Nerf has a bewildering array of semi-automatic blasters, typified by the Stryfe. This wiring kit listing is for all of those, and comes in low power (for MTB Rhino and similar 130 motors) and high power (for MTB Hellcat and similar 180 motors) variations. If a specific blaster is not listed at a given power, then it's because we don't recommend (and thus do not sell) that power kit for that blaster.

Kit contains:
* Appropriate MOSFET (based on power level)
* 10K+ resistor
* Diode (because otherwise the FET explodes - sometimes literally)
* Through-hole PCB for easy assembly
* Wire lengths based on the blaster (wire size varies by power)
* Pre-wired male JST connector for easy interfacing of the switch to the PCB
* Right angled pins for easy interfacing of the JST connector to the PCB

If you require additional or spare parts, then please let us know using the "Custom Order" feature.

We also offer a "Do it yourself" version of the kit where we provide a metre of each colour of wire, plus the other components. This can be used for any blaster we don't have a specific kit for, but there won't be any fitting instructions - you're on your own!

We offer high and low power versions of this product because different motors have different needs and the cost difference is large enough for it to be economical. If you are unsure, we recommend the low power option with suitable 130 motors (eg: MTB Rhino) for ease of installation and because that makes it harder to reach muzzle velocities in excess of 130 feet per second (which is a limit that many UK clubs set as then the kinetic energy of a dart is not high enough to cause permanent eye injury). We always recommend eye protection, regardless.

Boring legal bits:
Item is not a toy, unsuitable for persons under the age of 14.
Listing is for the stated item(s) only, and any darts, blasters, magazines etc are for illustrative purposes only.

All blasters are modified at your own risk. Modified dart blasters are not toys and upgrades should not be purchased by those under the age of 16. Blastersmiths UK Ltd does not accept any liability for damage or reduction in lifespan of your blaster. Blastersmiths UK Ltd also does not accept liability for any injury caused during or after modifying your Nerf blaster. It is the end user's responsibility to use a modified blaster appropriately and safely - eye protection is strongly recommended when using any modified blaster. Purchase and use of one of these items is taken as acceptance of these terms.

These springs are great, I bought two, and they made a massive improvement to both my retaliator and rampage, they now fire hard enough to be competitive in any nerf war without being to difficult to prime. I can wholeheartedly recommend them to anyone wanting a performance upgrade that is easy to fit. You guys are the best, and I will definitely be a return customer. Many thanks from a very happy nerf hoarder.

This mega spring is awesome. I fitted it into my mega magnus and it has made a world of difference. Power and range are now on par with all my elite blasters. Prime is noticeably firmer but still manageable. Highly recommended for magnus although it looks short compared to the original spring it performs really well. Thanks again guys you are fantastic.
