Is your sniper rifles’ performance just not cutting it anymore? Looking for increased power and accuracy without having to switch rifles entirely? Well look no further thanks to the BOLT HPA Conversion Kit from Wolverine. This kit replaces the spring power source originally built into your compatible sniper, and instead utilizes either HPA tanks or a single 12g Co2 cartridge as the power source. Not only are you getting the BOLT system, this kit also includes the required Tokyo Marui Cylinder head for your VSR-10 airsoft rifle. Most airsoft enthusiasts stray away from the Wolverine BOLT gas upgrade due to its complicated installation process, Airsoft Station recommends professional installation for this kit. Using a drill to create access holes in your rifle may be necessary for the trigger assembly and HPA hose. The kit can be wired anywhere on the rifle the player wishes, but is most commonly wired to the rear stock or pistol grip where there is enough room to house the Co2, cables, and small battery. Pairing the BOLT system with the Wraith Co2 system (not included) results in weight reduction and increased maneuverability for maximum rifle control in all scenarios. If players choose to use HPA tanks, they must be carried separately and connected to the rifle through the included external hose. Running off of Co2 keeps the rifle compact and eliminates the risk of getting the gas hose caught on trees or other debris.

Due to the design of the Wolverine BOLT kit, the trigger will fire every time it is pulled but will only fire a BB when the bolt has been cocked back and in the fire position. Although the Wolverine BOLT system has no moving parts and does not use a FCU trigger, a 7.4v battery is still required to charge up the Electro Pneumatic system that powers the revolutionary 3 way valve design while also providing increased trigger response. A specially designed bolt was included in this kit to minimize the bolt pull allowing for faster and more consistent follow up shots. Being able to fluctuate the input PSI between 80-180 lets players determine the FPS for various play styles, and is able to achieve over 600 FPS when using 0.20g BBs. The proprietary Quick-Change end cap lets players quickly swap power cartridges in record time. Patent pending “Air Saver” technology successfully decreases air consumption by 50% without affecting the performance, meaning you can play longer on a single tank fill up. Although this kit comes with the required Tokyo Marui VSR-10 Cylinder Head, the universal design of this kit allows for many sniper rifle models to be upgraded including Echo1 PSR-10, JG BAR-10, Echo1 M28, and Cybergun FN Herstal SPR. Become the most dominant on any battlefield with the BOLT HPA Conversion Kit from Wolverine.
