Wolverine BOLT HPA Engine

PRODUCT DESCRIPTION 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. It requires no FCU and is also compatible with our new WRAITH: CO2 Stock system. Compatibility: Tokyo Marui VSR 10* (CYLINDER IS REQUIRED) Echo1 PSR 10* (CYLINDER IS REQUIRED) JG Bar 10 (CYLINDER IS NOT REQUIRED, BUT RECOMMENDED) Echo1 M28 (CYLINDER NOT COMPATIBLE, USE STOCK CYLINDER)
