From CRIMSON:

Any power you could need without sacrificing any consistency

In collaboration with Waldo Dynamics, I am very excited to showcase our new and unique to the market VFC NPAS!

What makes the Crimson NPAS standout from the others on the market?

Let's cut to the chase, what makes this NPAS different from the rest? Especially if you already have one....

Our design incorporates a tighter internal bore which allows for far more consistent FPS results at the 0.9 - 1.2 joule range, making it ideal for anyone operating within those limits. A graph has been made, by the great guys at FireSupport, at the end of our product photos to demonstrate this against the stock valve. This clearly shows just how consistent then Crimson NPAS truly is. A game changer for such a small cost.

Also, don't worry; Just because the bore of the NPAS itself is narrower doesn't mean you can't also achieve higher energy outputs (we have seen past 2 joules on standard barrel lengths with 0.36g BBs). We are also testing reports that it is making people's GBBRs more gas efficient (so far it seems to be true from our tests).

The Basics:

An NPAS allows you to tune your GBBR to your desired FPS/Joule output easily and seamlessly in the field using a simple 1.5mm hex key (found in most hex key tool sets). Once installed (which is demonstrated here on our own very clear video), simply remove your bolt from your GBBR, adjust through the front of the nozzle with a hex key (Clockwise for less energy output, counter-clockwise for more), reassemble and test your results.

This is perfect for players looking to be under limits no matter the time of year, BB weight, or with gas/pressure used. It really is a "must-have" component.

The material used is a stronger Nylon Polymer in the iconic Crimson red, making it extremely easy to identify on your tech bench as well as when it is installed. You will not lose track of who's VFC NPAS is who's (not that you will need any others after this!).

Installing an NPAS will require some teching knowledge and a small amount of tools. Be careful when adjusting your NPAS to ensure you don't totally unscrew the adjustment screw, this goes for any NPAS on the market.

Crimson, it's red
