Heavy Barrel Design for Precision

The Sagger HBAR barrel provides the stability needed for consistent accuracy at distance. Heavy barrels reduce harmonic vibration and heat distribution, which improves shot-to-shot consistency. The 16-inch length balances velocity retention with maneuverability in a carbine platform. Enhanced phosphate finish protects against corrosion during extended shooting sessions.

Free-Float Handguard and Modular Mounting

The M-LOK handguard isolates the barrel from contact with the upper receiver, eliminating a major source of accuracy inconsistency. The 15-inch length provides ample rail space for mounting optics, lights, and accessories. Integrated QD mounts and anti-rotation tabs ensure secure attachment. Oblong lightweight cutouts reduce weight without compromising structural integrity.

7.62x39mm Bolt Carrier Group and Gas System

The complete bolt carrier group is purpose-built for 7.62x39mm dimensions and operates with the carbine-length gas system. The .750-inch micro low-profile gas block delivers reliable cycling while maintaining a clean upper profile. Nitride finish on the BCG resists wear and corrosion through extended use.

Compatibility and Configuration

This is a complete upper assembly only. The bolt carrier group and charging handle are included. A lower receiver, lower parts kit, buffer tube, buffer, recoil spring, castle nut, and end plate are not included. Verify magazine compatibility with your lower receiver before purchasing, as 7.62x39mm feeding can vary based on magazine design and feed ramp geometry.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. BCG and charging handle are included with this complete upper.
