/breech seal/compression tube interface of these air rifles; a major cause of muzzle velocity loss in standard factory guns. The kit allows you to minimize air loss and thus maximize muzzle velocity.
Archer Airguns XMV Tune Kits give the precision parts and expert information you need to custom tune your gun - gaining significant fps - within minutes and without the need for a chronograph or any special tools. They enable you to gain the maximum performance from your Ruger Air Hawk, Air Hawk Elite or Blackhawk air rifle at low cost.
XMV Tune Kits work with both .177 and .22 caliber air rifles.
It’s simple to do. Very importantly, no irreversible changes or modifications are required to your airgun. And you can have fun doing it!
This kit also fits the Ruger Air Hawk Elite, Ruger Air Hawk Magnum, RWS/Diana 34, Xisico XS25 series and XS28M air rifles.
The kit includes:
3 precision machined steel shims
3 high-quality, high durometer breech seals (2 are spares)
