LMT Defense MRP-H Quad 12.5" AR-10 Stripped Upper Receiver

The LMT Defense MRP-H Quad 12.5" stripped upper receiver delivers uncompromising modularity and durability in a compact, hard-hitting AR-10 platform chambered for 7.62x51mm NATO/.308 Winchester. Built around LMT's legendary Monolithic Rail Platform (MRP), this stripped upper features a one-piece forged 7075-T6 aluminum receiver with an integrated 13.25-inch quad rail handguard for maximum accessory mounting options, including lights, lasers, grips, and traditional iron sights. The quick-change barrel system allows users to swap barrels in seconds without tools, making it ideal for caliber conversions, maintenance, or adapting to different mission requirements while maintaining zero on optics and accessories.

This MRP-H Quad upper boasts a 12.5-inch chrome-lined, cold hammer-forged barrel optimized for maneuverability in close-quarters battle or suppressed configurations, paired with a low-profile gas block and full-length Picatinny top rail for secure mounting of magnified optics, night vision, or red dots. The monolithic design eliminates flex between receiver and handguard, ensuring consistent accuracy and reliability even under heavy sustained fire or adverse conditions. As a stripped upper, it requires only a compatible lower receiver, barrel nut (included or proprietary LMT), and standard AR-10 components to complete the build, offering builders flexibility to customize with preferred BCG, charging handle, and muzzle devices.

Renowned for its military-proven performance in demanding environments, the LMT MRP-H Quad 12.5" upper combines lightweight construction with exceptional strength, making it a favorite among professionals, precision rifle builders, and enthusiasts seeking a short-barreled .308 powerhouse. The quad rail provides versatile real estate for tactical enhancements, while the quick-change capability sets it apart from traditional AR platforms for rapid adaptability. This stripped upper represents LMT Defense's commitment to innovation, quality, and battle-ready reliability in every detail.
