What's New in Version 1.15

*If you are having issues with the app not loading after updating from an older version, please UNINSTALL the app, then REDOWNLOAD it. This should fix any loading issues. Sorry for the inconvenience.


The latest update to the GUNSTRUCTION player features new part categories, functionality, vendors and of course parts!

In Explode Mode you will notice we added the much asked for new Magazine Pulls as a point of customization. Simply select a compatible magazine and chose the Magazine Pulll that fits!

The new patch will include the entire line of Duracoat paint and camo options! Now you can chose from over 300 custom colors and camos!

We have also added Brownells to the list of dealer links, and encourage everyone to shop around and utilize these links within the program.

Version 1.15 will also feature direct connection to ARFCOM’s Gear Locker. This is an extensive database of parts information, reviews, high res pictures, and places to buy. The Gear Locker also allows you to print out or e-mail your build to yourself or others, and see your saved builds outside of GUNSTRUCTION. To access the Gear Locker simple click on the ARFCOM logo found in each part’s “Part Info” screen. From the web player you can also load up the Gear Locker via the tab on the left hand side of the window.

Behind the scenes we have made some performance upgrades, fixed some bugs, and corrected some information for parts. We have also unified saves across all platforms. Now you can share builds made on your mobile version of GUNSTRUCTION with web users and vice versa! The URL you generate is universal.

New Vendors:
Aero Precision
Mag Pod

Awesome App

This app is actually a lot better than I was expecting. It has a wide selection of AR's and tons of aftermarket components from lots of different manufacturers (don't worry- plenty of Magpul). I also love the fact that it has the Sig brace as an option.

I have a couple minor complaints, though:
1) The interface used to add accessories (like rail sections) could be more intuitive, but it's not hard to get the hang of it.
2) The default view angle for changing colors is the left side (non-ejection side), but the color swatches only match the color on your model if you're looking at the right (dimly-lit) side at right angle.
3) It would also be nice if you had the option to flip MBUS sights down while playing... Just a thought.

Anyway, I'm having lots of fun with it and I'm glad somebody took the time to make it.

Build Your Dream Ar

This app uses real AR parts and even get to see the real prices of
The part and gives you the link to buy it. The next cool thing that this app does is it gives you a complete parts list in the end that you can print out to bring to your ffl to order the parts. Overall great app even though it could use just alil touch-ups on the drag and place accessories, other than that definitely worth the $2

Almost perfect

This is the most extensive gun builder I've used. Program runs smoothly and there are a ton of options. I have to ignore the price tags which make this app half useful. It doesn't have any parts for budget builds. I was surprised I didn't see Midwest industry and a default cheap upper or lower such as PSA.
This app is perfect for seeing how parts will match up as long as you ignore how much it all costs.
Also, if you search for this in your webrowser, it is free.
