Free “Gun Disassembly 2” App A Fun Learning Tool

As a gunsmith I sometimes find myself squinting at poorly scanned schematics of rare guns. Stumped halfway through a project, I scratch my head trying to figure out how the doohickey is held in place by the whatsit and what the doohickey’s function actually is in there. That’s probably why I think the free Gun Disassembly 2 app from Noble Empire is so cool. Available for iPhone, Android, Macs and PCs, the program is a wealth of knowledge about what is inside your favorite gun and how it actually works.

I downloaded the PC version and had it up and running in a minute or two. There were a couple of patches that needed auto-updating, and one of them failed; it was only newer sound effects and the program runs fine regardless. The main screen gives us 3d computer representations of dozens of fireams and a couple of other oddities such as the RPG-7 and a Russian field artillery piece. Ten of the most popular guns can be viewed for free, but you’ve gotta pay for access to the others. Judging by the free samples, the developers have put a ton of work into accurately representing the internal parts and their fitment. You can disassemble, assemble, view demonstrations, and “fire” each gun in slow motion to see how the parts move as the firearm operates, all in 3d and from any angle. Zoom out to see everything or zoom in to see how just a few parts interact with each other.

Here is the lockwork on a Smith & Wesson Model 53. You can cock, decock, fire and reload the gun virtually and see how everything moves. An “X-Ray Vision” mode just shows the parts I want highlighted at the moment while outlining everything else in a ghostly green.



A “game” mode has you racing against the clock to click on parts in the correct order to disassemble and reassemble the gun in the fastest time possible. While it won’t compete with World of Tanks for my gaming time, it is a handy way to truly learn the design of the firearm. Toggling labels on helps your brain make the transition from “Doohickey” to “Spring Torsion Pin”. The 3d models are incredibly complex and truly faithful to the actual firearms. Here is a fully disassembled Sig “Commando” with labels turned on.


Gun Disassembly 2 is more than a fun free program to mess around with. It can unlock in our minds a better understanding of the engineering behind some very interesting firearms. I recommend trying it on your Mac or PC because the complexity of the firearms is best viewed on the largest screen available, but if you are stuck somewhere with just your phone, this program will be a great time-eater for gun enthusiasts like us. And if you can’t get your Ruger Mk II back together for some reason (hey, we’ve all been there), Gun Disassembly 2 is way better than squinting at that old 2d schematic!


We asked the makers of  Gun Disassembly 2 if they were willing to give us promo codes for our readers to unlock  some of the paid guns. They have given us four lifetime account promo codes which unlock every gun currently featured in the app and all future additions, 10 promo codes that unlock the Minigun, AK 47, M16, Steyr AUG,  Browning M1919 A4, M1 Garand, Thompson, Desert Eagle .44, Remington 870 and Barrett M107, and 15 promo codes to unlock the Colt SAA, Maxim, RPG -7, HK G36e and FAMAS F1. The first 29 readers to ask for a promo codes in the comments will be emailed a code. The codes only work on the Windows PC and Android version of the app (blame Apple). UPDATE: Codes all gone. Took just 20 minutes before they all went. We will email the lucky readers with their codes within the next 24 – 48 hours.

    Please add me!

  • I have been using the app everyday since before Christmas. It is an amazing app for any gun nut. I love pulling apart guns and this app lets me pull apart guns I would never get my hands on in real life. I have learn’t a lot already, like how the M32 MGL grenade launcher rotates its cylinder (a gas operated piston that unlocks a ratchet)

    According to the developer, new (paid) guns that will soon appear in the app are the Ruger 22 Charger, MAC 10, Winchester 1873, DP 27, Lewis gun, M14, Welrod and SKS.

    Cool, needs more guns

  • Adam

    I can see this leading to at least a couple dozen self taught designers appearing before manufacturers with brilliant designs, but no credentials. or perhaps just alot of wasted time. 🙂 As a side note, it’d be great if something similar existed for things like watches or engines

    • noob

      a proof of concept model in ABS plastic printed on a rep-rap should turn a few heads.

    • Para

      Well, dude, they’ve got out versions for the human body, cars, motorcycles (available via Gun Disassembly itself) and are working on versions for tanks and helicopters (for which the first two models will apparently be the BMP-3 and Mi-24 respectively).

  • noob

    that sig commando looks like it’s died and gone to heaven 🙂

  • Marcos

    Please e-mail me a code!


  • Jon

    Hey another fellow tanker. Got to do a shout out to World of Tanks its such a good game.

  • Please, write to the support if you have any questions.
    We answer e-mails every 24 hours.

  • mosinman

    Gotta love world of tanks!

  • Would it be too much to ask that the authors of these posts be identified? It is obvious that not all postings are done by the same person but the writers are rarely identified. Chris Cheng is occasionally but he is about the only one.

    • noob

      I second this. I’d be interested to see your byline and short bio. Helps put a name to the article, and you can get fans!

    • Phil White


      We are all ID’d on each article. When you open the articles own page each author is in the top left corner. They always have been.

      If the article is on the first page you open on the blog the authors name is also posted at the bottom under the article–that’s always been true as well.

      Phil W

      • Thanks,

        Well Duh on me. Guess I didn’t read the fine print. I never noticed the names in the upper left hand column since they are somewhat disassociated with the post. It was unclear to me what that was.

  • Brian

    A free code would be great!

  • Jake

    I’d like a code

  • tincankilla

    for those of you with other guns, Gun Disassembly HD (on the iPad) has a few other guns, including the CZ-75, which is why I got it.

  • NYC_Ducati

    May i have a lifetime code? This game is really helpful!

  • Rob

    i wish you could get some more codes 🙁 having to pay for the M1 Garnad is a complete rip off :\

  • Mike Knox

    Sure is fun but it’s nothing compared to the real thing..

    • Para

      It’s so unbelievably awesome when you live in the Socialist Commonwealth of Great Brit-ain.

      I couldn’t get a firearm if I started the process now for at least two years. And I’d certainly be completely unable to find a semi-automatic non-rimfire to see how those functioned.

      It’s a valuable substitute for a budding designer.

      Besides, opening up a rifle would only show you what the parts were.
      It wouldn’t show you what they did.

  • AznMike

    Man I need to check this site earlier next time, didn’t know there was going to be codes. Hope we can get more free codes in the future. Anybody reminded of the gunsmith in Ghost Recon: Future Soldier?

  • Codes have all been mailed out. Maybe we will get some more free codes in the future.

    • Seth z

      Did i get a code?

  • Moxy

    I’d really love to see a Linux version of this! My pc’s are all running Linux except for my work boxes and I’m not sure how HR would react to having this installed on my windows pc’s at work lol.

  • swc64844

    Where can I get a version of this at?

    • David Murphy

      They have a facebook app and you can also find it in the apple store and google play. Its really fun

  • SycHEVanov
  • Turner

    It was great , except i ran mine on the pc…

    Don’t suppose you have any codes for the pc version?

    Some of the high score times seems almost impossible for me. Or maybe its easier on the iphone..I don’t know.

    I so far only have minor dislikes… the ‘game’ is too automatic rather than manual. I mean, I clicked on a weapon part and it puts the part in right where it belongs automatically. I know this is design this way so that its ‘user friendly’ but I prefer the challenge personally
    And some of the parts orders are too scripted even though it is possible to put other parts in first.

  • Lolinski

    where do we type the codes in, and can we register the code to a account so that we can access it on other computers( I have multiple computers in my house which I use if the others are busy because family uses them)

  • Gadyis

    I need code, give me a code,

  • compability issue….video card ds not started………..

  • Jarrid Horner

    Can I please get the code. I have spent $30 on this and a bunch of new guns just came out and I can’t afford to spend any more.

  • lucas cortez

    Please e-mail me a code!


  • valentin Stephan

    can I have a code please ? thank you.

  • Rick G

    This App or “game” this sounds like an awesome data base to have access to however I’m haven’t downloaded it myself do to security concerns! Why should this application need access to my phones PROTECTED FILES and Is set to locate ALL ACCOUNTS?? To me it seems that I would be letting the wolf into the Hen house!!!
