SBA5 Pistol Stabilizing Brace Configuration

The SBA5 brace is included and ready to attach to the buffer tube. This nylon reinforced polymer brace provides a stable shooting platform while maintaining the pistol frame classification. The brace is designed for shooters who want ergonomic control and consistent cheek weld on a compact AR platform. Configuration remains dependent on your intended use and local compliance requirements.

Freefloat M-Lok Handguard System

The 6061-T6 aluminum handguard floats freely from the barrel, eliminating contact that can shift zero under different shooting conditions. M-Lok slots run the length of the rail, allowing you to attach lights, vertical grips, or other accessories without removing the handguard. The black anodized finish resists corrosion and provides a professional appearance while maintaining a lightweight profile.

Carbine-Length Gas System Performance

The carbine gas tube length pairs with the 10.5-inch barrel to deliver reliable cycling in a compact package. The 0.75-inch gas block shelf is sized for standard carbine blocks. This configuration balances speed and control for rapid follow-up shots while managing recoil impulse effectively in the shorter barrel profile.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included. The SBA5 brace configuration is intended for shooters selecting their own setup based on legal requirements in their jurisdiction.
