Overview

The Aero Precision M4E1-T Barreled Upper Receiver is chambered in 5.56x45mm NATO and features a 12.5-inch government contour barrel with a low-profile gas block and gas tube. Built with an enhanced forged upper receiver that provides a billet look, it features .250 takedown pin holes, laser-engraved T-marks, a full top Picatinny rail, and an installed port door and forward assist. The upper is equipped with an 11.4-inch MOD 4 M-LOK handguard machined from 6061-T6 aluminum. The handguard attaches via a steel barrel nut to reduce point-of-impact shift under load and features a 7-sided M-LOK interface, a 1.2" inside diameter, a 1.5" outside diameter, and steel-lined quick-disconnect sling sockets at the 3, 6, and 9 o'clock positions.
