Sig MCX Rattler LT w/PCB 5.56NATO 7.75" Barrel 30+1

The Sig Sauer MCX Rattler LT PCB, chambered in 5.56 NATO, is a cutting-edge PDW-style pistol designed for compact storage, rapid deployment, and maximum reliability. Featuring a 7.75" barrel, this pistol is engineered with Sig’s adjustable short-stroke gas piston system, optimized for consistent performance both suppressed and unsuppressed.

The lower receiver incorporates ambidextrous AR-style controls, offering intuitive handling and compatibility with a wide array of AR-pattern accessories.

Additional features include a full-length Picatinny rail for mounting optics, multiple QD sling attachment points, and a 30-round polymer magazine. Lightweight, compact, and highly configurable, the MCX Rattler LT PCB is an ideal choice for home defense, professional duty, or personal protection in confined environments. For those seeking a premium PDW pistol with the versatility and quality Sig Sauer is known for, the MCX Rattler LT PCB stands out as a top-tier option.
