Compact Pistol Configuration

The 7.5-inch barrel paired with the pistol-gas system creates a responsive, easy-to-handle platform without sacrificing reliability. This configuration is purpose-built for close-quarters scenarios where compact dimensions matter. The barrel twist rate of 1:7 stabilizes standard 5.56 NATO ammunition effectively across typical engagement distances.

SBA5 Brace Stability

The SB Tactical SBA5 brace delivers a locked, stable shooting platform that improves control and accuracy compared to standard pistol grips alone. The nylon reinforced polymer construction provides durability while keeping overall weight manageable. The brace positions naturally against your arm for consistent shot placement during rapid fire sequences.

M-LOK Accessory Ecosystem

The free-float handguard uses M-LOK mounting slots, allowing you to attach lights, lasers, vertical grips, and other tactical accessories without interference. The aircraft-grade aluminum construction maintains rigidity while the free-float design isolates the barrel from handguard contact, supporting accuracy. This modular approach lets you customize the platform to your specific needs.
