Design and Construction

The upper and lower receivers are CNC machined from 7075-T6 aluminum and finished with a hard coat anodize for corrosion resistance and wear protection. The RIS II handguard—also CNC machined 6061-T6—provides a continuous, rigid mounting surface for optics and accessories. Rail panels are Santoprene and heat resistant, offering tactile grip and insulation where needed. Polymer buttstock and pistol grip are finished with Soft touch overmolding for improved purchase under stress.

Barrel and Muzzle Package

The chrome moly vanadium steel, chrome lined barrel improves longevity and resists throat erosion under high round counts. The permanently attached flash suppressor is optimized for signature reduction and durability. The 14.5″ barrel with heavy phosphate coating balances maneuverability with effective ballistic performance for close-quarters and patrol scenarios.

Ergonomics and Field Use

On the range, the rail geometry and receiver fit-up translate to consistent sight alignment and repeatable accessory placement. The heat-resistant Santoprene panels are practical during sustained strings of fire, and the soft-touch overmolding reduces fatigue on extended drills. Priced at $1,935.99, this configuration targets shooters who prioritize component-level quality and factory assembly standards. View product details and pricing
