Aero Precision APCR640441 M4E1 5.56 NATO 16" 31-Round FDE Carbine

The Aero Precision APCR640441 M4E1 5.56x45mm NATO 30+1 16" Mid-Length Barrel, FDE, 15" R-ONE M-LOK Handguard, Magpul Grip/SL Carbine Stock, Ambi Charging Handle/Safety is a duty-grade rifle engineered for high-stakes tactical environments. This professional-tier platform combines the reliability of a mid-length gas system with the advanced ergonomics required by modern law enforcement and military personnel. The Flat Dark Earth finish provides excellent signature reduction in arid or transitional settings while maintaining a durable, corrosion-resistant exterior. Whether utilized for patrol duties or home defense, this rifle offers a complete, out-of-the-box solution for shooters who demand precision.

Technical excellence is found in the M4E1 Enhanced Upper Receiver, which utilizes a proprietary integrated handguard mounting system to maximize rail rigidity and accuracy. By eliminating the standard barrel nut interface, the 15-inch R-ONE M-LOK handguard remains truly free-floated, preventing point-of-impact shifts when using a bipod or barricade rest. The 16-inch barrel is optimized for the 5.56x45mm NATO cartridge, providing the ideal balance of muzzle velocity and maneuverability. This combination of components ensures the rifle maintains a consistent thermal profile during rapid strings of fire.

Operators will appreciate the fully ambidextrous charging handle and safety selector, which allow for efficient weapon manipulation during off-side transitions or in confined spaces. The Magpul SL Carbine Stock and matching grip provide a streamlined, snag-free interface that facilitates quick mounting and a comfortable, repeatable cheek weld. This rifle is compatible with all standard AR-15 accessories and magazines, making it a versatile foundation for any mission-specific configuration. Its 30+1 capacity and threaded muzzle ensure it is ready for immediate deployment in any tactical scenario.
