The Wolverine BOLT is an HPA conversion kit for Bolt Action sniper rifles. It helps you to STAY HIDDEN, STAY ON TARGET, and SAVE AIR. Because it is intrinsically quiet, you can be the ultimate stealthy sniper. Because there is no spring, you can seamlessly cycle the action while staying locked on your target. With our new Air Saver technology, you get the most out of your HPA tank or CO2 cartridge. Since it is electro-mechanical, it requires no FCU!

Technical Highlights 

  • Electro pneumatic: This means there will be a small battery, but NO FCU. The trigger simply attaches to the outside of the trigger box and is actuated by the trigger. When actuated it powers the valve and fires the BB. This means the consistent output of a solenoid without the complexity and battery drain of an FCU.
  • Exclusive 3-way valve design created by Wolverine Airsoft and manufactured by MAC powers the system.
  • NO MOVING PARTS: During the firing of the bb nothing in the system moves other than the Solenoid Valve opening.
  • Patent Pending Air Saver™ Technology: Allows you to simultaneously save up to 50% of your air per shot and match the volume air output of the system to the barrel.
  • Optional 1 Piece aluminum bolt simplifies the installation especially on guns where the cylinder head is pinned to the cylinder.
  • Will have the option of using a special version of our WRAITH for self-contained co2 cartridge use with no external air line. ~150 shots per cartridge is possible even at 2+Joules!
  • Input pressure(subject to change): 80-180psi.
  • Output Energy: 1-3+J depending on setup and BBs used.
