The Sharps Bros. Heatseeker Select Chassis transforms the Ruger American STANAG rifle into a modern, streamlined platform. Machined from high-strength 6061-T6 aluminum and finished in matte black Cerakote, it pairs a rigid, lightweight chassis with a semi-fancy European walnut buttstock for a refined blend of performance and classic style. The 14" free-floating handguard with M-LOK slots on four sides offers generous space for lights, bipods, night vision, or ARCA rails while maintaining a slim, comfortable profile.

This model adds thoughtful shooter-focused details, including an adjustable cheek riser for proper eye alignment, QD sling attachment points, and a bottom accessory rail. Designed specifically for AR magazine–fed Ruger American STANAG models and compatible with both Gen 1 and Gen 2 rifles, it allows owners to upgrade their factory stock with no gunsmithing required. The Heatseeker Select showcases Sharps Bros. attention to fit, finish, and practical innovation for the precision-minded shooter.
