Aero Precision M4E1-T Features
The 18-inch 416R stainless steel barrel features a 1:8 twist rate, optimizing bullet stabilization for improved accuracy. The barrel is treated with a stainless steel finish, enhancing durability and longevity. A rifle-length gas system ensures reliable cycling, while the .750-inch gas block journal accommodates low-profile gas blocks.
The M4E1-T upper receiver is forged from 7075-T6 aluminum, providing strength without unnecessary weight. It includes M4 feed ramps and comes assembled with a forward assist and port door installed. The integrated handguard mounting platform simplifies assembly and enhances rigidity.
Paired with a 15-inch ATLAS R-ONE M-LOK Handguard, this upper offers ample space for accessory attachment. The handguard features quick disconnect sling sockets at the 3, 6, and 9 o’clock positions, built-in anti-rotation tabs, and a continuous top rail for seamless integration of optics and sights. The 1.3-inch inside diameter accommodates most muzzle devices and 1.5-inch suppressors.
A standard A2-style flash hider is installed to reduce muzzle flash.
