The Sons of Liberty Gun Works MK1 Recce is a purpose-driven rifle built for those who demand uncompromising performance in a fighting platform. Chambered in 5.56 NATO and featuring a 14.5-inch pinned and welded barrel, this rifle is engineered for reliability, durability, and precision under real-world conditions. From its billet receiver set to its advanced rail system, every component reflects SOLGW's commitment to hard-use performance and refined execution. At the core of the MK1 Recce is a fully integrated billet upper, lower, and rail system designed for rigidity and minimal deflection. The MK1-specific rail features a continuous M1913 Picatinny top rail, integrated cable management, laser texturing, and seven-sided M-LOK compatibility-offering a stable and adaptable platform for modern accessories. The medium contour barrel utilizes 3-groove polygonal rifling and conservative gas port sizing, enhancing accuracy while maintaining reliable cycling. A titanium extended barrel nut with advanced coating improves heat management, ensuring consistent performance during sustained use. The A5 buffer system further refines recoil impulse, providing smoother operation and improved control during rapid fire. Premium components round out the package, including an NP3-coated bolt carrier group for enhanced lubricity and durability, a Liberty 2-stage trigger for a clean, predictable break, and ambidextrous controls for versatile operation. Paired with a B5 grip and Magpul DT-PR stock, the MK1 Recce is built for shooters who expect their rifle to perform without compromise.
