What’s Included
- Aero Precision M4E1 Enhanced 5.56 NATO rifle with LaRue Tactical MBT-2S trigger installed
- LaRue Tactical MBT-2S two-stage trigger kit packaging (factory tin)
- Three 30-round polymer Thermold-pattern STANAG magazines
The M4E1 Enhanced receiver set features an integrated trigger guard, threaded bolt-catch pin hole, flared magazine well, and a receiver tensioning screw. These factory upgrades streamline assembly, improve durability, and tighten upper-to-lower fit.
The 16-inch 4150 CMV steel barrel is free-floated inside a 15-inch aluminum M-LOK handguard with a continuous Picatinny top rail. A 1:7 twist rate stabilizes heavier match bullets, and the threaded muzzle is ready for brakes or suppressors.
LaRue’s MBT-2S trigger delivers a crisp 2.5-pound first stage followed by a clean 2-pound break, providing a significant accuracy advantage over standard mil-spec triggers while maintaining a familiar two-stage feel.
Controls remain standard AR-15, with a manual safety selector, Magpul MOE pistol grip, and a collapsible polymer stock for length-of-pull adjustment. The direct-impingement gas system and forged 7075-T6 receivers keep the rifle light, reliable, and fully compatible with common parts and accessories.
Finished in black anodize and made in the United States, this rifle offers a balanced package of precision, ergonomics, and upgrade potential straight out of the box.
