JBU Performance Kits
These are some of the best kits for the money. If you are looking to achieve a 400+ fps, then these kits can help get you there.
Includes: M120 Spring, Reinforced Piston, Metal Spring Guide with Bearing, Aluminum Air Nozzle, 2 port Cylinder, Aluminum Cylinder Head and Piston Head.
NOTE: Many experienced players will also purchase and install a new reinfoced piston, metal shims and possibly some heavy-duty gears for maximum durability.
Some AEG's may require a stonger battery to power the 120 stainless spring. Please email our tech dept or call us at our store if you have any questions.
