Commemorating 250 Years of Marine Corps Excellence
In a tribute to the United States Marine Corps' quarter-millennium of service, Sons of Liberty Gun Works (SOLGW) has revealed an exclusive collection of MK1 rifles adorned with authentic Frog Skin camouflage patterns. This limited release honors the legendary Pacific Theater warriors who donned the distinctive pattern during World War II, with collectors able to choose between authentic Jungle and Beach colorways.

A Masterpiece of Modern Engineering Meets Historical Heritage
The foundation of this commemorative piece is SOLGW's premier MK1 platform, which showcases precision-machined billet construction throughout the receiver group and proprietary rail system. This isn't merely a cosmetic tribute – it's a fully-featured combat-ready rifle built to the exacting standards that have made SOLGW a trusted name among military professionals and serious shooters.
The heart of the system features an uninterrupted M1913 Picatinny rail spanning the entire top surface, complemented by intelligent cable management channels and aggressive laser-etched texturing for positive grip in adverse conditions. The innovative 7-sided M-LOK attachment points provide maximum versatility for accessories while maintaining the rail's structural integrity.
Performance-Driven Design Elements
Central to the rifle's performance is its precision-crafted barrel featuring advanced 3-groove polygonal rifling technology. Available in both 11.5-inch carbine and 14.5-inch mid-length configurations, these barrels deliver exceptional accuracy potential while maintaining reliability across a wide spectrum of ammunition types. The standard 5/8×24 threading accepts common muzzle devices, while the .750" gas journal ensures proper gas system function.
Thermal management receives special attention through the implementation of a titanium-constructed extended barrel nut, enhanced with specialized coatings to efficiently dissipate heat during sustained firing sessions. This attention to detail extends to the enhanced A5-length buffer system, which delivers noticeably smoother recoil impulse and improved weapon control during rapid fire.
Premium Components Throughout
No expense was spared in outfitting these commemorative rifles. The heart of the action features a bolt carrier group treated with durable NP3 coating for exceptional corrosion resistance and self-lubricating properties. The Liberty charging handle incorporates streamlined, low-profile latches that resist snagging while maintaining positive manipulation.
Shooters will appreciate the crisp, predictable break of the Liberty two-stage trigger system, while the ambidextrous Badger safety selector ensures equal accessibility for all users. Ergonomic considerations include the proven B5 pistol grip and choice of either the adjustable SBA5 stabilizing brace for pistol configurations or the robust Magpul MOE-TR stock for registered short-barreled rifles.
"Our company DNA includes numerous Marines, both active and former, plus countless professionals who've supported them in the field. As we celebrate the Marine Corps' 250th anniversary, our Devil Dogs conceived this special project as a fitting tribute. Our Cerakote specialists exceeded all expectations in recreating these historic patterns with museum-quality precision."
