Awesome looking and great shooting bcg
by Steve W.
Awesome bcg! I love the polish look and it shoots better than it looks. Shot 250 rounds the first trip without any issues. Thank you Primary for an awesome product.

Awesome bcg - I love the polish on it and it shoots very smooth. Shot 250 rounds on the first trip without a single problem.
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.
The FailZero BCGs feel like a bar of wet soap in your hand. They are that smooth.

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!
