Carbine Gas System Configuration

The 10.5-inch barrel pairs with a carbine-length gas system, providing increased gas port dwell time compared to pistol-length systems at this barrel length. The micro low-profile gas block measures 0.750 inches in diameter and sits beneath the KeyMod handguard. The carbine gas system length offers compatibility with standard carbine-length gas tubes.

SB Tactical SBA5 Brace System

The SB Tactical SBA5 pistol stabilizing brace mounts to the included mil-spec heavy-duty 6-position buffer tube and provides adjustable length of pull through the 6-position adjustment mechanism. The brace features polymer construction and split-aperture design. The buffer tube accepts standard AR-15 carbine buffer and spring systems.

The package contains upper assembly, BCG, charging handle, buffer system components including tube, buffer, spring, castle nut, and end plate, complete lower parts kit with trigger assembly and small parts, and SBA5 brace.
