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

Great Interactive Option
Color: Blue
To start, I have been very happy with this purchase. A couple of key points for me are durability and being able to keep my dog's attention. I have had it for almost a year, just a month shy, and she hasn't managed to get through the foam outer shell even though she tries real hard to do so. Let's just say, she's hard to find toys for because of her habit of finding the point of failure where she can pick and gnaw at until the toy is no longer safe for her to have. With this toy, she not only found her match, but it also has her watching, waiting, and even stalking. Only one small issue has recently occurred: the motor has started having an issue where the charge doesn't hold, and it doesn't remain on afterwards. I have reached out to Cheerble directly to see about replacing it since I am still within their 12-month timeframe, and they responded right away.

Quality product for the right dog...
Color: Orange
Honestly it's a really cool product well constructed and moves around on its own with several different modes. The design id brilliant with a tough rubber ball that unscrew to expose the element that makes it move in the middle. The dog won't be able to unscrew it but you can if you ever need to replace the ball for any reason but it would take some work for a dog to destroy the outer ball. Almost like "Kong" type material. The ball is about the size of a softball and the element inside is about the size of a golf ball. I thought my dog would love this but she was afraid of it, which is strange because she's afraid of nothing. Anyways I gave it to my neighbor upstairs and she has a yorkshire terrier who plays with it all the time so it all worked out great. Quality product . Good job!

Thought it was a good idea but not for my dog
Color: Blue
Seemed great but my dog continued to bark at it. Finally she hid it and I haven’t looked for it.

Durability
Color: Blue, Color: Blue
won’t give this product 1 star because my dog still had a good time with it for a few hours. After opening and preparing it, I gave it to my dog and it definitely caught his interest. However, when he chewed on it, plastic pieces started breaking off and he began swallowing them. This product is definitely not suitable for aggressive chewers.

Winner !!!
Color: Orange
This amazed us. For perspective, we're talking about a three year old white german shepherd who if he's in the mood, has and can kill a toy within minutes or oddly enough be gentle with furry balls and carry them around as if they are his babies. He's an odd duck. Anyway, since he was a pup, and to this day, he'll play and entertain himself, he'll grab a ball, throw it up in the air, then pounce on it as if it's from outer space. It's really quite cute and funny. Because of those two things I was looking for something interactive that would entertain him and confuse him....let's be honest, watching a confused dog is one of life's great pleasures. I tried two other interactive balls and they were crushed immediately. After reading a lot of reviews, people with german shepherds said this ball actually had a life span. I thought the third time could be the charm and ordered one. Well, I think it actually may be from outer space because he's obsessed with it and hasn't taken a bite out of it. He hasn't once chewed it or even teared little pieces off. The three settings are great. Sometimes he likes one better than another, then forgets about the others. I'll change it up to one he hasn't seen in a while and the whole game starts over again. He'll throw it up in the air as he does with his others, watch it and try to figure out which way it's going to go. And yes, he will pounce on it if he times it right. The size is perfect, it's heavier than your average ball but, that's what make it sturdy. I have to sneak it away when he isn't paying attention to charge it, otherwise he'll sit, stare and cry if he knows it's on the counter charging. It's a lot of fun for all of us. I'm so happy I bought it...... I say give this ball a chance even if you have a beast with killer instincts. I'm buying another for a friends 2 year old golden retriever granddog. Thank you Cheerble.
