The Sons of Liberty Gun Works (SOLGW) MK1 AR-15 pistol is engineered around a purpose-built platform focused on durability, refined ergonomics, and hard-use performance. This configuration pairs a black anodized finish with an 11.5-inch P3 stainless steel barrel and a billet receiver set. Developed and tested to meet demanding operational requirements, the MK1 incorporates an integrated approach to rail design, control placement, and cable routing. The SOLGW MK1 10.75-inch rail provides extensive accessory space, integrated cable routing, built-in texturing, and a continuous Picatinny top rail. Its MK1 DriveLock rail attachment system uses Broadsword tabs and recesses, supported by dual stainless steel anti-rotation dowels. Low-snag control fencing, an enlarged magazine well, and an optimized bolt catch area contribute to the platform's carefully considered layout. The lower receiver features a Liberty 2-stage trigger with a 4.5-pound total pull, an ambidextrous Badger safety selector, and a nine-position SOLGW A5 receiver extension paired with an A5H2 buffer. The package includes one 30-round Gen3 PMAG or a compliant magazine, depending on configuration. SOLGW backs the MK1 with a lifetime warranty and Critical Use Replacement coverage.
