Aero Precision is an undeniable powerhouse in the AR-15 world, and that legacy continues with the new M4E1-T ATLAS R-One Complete Upper Receivers. Lightweight but rugged, Aero Precision’s ATLAS attachment system is slim in the hand but maintains all the durability Aero Precision is known for. This upper comes assembled on an M4E1 threaded upper receiver with an 11.5” CMV 5.56 Barrel and includes a 9-inch ATLAS R-One M-LOK handguard. The new ATLAS R-One handguards are as function as they are aesthetic. These AR-15 handguards utilize 2 mirrored, tapered locking nuts that provide an evenly distributed clamping pressure across a custom barrel nut using a turnbuckle screw. QD sling cups are built into the side, providing an excellent base for a duty setup. With a carbine-length gas system and low-profile gas block, this upper receiver will function reliably even in difficult conditions. This upper receiver does not include a BCG or charging handle, which are necessary for function. Sights are not included, but a wide variety of sights and optics are available here at Primary Arms.
