Sig Sauer MCX Rattler 300 Blackout AR Pistol with Brace - 6.75" - 1x 30rd Mag

The SIG Sauer MCX-Rattler LT brings the original Rattler's compact firepower to a fully modular platform, giving special-operations-inspired shooters an ultra-short AR pistol with interchangeable barrels and handguards. Built with an adjustable gas piston system for suppressed or unsuppressed use, this AR pistol delivers fully ambidextrous controls in an even more capable package than the original Rattler.

Features:

• Cold hammer-forged barrel, chambered in .300 AAC Blackout
• 6.75" or 7.75" barrel for an ultra-compact build
• Adjustable gas piston for suppressed or unsuppressed use
• Fully compatible with all MCX LT barrels and handguards
• Fully ambidextrous controls, including bolt catch and release
• SIG flat blade match trigger
• SIG SLX/SLH suppressor-ready flash hider
• Includes one magazine

Full compatibility with all MCX LT barrels and handguards means the Rattler LT can be reconfigured into different barrel lengths and calibers using the same core platform, rather than being locked into a single fixed setup. The adjustable gas piston lets shooters tune the action for suppressed or unsuppressed fire, and fully ambidextrous controls, including the bolt catch and release, make the pistol equally easy to run for left- or right-handed shooters. .300 Blackout is purpose-built for suppressed and subsonic performance, making it a natural fit for this compact, piston-driven platform.

SIG Sauer is trusted worldwide for firearm performance and durability, and the MCX-Rattler LT reflects the same modular design philosophy developed for special operations use across the broader MCX platform.
