SOLGW Gun Works OB1L8913.7XL 13.7" Carbine

The Sons of Liberty Gun Works OB1L8913.7XL 13.7" Carbine is a purpose-built rifle engineered for professional operators, law enforcement, and serious civilian shooters who demand precision and reliability in close-to-medium engagement scenarios. This compact carbine bridges the gap between full-length rifles and submachine gun handling characteristics, making it ideal for vehicle operations, building clearance, and dynamic tactical environments where maneuverability without sacrificing ballistic performance is paramount.

The 13.7" barrel length positions this platform in the intermediate-length rifle category—short enough for confined spaces, yet long enough to optimize velocity and accuracy with modern 5.56 NATO cartridges. Sons of Liberty Gun Works manufactures this carbine with the same precision and quality control standards applied to professional-grade military platforms. The OB1L8913.7XL designation denotes a short-stroke piston-driven operating system optimized for short-barrel configurations, delivering reliable cycling across suppressed and unsuppressed applications while managing heat and fouling typical of compact rifle designs.

At 13.9 lbs, this rifle maintains a balanced profile—heavy enough to manage recoil impulse and sustain rapid fire, yet light enough for extended handheld operations. The overall length of 45 inches (measured with stock fully extended) keeps the weapon compact for transport and close-quarters work while maintaining a functional sight radius and rail. This carbine is ideal for those who require a reliable and versatile firearm for various tactical applications.
