Well built, flawless function thus far
I coupled this with an Aero pistol lower (came with their carbine buffer) direct from Aero Precision. I’ve run ... 11 different types of ammo through it including 3 subsonic loads, and have not experienced any malfunctions or failures as of yet. Subs cycle completely every time- she’s for home defense so I wasted a lot of $ proving this to myself. I’m only at a 450 round count so far, and will update if anything changes or if I win the lotto and go to town. The space provided for the forward grip is awesome. It’s very thin and I can get a complete grip on it. It doesn’t get too hot, but I cert...

Great deal
Quality is there, you can’t go wrong with this Aero Precision Upper, and the flash hider is a nice addition (even though removing it was a lot of work). Solid product, great deal and experience (fast processing and shipping).

Great upper
This complete upper (minus BCG and charging handle) makes any build easy.
No worrying about gas tube length or type of gas block to install. It's all done for you by Aero Precision.
Accuracy is very good with constant groups.
The only issue I had was my failure to clean the packing grease out of the star chamber.
This grease collected powder reside and kept the BCG from fully going forward. I did clean the barrel before firing but forgot about the chamber. My bad.
After a though cleaning I've had flawless functioning.
This is my second upper from Aero Precision and both have been stellar products.

Great upper for a suppressor host
This upper looks great. It has one of, if not the best rail Aero makes. It came in flaws condition, not scratches or scuff and everything is assembled tight with no wiggle on the handguard. The middle m-lok slot on the bottom isn't usable due to the gas block but it didn't affect the way i set up the rifle anyway. Makes a great suppressor host, specifically for the Dead Air Sandman S, the FDE colors match almost perfectly.
Very happy with this upper. A little pricey but I think it's worth it.
