SOLGW Scalper 5.56 NATO 13.9" Rifle

The Sons of Liberty Gun Works Scalper 5.56 NATO 13.9" rifle represents a purpose-built platform for operators who demand compact firepower without sacrificing reliability or ergonomics. Designed for close-quarters operations, dynamic entries, and vehicle-mounted deployment, this short-barreled rifle bridges the gap between pistol-caliber carbines and full-length AR platforms. The 13.9-inch barrel length delivers the ballistic efficiency needed for intermediate ranges while maintaining the maneuverability critical in confined spaces where barrel length directly impacts target acquisition and weapon handling.

Built on proven AR-pattern architecture, the Scalper integrates 5.56 NATO chambering—the NATO standard intermediate cartridge—with Sons of Liberty's precision engineering and quality control. The compact 13.9-inch barrel preserves the velocity window necessary for 5.56 ammunition to perform reliably on intermediate threats while the lightweight construction—approximately one pound as shipped—allows extended operations without fatigue. The rifle's modular design supports standard AR-15 accessory compatibility, enabling rapid reconfiguration for mission-specific loadouts including optics, lights, and rail-mounted systems without tools or gunsmithing.

Law enforcement tactical teams and military personnel operating in confined environments will find the Scalper's short profile ideal for vehicle operations, room clearing, and rapid deployment scenarios. The 5.56 NATO cartridge ensures commonality with institutional ammunition supplies and enables use of standard magazines found throughout professional armories. Professional operators should verify local regulations regarding short-barreled rifle registration and transport, as the 13.9-inch configuration may trigger NFA requirements in certain jurisdictions. Compatibility with standard AR-15 components—triggers, bolt carrier groups, rail systems, and stocks—ensures this platform integrates seamlessly into existing tactical ecosystems.
