Questions & Answers
am building an AR-10 in 6.5 Creedmoor. I have an aero precision lower and also looking to buy from here an aero 24” upper. Will this bcg work? Expert Answer

I would recommend going with a BCG that matches your caliber as to avoid any issues.

The BCG that’s listed as “silver” is it a nickel boron coating? Because the description also says all bcg are black nitride coated. Expert Answer

No Aero 'A' Logo
Machined from 8620 Tool Steel (Carrier) and 9310 Steel (Bolt)
Nickel Boron coated

Helpful Positive Review Matched set is good by Joe, August 25, 2020

Helpful Positive Review Great BCG for the Aero M5 by Jason, Verified Owner, March 2, 2024
Was doing research between Black Nitrite and Black Phosphate. The Black Nitride is more expensive but it's longer lasting and less cleaning needed. The positives out weighed the extra cost, so I ended up getting the Black Nitride. DEFINITELY RECOMMEN...
