Most Helpful Positive Review .300 Blackout
Nice upper shoots very good with the Vortex spitfire I put on it. Would buy again if had another lower to put on it. Also the fit and finish on Aero products are very nice so was easy to assemble & get ready to shoot.

Aero, synonymous with perfection

by Richard, Verified Owner from NE, United States Written on February 14, 2025
I was debating on whether I should get a stand alone .300 rifle or an upper for a long while. I’ve had an unused lower for a while and eventually decided on this upper, and I’m glad I did. Initially I had a few failures to feed, but with a little CLP and a couple rounds down range that issue vanished all together. Sleek, lightweight and durable I’m glad I stuck with Aero as I’ve come to recognize their brand as quality.

If you’re on the fence, let this be your sign.
Pros:
  • Lightweight
  • Threaded barrel
Cons:
  • None

Very nice fit and finish.

by Darrell N Wyoming, Verified Owner from WY, United States Written on February 11, 2024
The upper came well packaged in a cardboard box with foam egg crate packaging. The quality of the materials seems high the fit and finishes very nice and I’m extremely happy at the moment. The only difficulty I had was getting the charging handle to seat due to the Cerakote making the Tolerances a little snug. After seating the charging handle it functions as it should. I haven’t fired it yet so that’s why the four star rating but I’m expecting good results
