If we're talking about a unique online airsoft shopping experience, then we should be talking about Airsoft Megastore. Why do I say so? It's because they are the only airsoft retailer (and also wholesaler) that lets customers build their own custom guns in an interactive way online. You can build your own custom AR or AK airsoft rifle in either AEG or Gas Blowback configurations that suit your taste.

Airsoft Megastore is heavily focused on making the Custom Gun Builder a showcase feature at their online store, believing that customers prefer to have a hand in the customization of their airsoft rifles. With the Custom Gun Builder, the customers and Airsoft Megastore can easily understand each other on how the customization shall proceed and within the specifications that can be met by Airsoft Megastore as parts are already based on existing inventory.

Now, they proudly present the SR-25 Gun Builder for those looking into a custom DMR to bring to the next milsim event. While at first glance it looks like another M4, it still has a different configuration to have its own section in the Custom Gun Builder. It has an elongated Version 2 Gearbox since it has a bigger upper and lower receivers designed to take in a 7.62mm magazines for DMRs.

I am actually surprised that there is a selection of rails for the SR-25 and there are KeyMod rail systems available for it. You can still go for the traditional front end and upper if you still prefer the old look of the SR-25. Just like the other weapons platforms that are available in the Custom Gun Builder, right after making your selection of parts to put the rifle together, you then get to select the accessories and consumables that will go with it. While you are making all the selections the Custom Gun Builder automatically calculates the total so you can keep track if you’re going over your budget or not.

Using the AMS Custom Gun Builder is very much straightforward and a lot of thought of making it an easy-to-use online airsoft shopping tool was put into it. The list of airsoft guns that can be customized with it is getting longer and Airsoft Megastore are open to suggestions on what airsoft gun you think they should prioritize to add to the Custom Gun Builder in the future.

It would be interesting if they build a mobile app version of the Custom Gun Builder for those who are on the go. I have tested it on a mobile phone (iPhone 6) and it works good as long as the screen is big enough but would be chose using it on a smaller screen. A native app is probably a good answer for using the Custom Gun Builder on a mobile device.
