used this BCG in my Aero Precision 6.5 Creedmoor, have to say excellent BCG runs smooth never a cycling issue. If you're building an AR10 this is the BCG you will want!
The FailZero BCGs feel like a bar of wet soap in your hand. They are that smooth.
Beautiful finish, much nicer than the picture.

So I'll start off by saying that the bolt I received was much more polished than the picture, which is great because I was preparing to polish it myself to give it a nice shine. Its not a mirror finish, but its def a beautiful piece of steel.
