Aero Precision M4E1-T Barreled AR-15 Upper Receiver - 5.56 - 10.5" - S-ONE 9.3"

The Aero Precision M4E1-T Barreled AR-15 Upper Receiver combines an M4E1-T receiver, a billet-look enhanced forging machined from 7075-T6 aluminum with a new Picatinny profile, laser-engraved T-marks, and a standard threaded barrel nut interface with a 10.5-inch 5.56 barrel and a 9.3-inch ATLAS S-ONE handguard, ready for a bolt carrier group and charging handle.

Features:

• 10.5-inch 5.56 barrel
• 9.3-inch ATLAS S-ONE handguard
• M4E1-T enhanced forging with a billet look and a new Picatinny profile
• Low-profile gas block and gas tube installed
• Forward assist and port door installed
• Comes assembled; no bolt carrier group or charging handle included
• AR-15 platform with standard mil-spec fit
• Black anodized finish

The ATLAS S-ONE handguard uses two mirrored, tapered locking nuts for evenly distributed clamping pressure, with front and rear Picatinny rail sections and the center of the top rail eliminated to save weight. The pistol-length gas system keeps the package compact.

The barrel is machined for compact 5.56 NATO builds. This assembled upper saves you the work of fitting a barrel, gas system, and handguard, so you only need to add a bolt carrier group, a charging handle, and a muzzle device if one is not included.

Aero Precision brings aerospace-grade manufacturing standards to every receiver, barrel, and small part it builds, so components fit together without extra bench work.
