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 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 pounds, 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 estate for mounted optics and accessories.

This carbine is most effective for operators requiring a versatile, compact duty rifle suitable for entry teams, vehicle-mounted operations, and specialized tactical units where full-length AR platforms prove unwieldy. Professional shooters, law enforcement special response teams, and end-users seeking a modern 5.56 NATO platform will find the OB1L8913.7XL's balanced ergonomics and proven operating system support both iron sight and modern optic mounting solutions via MIL-STD-1913 rail interfaces. Installation of suppressors, aftermarket triggers, and modular furniture is fully compatible with standard AR-pattern components, allowing customization to match mission requirements without requiring specialized tools or gunsmithing.
