Call of Duty: Modern Warfare – 15 Secret Gun Variants You Can Craft | Gunsmith Guide

Call of Duty: Modern Warfare's new Gunsmith tool lets you truly customize your weapons - and some guns can be turned into totally different ones altogether. Everyone has their favorites from the series, and thanks to the many efforts of the community, there are some awesome alternate weapons you can craft using the Gunsmith station.

Once separated into several different weapons, the humble MP5 can be transformed into the stealthy MP5K or MP5SD. The M4AI can transform into a regular M16 and the AK-47 can become a lead MPK. There are plenty of other variants that don't just change how these weapons work, but change the model enough to match favorite weapons from Modern Warfare's long history. Let's dive in and see what we can create together.

15 Secret Gun Variations You Can Create | Gunsmith Guide

Below you will find descriptions on how to modify each gunsmith weapon. We will have the name of the weapon and then a list of mods to swap out to complete the weapon transformation.
