Description
Aero Precision’s M4E1-T MOD4 14.5" 5.56 NATO Barreled Upper is built for durability, customization, and precision. The MOD4 13.5" handguard, crafted from 6061-T6 aluminum, offers a balance of strength and ergonomics, minimizing optical deflection under load. Its seven-sided M-LOK interface provides ample mounting options, while four QD sockets with steel liners ensure long-term reliability.
This upper includes a 14.5" 5.56 NATO barrel with a mid-length gas system for smoother cycling and reduced recoil. The government-profile barrel features a QPQ finish, a .750" gas block journal, and M4 feed ramps for enhanced reliability. A standard A2 flash hider is installed but not pinned or welded, making it ideal for customization.
