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.

Perfectly rated springs. Great performance upgrade without overstressing internals plus you don't need arms like Schwarzenegger to prime! Thanks again.

Was a bit sceptical of the roughly double the strength of the standard spring until i installed them. Just from the sound of the darts hitting the wall you can tell they are much more powerful. Great product and turned up really quickly, will definitely be buying more in the future
