What HPA Nerf is Like In Play

As a nerf hobbyist myself, I’m always looking to improve my own setup on the field.. and of course, have more fun. 

You might have heard about nerf HPA (high-pressure air). It’s a fairly newer thing in the hobby especially in the US. 

If you want better accuracy, adjustable power on a single blaster (150-400FPS), try new designs, a satisfyingly cool shooting sound, or just a new experience on the field, then HPA might be your next thing. 

I had no idea what I was doing at first...

I started building my first HPA (high-pressure air) blaster in the shop.

I had heard that HPA could be the “next new thing” in nerf, but also heard that HPA was dangerous, commonly not allowed at events, and had a lot of new terminology and parts to learn and understand.  

I was also skeptical that HPA could actually out-perform other blasters. 

I also found HPA to be a lot safer than I originally thought. I made about every mistake you could with nerf HPA, but nothing blew up.

My first HPA blaster (the HPA U Talon Claw) came together. The HPA setup wasn’t as complicated as I imagined after I figured out what I was doing.

And the noise? Most satisfying thing in the world. 

And then I ran my HPA blasters in play…

I brought my Axiom to a small nerf war last week. 

Some of my buddies worried that the HPA firing noise might worry some neighbors, but the blaster wasn’t even as loud as my car’s engine. Fired a few shots to show them and we all agreed that it was quieter than we thought it would be. 

We were playing under 200FPS, so I grabbed my allen key and tuned my blaster down to make the coronagraph happy. The blaster was lightweight enough that I didn’t feel as tired after an afternoon chasing kids around.

Found out HPA can be super fun (and safe too!)

  • Any FPS you want (huge range between 150FPS to 400FPS)
  • Lightweight (say goodbye to a sore priming arm)
  • Easy setup (don’t get intimidated by all the jargon. It’s fairly simple in play.) 
  • Satisfying firing noise
  • Semi-auto ease of firing
  • Freedom to move around without a large blaster frame
  • Great consistency (with the right barrel and darts)

*While I will help you with the setup, it’s not totally foolproof. You still will need to know some principles about HPA to use it safely*

Why other nerfers get HPA...

Since then, I’ve done quite a few HPA builds for nerfers in the community. I asked a few why they bought their HPA setup. There responses were as follows: 

  • “A blaster to replace all blasters”
  • “To try the next new thing in nerf”
  • “To not be dead-tired after a day of play”
  • “Something with adjustable FPS”
  • “A blaster that’s more accurate than anything they have”
  • “To dominate the field in nerf”


Each blaster will be a little different, but the principles are the same. In fact, once you get your basic HPA setup (SuperCORE, regulator, etc), you can swap it in and out of basically any HPA blaster. 

Here’s an overview of how the Axiom works: 

The Axiom is a remote line HPA setup, meaning that you carry the HPA tank in a pouch or somewhere other than mounted on your blaster. 

I’ll post more information about other setups soon. A remote line setup isn’t a bad idea to start with if you’re just getting into HPA.
