The VLTOR Weapon Systems MUR-1A Modular Upper Receiver provides a rigid, Mil-Spec correct foundation for your AR-15 build. Precision-machined from aircraft-grade 7075-T6 aluminum with thicker walls than a standard upper, it delivers a stronger, more stable platform that enhances accuracy, reliability, and long-term durability. The flat-top Picatinny rail offers ample space for optics and accessories, while the integrated shell deflector and forward assist housing maintain familiar AR-15 ergonomics.

This upper receiver is ideal for shooters assembling a dependable rifle for range use, training, or general-purpose duty where consistency and longevity matter. Its M4-style feed ramps support reliable feeding when paired with quality barrels and components, and the hard coat anodized finish stands up to regular use and environmental exposure. As an upper-only component, it allows you to choose your preferred barrel, handguard, and internals, all built on VLTOR’s reputation for thoughtful engineering and meticulous machining.
