Aero Precision M4E1 Pro Rifle with 16″ Cold Hammer Forged Barrel

Built on the robust M4E1 Pro Upper and Lower Receivers, crafted from 7075-T6 forged aluminum, this rifle blends the strength of a traditional forged design with modern enhancements. The integrated trigger guard, flared magazine well, and fully ambidextrous controls greatly improve ergonomics. Its 15-inch free-float M-LOK handguard provides ample space for mounting accessories while enhancing accuracy by minimizing barrel interference.

An ambidextrous safety, bolt catch/release, and safety selector lets users with either dominant hand easily manipulate the controls of the weapon for even faster function.

The rifle’s recoil system is built with a mid-length gas system and a Heavy buffer ensures the M4E1 Pro delivers smooth, reliable cycling and reduced recoil for improved control and follow-up shots. The rifle includes an Enhanced Mil-Spec ALG QMS Single Stage Trigger, a comfortable Magpul SL Stock, and a durable anodized finish that ensures long-lasting protection and a sleek appearance.

The heart of the M4E1 Pro Rifle is its 16-inch barrel made from 4150 Chrome Moly Vanadium steel, finished with a durable QPQ coating for superior corrosion resistance and longevity. Chambered in 5.56 NATO, it is optimized for performance with both 5.56 NATO and .223 Remington ammunition, ensuring versatility for various shooting needs.

Made to be ready for duty, the Aero Precision M4E1 Pro is the next evolution of reliable AR-15 rifles ready to perform right out of the box for any shooter.
