A2 style HBAR

Love the barrel. The first one I bought had some issues but with the great customer service I got, they sent me a new one very quickly. Works perfect on my A2 build . I guess if I had one complaint, it would be that the twist rate is 1/9 instead of the military 1/7. But I still give it a 5 because I was very aware of what I was buying and it makes no difference to me.
