Most Helpful Positive Review Functions flawlessly
The Fitment between this upper with my LWRC lower was good. Not tight, not loose. I put 300 rounds through it during one trip to the range. I shot 220g, 147g, and 124g rounds through it and there were ZERO issues. The rounds fed and ejected as expected. I dii ok T know if this is important for the review but Incase it is: I did swap my BCG and charging handle over from another upper I had. After inspection I found no abnormal wear or markings that weren’t present before use. I would definitely recommend this product.

Works Great

by Don, Verified Owner from LA, United States Written on November 1, 2021
Fits perfectly on my m4e1 lower and functions great. I like the handguard diameter, i have large hands and dont feel the need to put a forward grip on it, plus it helps keep it cool. Plenty of room for any type of adjustable gas block as well.

nice upper

by Bubba, Verified Owner from NC, United States Written on May 13, 2021
Came in shipped in about a week, brand new with no blemishes. Fits great with my standard aero lower. The barrel and muzzle device were properly oiled to prevent corrosion and packaging was snug to prevent any movement while being shipped. Can’t wait to go and shoot some subs with a suppressor.

Just what I needed

by MedicofKS, Verified Owner from KS, United States Written on December 18, 2019
This is a regular upper that I installed on an AR pistol platform. It mated and I have had no issues. The handguard is a little wider than I like, but that is a preference thing and not a function thing.

Aero 300 blackout upper 8” barrel

by Warrior Innovation, from GA, United States Written on December 4, 2019
Good look. Fits my lower tight. After having broke in the barrel it shoot a tight group. Runs great suppressed or not. Aero is always dependable. M-loks are a good fit. The finish looks good. Came with a 3” rail on top.
