Details:

Aero Precision is known for making some of the best quality AR-15 uppers. If you are building an AR-15, one of the best offerings from Aero Precision is the M4E1 Enhanced Complete Upper Assembly. It includes the upper receiver, barrel, gas system, and handguard, all made with precision and high-quality materials. To give you the best shooting experience and a reliable firearm.

High-Quality M4E1 Upper Receiver

The Aero Precision M4E1 Upper Receiver is forged from super durable 7075 T6 aluminum and precision machined. It has a matte black hard coat anodized finish. This receiver is a perfect platform for your modern rifle. One of the best features of the receiver is that the handguard mounting platform is forged into the receiver, which makes it more sturdy, and can result in a smoother shooting experience.

The upper receiver comes with a port door to prevent dust and debris from getting into the receiver and also features a forward assist like Military issue M4s and M16s. Moreover, the receiver also features M4 feed ramps, which improves feeding reliability.

Modern Slim Profile Handguard

This upper assembly comes with an Aero Precision Gen 2 Enhanced M-LOK Handguard. It has a slim profile, making the handguard very easy to grip and control. As far as attachments are concerned, you can mount anything you need on the M-LOK slots on the sides and the bottom of the handguard. On the top, you have a continuous top rail for mounting optics.

With a one-piece free float design and the built-in anti-rotation tabs, this handguard also stays in place and doesn't move or shift after rugged use.

High-End CMV Barrel

The Aero precision 14.5" pinned and welded upper has a 14.5-inch barrel and comes with a pinned VG6 Epsilon 556SL muzzle brake, which completes the legal barrel length for a rifle. The VG6 Epsilon 556SL features an aggressive chamber design, with two ports on both sides, which can vert gasses properly to reduce felt recoil.

The barrel is made from super strong and corrosion-resistant Chromium Moly Vanadium steel and has a QPQ finish. The barrel has 1/7 twist rifling and features an M4 feed ramp extension to work with the feed ramps of the receiver. It is HP and MPI tested to ensure that you get a barrel that will last a very long time and help you make accurate shots.

Low Profile Gas System

This Aero Precision M4E1 complete upper assembly features a low-profile gas block with a carbine length gas tube, which works great with the barrel and muzzle break that comes with the upper assembly.
