Product Overview
The SIG Sauer MCX Rattler LT is a compact .300 Blackout semi-automatic pistol built around the modular MCX platform. Its 6.75-inch cold hammer forged barrel uses a 1:5-inch twist rate and is fitted with a SIG QD suppressor-ready flash hider. The adjustable gas piston supports reliable operation with suppressed or unsuppressed ammunition. Fully ambidextrous controls, including the bolt catch, bolt release, and safety selector, provide consistent handling from either side. An aluminum frame, flat-blade trigger, and optic-ready upper receiver complete a versatile configuration for compact sporting and defensive applications.
