Sig Sauer MCX mod brings Modern Warfare II rifle to GTA V

The Sig Sauer MCX from Evandrotorquato is the kind of modern-carbine replacement GTA V’s weapon scene keeps circling back to for a reason. It ports the M13B from Call of Duty: Modern Warfare II and frames it as a real-world Sig Sauer MCX-based rifle, which gives it the right blend of current military styling and believable hardware for players who care as much about the silhouette as the stats.

What makes this release stand out is that it is animated and built with high-quality textures, so it does more than swap the model sitting in the inventory wheel. In motion, that matters. The rifle reads as a contemporary modular carbine without drifting into sci-fi excess, which is exactly why it fits so well in police loadouts, private-security setups, and high-end criminal kits, especially in roleplay and cinematic scenes where a weapon has to look like it belongs in the frame.

The MCX also lands in the middle of a broader modern-weapon trend that has been running through GTA V modding lately. It sits comfortably alongside other recent tactical rifle swaps, including the AUG A3 release, but the MCX has a cleaner, more mainstream profile. It looks like the sort of rifle a serious operator would actually carry, not a museum piece or a fantasy gun dressed up for effect.

Installation stays familiar for veteran modders. The instructions use OpenIV and an Easy Mod Folder approach, with placement in the weapons archive locations that regular GTA V armorers already know. That lowers the friction for anyone keeping a dedicated single-player folder for weapon replacements, and it helps explain why this sort of port keeps finding an audience even in a crowded mod market.

The credits tie the project into the same conversion ecosystem that has been feeding GTA V’s firearms library for years, with Scobalula, Greyhound, Cordyceps, and Activision assets all listed. The early downloads and likes point to immediate interest, and that tracks: a polished MCX is exactly the sort of rifle that can make a tactical pack feel current without looking imported in a distracting way.
