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

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).
<p>Can you make a four drum mod</p>
<p>OK... you've made a 18 shot maverick and a 18 shot strongarm... do you think you can make instructions on how to make a 18 shot cycloneshock???</p>
<p>why cant i open the .stl</p>
Would it be possible to do this using three 3d printed 9 shot cylinders? Just curious. Thanks!
<p>Yes, But it is not reccommended because 3d prints are not nearly as clean, durable and precise.</p>
Thank you!<br>
<p>is there a .stl for the barrel?</p>
From where you we can buy these parts<br>
<p>I won a strongarm as a door prize and was frustrated at the constant reloading. Thanks for making this instructable!</p>
<p>You can remove the air restrictor as long as you do it through the hole in the front (NOT EASY!!). This leaves the buffer at the back which the plunger strikes.</p>
<p>actually I saw a post of a guy who chrono'd his darts before and after removing the &quot;air restrictors&quot; which are actually just dry fire prevention mechanisms, and he found a large decrease in dart velocity and accuracy, and stated that the only way to get more power is a stronger spring.</p>
<p>This is fantastic. Great job</p>
<p>Great instructable and I love the paint job! Very District 9.</p>
<p>Great Job Brittliv!!!</p>
<p>very nice!!! Thanks for posting a picture!</p>
<p>how long do you think it would take for this mod to work. ( Not including paint and primer and sanding.)</p>
<p>That depends on how clean you work, but you should bei able to finish it in a weekend </p>
<p>i need to make this gun in about a month. Should I just 3d print it or just carve it from wood. Thx</p>
<p>Hello! Can you send the pictures of the mold each piece ?</p>
How do you make the thing that can connects the three drums
How did you get that effect with the paint? Sponge?
Im not sure if these screws work please tell me where you bought your screws if they dont
<p>Hi, do you have a stl file for the barrel?</p>
<p>yeah i really need it too!</p>
<p>What kind of paint did you use? What was your procedure? </p>
I love it!!!! Very creative. I was able to improvise off of your instructions and I was able to make mine work properly w/ a 3% failure rate
<p>This is absolutely amazing. I love the triple barrel mod and I love the paintjob even more! Amazing. I don't know if you've seen it yet, but Nerf is coming out with a new blaster in the Zombie Strike series called the FlipFury. The Nerf Zombie Strike FlipFury has two barrel chambers that can be &quot;flipped&quot; over and rotated into place. Nerf had to have seen these double and triple barrel mods and effectively incorporated the modders work into their official line of products. I did a quick write up on the Nerf FlipFury on my website (link in profile)</p>
<p>Hey I was wondering if i could buy the drum connecter peice thing. Just send me the Ebay, amazon or whatever you use's link. Thanks in advance</p>
<p>Hi, I am really sorry, but since I live in Germany, the postage would be very high. </p>
<p>I live in europe (netherlands) i was wondering if i would be able to buy the 3d parts if not then ill just stick to single chambers :D</p>
<p>Can I buy that 3D parts? Beacouse I haven't got 3D printer.</p>
Looks like a Maliwan pistol from borderlands
<p>wow!!! one thing how long did it take</p>
<p>wow!!! one thing how long did it take</p>
<p>Fantastic tutorial. I'm actually going to rebuild it and on the photo with the 3D Printer Parts I can see 5 printed parts, but there are 4 STLs. Is there a STL missing, or do I have to print out a pice twice? Thanks.</p>
<p>Damn, I totally forgot... Madnesz has asked me for it, too. I can't find <br> it anywhere and have to redesign it. I will do so this weekend. What <br>type of printer do you have? I could give you the .x3g file.</p>
<p>Unfortunately not a MakerBot. The Printer asks for .stl files. But I can give it a try to convert the .x3g to .stl </p><p>Thanks a lot.</p>
<p>I've uploaded it. I hope it fits. Else please get back to me. </p>
<p>Great, thank you! ^_^</p>
<p>Congratulations Britt, your creation is amazing! I love the look, it's perfectly Borderlands-esque :D</p><p>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... :(</p><p>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!</p><p>Thanks and congrats again! :)</p><p>https://www.instructables.com/id/Nerf-Strongarm-Borderlands-2-Hyperion-gun-replica/</p>
<p>Eyyyyy Darthorso my friend! </p><p>I'm not sure if they ship to Italy, but they'll definitely print a single object for you....<br>Looks like they've been to a few makerspaces there.<br><a href="http://www.shapeways.com/">http://www.shapeways.com/</a></p>
<p>Eyyy craft! :D How are you my friend? ^_^</p><p>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</p><p>But you are a true friend for giving me that web link! :) Thank you again, stay great! :D</p>
<p>Very well, sir, very well indeed.</p><p>Glad to help! I'm always doing my best to connect people to resources... :)</p><p>Cheers!</p>
<p>Yep! And you are doing a great job! ;)</p><p>Stay great, crafty! ^_^</p>
Excellent work! Would you mind also uploading the stl file for the second ScrewHolderBack?
<p>Oh, you are right, I forgot. Sadly I can't find the file anywhere. Please give me a few days. I will redesign it. </p>
Hey BrittLiv I really like your work I wonder if you could post an instructable with the nerf Jolt IX-1?
