The Rampage Final Stage kit replaces the internal components that are most likely to fail under increased spring tension with high strength POM and zinc alloy. All of the corners and edges of the POM components have been radiused to increase strength and the plunger head has been redesigned for durability and to reduce the wear on the plunger body. The replacement spring is rated at 5+ kg and is designed to function as smoothly as the stock spring while more than doubling the dart’s velocity at the muzzle. The included plunger head plug is an optional part that should be used if you experience trouble priming your blaster. The plunger head plug makes up for a loss of draw length found in some versions of the Rampage shell.

Included in this kit:

• POM Plunger Rod
• Metal Reinforcement Plate

• Plunger Head Plug (Optional: needed in certain Rampage versions)
