Ruger AR15 Stripped Lower Receiver - America's 250th Anniversary Edition

Commemorating a historic milestone in American freedom, the Ruger AR-15 Stripped Lower Receiver – America's 250th Anniversary Edition provides a rock-solid, military-grade foundation for custom rifle builds. Forged from high-strength 7075-T6 aircraft-grade aluminum and CNC-machined to exacting mil-spec tolerances, this limited-edition stripped lower receiver ensures broad compatibility with standard AR-15 upper receivers, lower parts kits, and aftermarket accessories. Protected by a matte black Type III hardcoat anodized finish, it delivers long-lasting resistance against physical abrasion, harsh environments, and chemical corrosion.

This special collector edition features a factory "Made in the 250th Year of American Liberty" engraving cleanly marked on the left side of the receiver. Engineered for maximum versatility and seamless assembly, the Ruger stripped lower incorporates a precision broached magazine well for effortless mag changes and a full-cut inlet fire control pocket that accepts a wide range of single-stage, two-stage, and match triggers. To eliminate receiver wobble, an integrated upper/lower tension adjustment screw is housed inside the grip tang, allowing builders to dial out slop for a custom, rock-solid lockup. Stamped with a "Multi-Cal" designation, this receiver serves as a patriotic blank canvas for builds ranging from standard 5.56 NATO carbines to .300 Blackout or 6.5 Grendel setups.
