Why Choose the MDT XRS for Ruger American (Short Action)
Hybrid Accuracy + Comfort: A 6061-aluminum chassis core delivers rock-solid action support and repeatable zero, while the polymer outer shell gives a warm, traditional stock feel in the shoulder and on the cheek.
AICS Mag Ready: Accepts common AICS-pattern short-action magazines, enabling fast, reliable reloads and easy mag changes at the range or in the field.*
Tool-Less Adjustability: Dial in comb height and length of pull with user-friendly adjustments and spacers—optimize for hunting layers, optics height, and shooting positions.
M-LOK Everywhere You Need It: The forend features M-LOK slots for bipods, ARCA adapters/rails, QD sling cups, barricade stops, and other accessories.
Balanced, Barricade-Smart Forend: A flat, stable underside and squared shoulders help you load bipods and brace confidently on bags, posts, and barricades.
FDE, Done Right: The Flat Dark Earth finish pairs a stealthy, non-glare look with everyday durability and easy field touch-ups.
*Always verify magazine and cartridge compatibility and function with your rifle before match day or hunting.

Real-World Benefits
Consistency You Can See: Aluminum-to-action interface and a free-floated barrel help reduce point-of-impact shifts and stock flex—especially noticeable when loading a bipod or shooting from a tripod.
Faster, Cleaner Positions: The squared forend and flat underside ride bags well, while M-LOK/ARCA options make it easy to clip into tripods or add barricade stops.
Built to Travel: The hybrid shell resists dings and cold soak, while the hard-anodized core shrugs off the elements—ideal for match circuits and backcountry hunts.
Cross-Discipline Flexibility: Set it up light for a mountain rifle, or add a bag rider, ARCA rail, and big bipod for a match-day rig—one chassis, many missions.
