Thanks for all your input guys, I have sent another e-mail to BCM letting them know the rear sight is 29 clicks left of mechanical zero to line up. I can see no issue with the Magpul by just looking at it. However as one of you mentioned, it is plastic. For that matter, I can see no issue with the FSB by just looking at it either. I will upgrade this as soon as something better can be ordered and recieved. I am determined to put together a quality weapon as I am in pretty deep already. The red dot I used is just a cheap bsa I use on a shotgun, I just wanted to put something on there to see what it would look like should the need to use irons arrise.
