This upper is great shoots really nice and feels good. Quality is excellent!! Fit and finish top notch had no problems and was a nice tight fit on a Spikes stripped lower, couldn't have asked for better fit.

Everything is tight and well made. Small handrail provides very comfortable grip, and removing the flat top on most of the rail cuts a good amount of weight. I put this on a lightweight build, and have not been disappointed.

My second 14.5 aero upper, can’t go wrong. Aero thought ahead by using a slim muzzle break so you can swap out different gas blocks and hand gaurds. If you don’t want a tax stamp, 14.5 is the way to go. With pin and welded upper you get a shorter pro...

Product Info for Aero Precision M4E1 14.5in 5.56 NATO Threaded Complete Upper Receiver
This complete upper includes our ATLAS S-ONE Handguard! Our proprietary ATLAS attachment system is a durable and dependable mounting platform, maintaining a slim profile while still providing the strength and stability customers have grown to love from Aero Precision handguards.
We've taken the pain out of building a legal 14.5in rifle build. These pinned and welded 14.5in complete uppers feature an Epsilon 556SL that is permanently affixed to the muzzle providing an overall legal length of 16in. Worried you might want to change your gas block? No worries! The outer diameter of the Epsilon 556SL allows you to easily slide your gas block over the muzzle device making it easy to change or service your gas system.
If you've had a 14.5in build planned, but didn't want to deal with the hassle of getting it pinned and welded or being stuck with a specific configuration, then our 14.5 pinned and welded barrels/uppers are for you!
