18 Shot Nerf Strongarm

Picture of 18 Shot Nerf Strongarm
After building my 18 shot Nerf Maverick I have been asked countless times, whether it is possible to build an 18 shot Nerf Strongarm. So I decided to give it a shot (no pun intended :-)).
In comparison a few more alterations are needed and the pieces that connect the barrels are a bit more challenging, but other than that it wasn't overly complicated to build. I still urge you only to attempt this mod, should you be convinced that you are able to execute it. Otherwise you might damage your blaster.
Even if you are not planning on building an 18 shot version of the blaster and are just generally interested in modifying a Strongarm, I think this instructable is worth a read (especially the first step).

Take a look at the video:

Btw. I am completely aware of the irony of taking a blue-orange-white blaster apart in order to sand and prime it and afterwards painting it blue-orange-white again... but as some of you already noticed in the comments, I wanted it to look like something straight out of Borderlands.

Step 1: Common misconceptions + how to increase the speed

Picture of Common misconceptions + how to increase the speed
I have read multiple times that people suggested to remove the what they call "air-restrictor" from the plunger and to fill the small hole that is on the top (as shown in the third picture).


Even though they might tell you that this improves the strength of you blaster, it doesn't! In fact, this actually damages your blaster, because it is not an air-restrictor, but an ingenious method to prevent dry firing. Since after building this 18 shot blaster I had some plungers left over I tried to do the mod and to compare the results by measuring the dart speed with a chronometer.
I also removed the barrel posts from one barrel, to measure the effect. Unless you are planning on using Stefans (If you don't know what I am talking about, here is an instructable) I wouldn't suggest you to do so either, because it also decreases the strength of the elite darts.

The only effective way to improve the dart speed that I found was to change the spring! The second picture shows the improvement after adding the Orange Mod Works (OMW) kit (from here).

Congratulations Britt, your creation is amazing! I love the look, it's perfectly Borderlands-esque :D

The triple barrel gives an original and unique look to the guns, I hope I can have acess to a 3D printer... they're very rare here in Italy, even for customer-service. You can find 3D printers only in large industries that won't make you a single piece... :(

I've made an instructables (my 1st one) about Nerf Strongarm, it's an aesthetic mod. Take a look and tell me what you think about it!

Thanks and congrats again! :)

Eyyyyy Darthorso my friend!

I'm not sure if they ship to Italy, but they'll definitely print a single object for you....
Looks like they've been to a few makerspaces there.

Eyyy craft! :D How are you my friend? ^_^

Thank you a lot for your suggestione! But in these days I've found a friend of mine who own a little 3d printer and can do something for me! :D :D :D

But you are a true friend for giving me that web link! :) Thank you again, stay great! :D

Very well, sir, very well indeed.

Glad to help! I'm always doing my best to connect people to resources... :)


Yep! And you are doing a great job! ;)

Stay great, crafty! ^_^

Excellent work! Would you mind also uploading the stl file for the second ScrewHolderBack?
BrittLiv (author)  Madnesz23 days ago

Oh, you are right, I forgot. Sadly I can't find the file anywhere. Please give me a few days. I will redesign it.

Hey BrittLiv I really like your work I wonder if you could post an instructable with the nerf Jolt IX-1?
Deadpunk4 months ago

I bet if you sold the the 3D printed pieces and included a link to these instructions it would sell well. I for one would defiantly by them from you.

qubist Deadpunk1 month ago

You can go to the /r/3Dprintmything subreddit ( and someone will be able to print for you!

BrittLiv (author)  Deadpunk4 months ago

I will think about it.

I'm in love with that paint job. The first thing that came to mind was the alien weapons from District 9.

What company do you think this would be? I'd say Jakobs because it's a revolver, but I could see Hyperion as well.
gunnyboy4 months ago
Wow! And I thought your maverick looked good, but this, this is incredible. And that paint scheme... Amazing.
knexbug4 months ago

TOTALLY AWESOME, can you do this with the hammer shot?

BrittLiv (author)  knexbug4 months ago

The Hammershot doesn't have the same mechanism to turn the barrel in order to load it like the Maverick or Strongarm. So this mod would be more complicated.

knexbug BrittLiv4 months ago
Ah yes, I suppose that would be because of the hammer cocking mechanism

Most people would be pleased if they got 44000 views in 3 years but in two weeks?

BrittLiv (author)  knexbug4 months ago

I am surprised, too

Have you ever considered doing this with Nerf Mavericks?

BrittLiv (author)  ttang54 months ago

Be honest, how much of the instructable have you read?

Quester554 months ago

Great Idea, Perhaps one day you should bring your ideas to the Nerf Manufactures & Get a Good Job, in their Planing Dept.

Fantastic mod, and awesome paint job! I have access to a 3D printer at work, so I tried to download your files, but it seems like the only one that works is the first one... I don't know if it's just me, but the download links for the other two aren't working... I love your mod, and it is going to make for a fantastic hvz secondary! It would just be nice if I could download the links to get started haha :) (basically when I click on the links, it brings me to a weird page with a bunch of text on it...It looks like text from the 3D print model or something...) Thanks!

BrittLiv (author)  Krazaam4 months ago

Try to right click on it and than click "Safe Link As...". It should work.

Krazaam BrittLiv4 months ago
It worked! Thanks!
