Most Helpful Positive Review Beautiful piece!
The title says it all. Machining is immaculate, fits the AR I built and works well. Worth the extra $ in my opinion to get the "Pro series".
Most Helpful Negative Review 50 rounds before failure
Literally cleaned, oiled, and placed it in my most recent build. All aero precision parts. Went to sight in the rifle and 50 rounds in have a stoppage. Clear the gun and notice an extra spring and metal piece in my mag. Turns out the ejector and spring just decided they didn’t wanna be in the bolt a...

Burr on the end...

by EC, Verified Owner from WA, United States Written on October 8, 2024
Do not recommend. The end needs to be beveled or at least remove the burrs. When closing the upper, it left deep cuts in the buffer...very sharp. I buffed it smooth, but for a premium bcg, it should not cause damage to the buffer when closing the upper. Never had this issue with any of my other premium carriers...little disappointed since i really like Aero products.

slapped this in my 10.5 Aero upper and it works

by Christian Rilla, Verified Owner from MA, United States Written on September 16, 2023
No problems running this bolt carrier group in my newly built 10.5 inch SBR, over 200 rounds through the gun on its first range day and didn’t have any issues with it. I like it, haven’t had any issues with it. Will be buying another for my Aero M16A4 build.

I recommend and what's really different than the less priced one??

by Al, Verified Owner from NC, United States Written on June 17, 2023
Aero has hyped this one up to be better, and in comparing it to my other Aero BCGs, I honestly can't tell the difference physically. I haven't had the chance to shot it back-to-back with the non-PRO Series, and for what it's worth, until someone really proves the pudding, it's hard to justify the extra cost.

Seems to me Aero is just hyping a product that they've really done no adjustments to. Just a thought...
