Power Up Kit for VSR-10/MB03/MB07 Series Airsoft Sniper Rifle
Fitted to a JG Bar-10 (TM VSR10 clone). The spring has slightly smaller diameter then normal springs so fits the piston snugly, but means piston wont work on normal diameter springs. Also had to 'nibble' about 1.5cm off the end of the spring to bring it back down below the Safe Limit for most sites (500FPS) and the average limit (450FPS) for bolt actions.
