The Mk10 W is an early-run, large-frame rifle from Sons of Liberty Gun Works that blends SOLGW’s renowned build quality with long-range 6.5 Creedmoor performance. A slick-side billet upper, 20" polygonal-rifled stainless barrel, and SOLGW’s titanium-secured M89H handguard give this rifle a precise, purpose-built feel. Ambidextrous controls and a Geissele SDE two-stage trigger round out a package designed for accuracy-minded shooters who want battle-grade durability.

This Mk10 W variant features a billet upper with no forward assist and an integral ambidextrous bolt release, reducing weight and snag points while ensuring intuitive control from either side.
The 20" 416R stainless barrel uses polygonal rifling for extended barrel life and consistent velocity. It is threaded 5/8-24 for brakes or suppressors and secured by SOLGW’s titanium Drive-Lock barrel nut for rock-solid alignment.
SOLGW’s 15" M89H handguard is free-floated, aluminum, and locks down with a three-bolt interface. A full-length Picatinny top rail and ample M-LOK slots allow precise accessory placement without adding excess weight.
Shootability is enhanced by a Geissele Super Dynamic Enhanced (SDE) two-stage flat-bow trigger that delivers a crisp break and short reset, while ambidextrous selectors make manipulation familiar for either hand.
The rifle ships with a B5 Systems FDE adjustable stock and a Magpul polymer grip—providing a 13.0" length of pull and a stable cheek weld that complements the platform’s long-range intent.
