Aero Precision M4E1 Pro Rifle 5.56 NATO 16" OD Green Rifle

The Aero Precision M4E1 Pro Rifle 5.56 NATO 16" OD Green represents the benchmark for modern direct impingement systems in both law enforcement and professional tactical environments. Designed for shooters who demand reliability without compromise, this rifle delivers consistent performance across diverse operational scenarios—from duty stations to training facilities. The 16-inch barrel length balances mobility with velocity retention, making it equally effective in confined building entries or open-range engagements.

Built on Aero Precision's proprietary M4E1 upper and lower receiver platform, this rifle features a flat-top design with integrated Picatinny rail for optics and accessories, eliminating traditional carry handle mounting complications. The OD Green finish provides superior corrosion resistance and reduced glint compared to standard black anodizing—critical in field conditions. The direct impingement gas system is engineered for reliable bolt cycling with standard 5.56 NATO or .223 Remington ammunition, while the free-floating barrel minimizes harmonic vibration for improved accuracy potential. Aero Precision's tight tolerances and quality control ensure consistent round-to-round performance.

This rifle is purpose-built for duty personnel, competitive shooters, and serious civilian operators seeking a platform with genuine military-grade engineering. The M4E1 Pro configuration accepts standard AR-15 components and most aftermarket accessories, enabling customization for specific mission requirements or shooting preferences. Installation of optics, rail-mounted lights, or furniture requires only standard AR-platform tools and basic familiarity with modular rifle systems. As a regulated firearm, transfer and ownership comply with all applicable federal and state regulations.
