PRODUCT DETAILS
TECH SPECS:
Purpose-built for professional duty, the SIG SAUER MCX SBR in .300 Blackout offers unmatched reliability and compact firepower—now in a rugged Flat Dark Earth (FDE) finish for enhanced concealment and durability in any environment. Designed for law enforcement, military, and first responders, this short-barreled powerhouse features a 6.75" cold hammer-forged barrel, ideal for suppressed use and tight quarters.
Its short-stroke gas piston system ensures smooth cycling and reduced recoil, while ambidextrous controls and a low-profile M-LOK handguard provide maximum adaptability in high-stress scenarios.
The folding and collapsible skeleton stock enables rapid deployment and transport without compromising precision or ergonomics. The FDE finish adds a tactical edge and operational camouflage for desert and urban settings.

Ask a QuestionProven Arms & Outfitters A bolt-action rifle requires the shooter to manually operate a bolt to load a round, eject the spent casing, and chamber the next round. In contrast, a semi-automatic rifle is designed to automatically eject the spent casing and chamber a new round with each pull of the trigger. Semi-automatic rifles offer faster follow-up shots, while bolt-action rifles are typically more accurate due to their design.
