*Clearance Sale - Price Slashed!*

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
  • Metal Trigger Catch
  • Polished Metal trigger
  • 5Kg Mainspring
  • Silicone grease
  • O-ring
  • Trigger and trigger catch springs
  • Plunger Head Plug (Optional: needed in certain Rampage versions)

*Modifying blaster may wear out or damage components. Please do so responsibly and at your own risk!

Excellent kit to learn July 25, 2017
Reviewer: Matt from Roanoke, VA United States  
I bought this kit as my second upgrade I have done to my nerf blasters. It was a fantastic kit to learn the inner workings of the rampage as it gave me a little trouble (let me clarify, not OMW fault). I had a few problems initially with the metal trigger as it had a tendency to catch and would not release the plunger, so I decided to stay with the plastic stock trigger to save frictional issues. The other minor problem I had was with the plunger rod's inner red housing. The housing kept being sucked out and would get lodged in the tube making the plunger get stuck, I removed that with no major issues to range or power. I did not want to glue it as I feared the glue may increase friction or glob it up. I oddly appreciate all these little intricacies as one of the reasons I bought this was to both upgrade and learn more about how my nerf blasters work.

Rampage Unleashed Solid January 7, 2016
Reviewer: Anonymous Person from WA United States  
I purchased this kit for my son's birthday and a nice father/son project in advance of a nerf party.  This was my first mod kit experience.  The quality and instructions are top notch.  A lot of engineering obviously went into the product.  Overall the blaster performance is up significantly resulting in longer range, power and accuracy.
