The SIG MCX Rattler LT is a compact 7.62 NATO short-barrel rifle built for operators and shooters who need power in a tight package. This SBR variant chambers the full-power NATO rifle round in a remarkably maneuverable 7.75" barrel, making it ideal for vehicle-mounted, close-quarters, and specialized tactical roles where a full-size rifle isn't practical but you need genuine rifle-caliber capability. The MCX Rattler LT's proven pedigree—rooted in SIG's modular MCX platform—gives you the handling and control of a submachine gun with the velocity and ballistics of a proper rifle.
Built in black, the MCX Rattler LT ships with a 30-round capacity magazine and is purpose-built for shooters who understand the trade-offs of short barrels: reduced velocity and range compared to longer guns, but dramatically improved handling and deployment speed. This is a serious fighting rifle for a specific mission set, not a general-purpose hunting or sport-shooting platform. If you're outfitting a truck, running specialized training, or building a dedicated close-range rifle system, the Rattler LT deserves a hard look.
As an SBR (short-barrel rifle), this firearm requires federal registration and compliance with National Firearms Act regulations. Ensure you understand all applicable federal, state, and local laws before purchase. The MCX Rattler LT is not a title I or sporting rifle—it's a regulated Class III item and should only be considered by shooters legally authorized to own NFA weapons in their jurisdiction.

The SBR configuration is regulated under the National Firearms Act.
Is the MCX Rattler LT legal to own?
As a short-barrel rifle, the MCX Rattler LT is a Class III / NFA weapon requiring federal registration, a $200 tax stamp, and ATF approval before legal possession. State and local laws vary significantly. You must verify your jurisdiction's SBR regulations and complete all required registration before purchasing. We recommend consulting a licensed firearms dealer or attorney in your state to confirm legality.
What comes in the box?
The MCX Rattler LT ships with one 30-round magazine. Ancillary components, sights, and optics are not included unless specifically noted at the time of purchase.
What is 7.62 NATO, and what is it used for?
7.62 NATO (.308 Winchester) is a full-power rifle cartridge used by military and law enforcement worldwide. It delivers significantly more velocity, range, and energy than intermediate cartridges, making it suitable for medium to long-range shooting, hunting medium to large game, and specialized tactical applications where stopping power and distance capability are priorities.
