Sig Sauer Mcx Rattler 300 BLK 5.5 inch 30 Rounds No Brace

The Sig Sauer MCX Rattler Handgun in 300 BLK brings rapid deployment, thin agility and precision to a compact PDW platform, featuring a 5.5" barrel and a no-brace pistol configuration that keeps the package as discreet and maneuverable as possible while delivering the robust capabilities of the MCX family; the MCX series uses a short-stroke gas piston system for reliable semi-auto operation with suppressed and unsuppressed use, and the free-floating M-LOK handguard paired with a PDW upper provides a stable mounting platform for optics and accessories that tactical shooters, patrol officers, and serious range enthusiasts will value. With its 30-round capacity, diminished overall length and controllable recoil in 300 BLK, this handgun is ideal for close-quarters training, vehicle operations, and lightweight expedition carry where rapid follow-up shots and compact handling matter. Buyers should note transfer through an FFL is required. If you want a purpose-built compact rifle-style pistol from Sig Sauer that blends CQB functionality, modular MCX design, and proven reliability, the MCX Rattler 5.5" 300 BLK is engineered for that role.
