Aero Precision M4E1-T Barreled AR-15 Upper Receiver - .350 Legend - 16" - QPQ Carbine - R-ONE 15"

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 16-inch .350 Legend QPQ-finished carbine barrel and a 15-inch ATLAS R-ONE handguard, ready for a bolt carrier group and charging handle.

Features:

• 16-inch .350 Legend QPQ-finished carbine barrel
• 15-inch ATLAS R-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 R-ONE handguard uses two mirrored, tapered locking nuts for evenly distributed clamping pressure and adds a full-length top Picatinny rail with an octagonal M-LOK profile. The carbine-length gas system keeps the package compact.

The barrel is machined for .350 Legend builds, a straight-wall cartridge popular for deer hunting. 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.
