Compact 9MM Platform Design

The 7.5-inch barrel length keeps overall dimensions tight while the 1:10 twist rate stabilizes 9MM projectiles effectively. The HBAR profile manages heat and maintains accuracy during sustained fire. This configuration is optimized for the 9x19 cartridge and delivers the velocity and reliability you need in a shorter package.

Vertex Billet Upper and Nitride Carrier

The Vertex Enhanced upper receiver is precision-machined from 6061-T6 aluminum and hard coat anodized for durability. Paired with the 416 stainless steel nitride bolt carrier group, this combination handles 9MM pressures reliably. The nitride finish on the carrier resists corrosion and wear during cycling.

M-Lok Accessory Mounting

The aircraft-grade aluminum M-Lok handguard gives you clean, intuitive mounting points for lights, lasers, or grips without adding bulk. The modular design keeps the platform lightweight while maintaining rigidity.

SB Tactical SBA4 Brace

The SBA4 adjustable brace offers multiple positions for different shooting styles and hand sizes. The design allows for consistent cheek placement and provides stability during firing.

Lower receiver not included. Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws.
