Sig Sauer Mcx 300 Aac Blackout 9 inch 30+1 Fde Ir Cerakote Short Barrel Rifle

The SIG SAUER MCX SBR 300BLK 9" FDE is a compact, semi-auto short-barrel rifle from the MCX series engineered for close-quarters maneuverability and suppressed shooting, with a 9-inch barrel and FDE IR Cerakote finish that holds up in field use and tactical applications. This serialized NFA firearm requires transfer through an FFL/Class 3 process, and its .300 AAC Blackout chambering allows you to run both supersonic and subsonic loads for reliable barrier penetration or quiet suppressed work; the MCX platform's gas system and modular upper make caliber and configuration changes straightforward for operators who need adaptability on patrol, in the blind, or on the range. The folding telescoping stock speeds movement in tight spaces and vehicles while maintaining adjustable length of pull for different shooters, and the semi-auto action with 30+1 capacity supports sustained follow-up shots without sacrificing control. Built from corrosion-resistant materials and featuring SIG's ergonomic controls, this MCX SBR blends modern sporting rifle ergonomics with duty-grade performance, making it a solid choice for tactical professionals, NFA collectors, and handgun-replacement carbine shooters seeking a compact, suppressor-friendly 300BLK platform.
