Ergonomics and handling

The aluminum lower keeps mass down without sacrificing rigidity. The Glock-compatible flared mag well speeds combat reloads and reduces fumbling under stress — especially useful for duty and competitive drills. The free-float M-LOK handguard accepts lights and pressure switches without transferring torque to the barrel, preserving consistent point-of-impact and improving accessory flexibility.

Recoil and 9mm advantages

Configured in 9mm, the LAR-BT-9 offers low recoil impulse, faster follow-up shots, and widely available magazines and ammunition. The 4.5 inch barrel balances velocity and compactness, offering terminal performance suitable for defensive applications while remaining practical for everyday carry platforms or carbine-style setups.
