Hi, I'm new to this. I am building my first AR 15 I have 2 upper I'm look at the dpms oracle or the stag arms 3h. The dmps is not crome lined but has a brass deflector and is cheaper in price. Can any body tell me if they own or have used the stag 3h if it also has a brass deflector if so that is the upper I would like to go with. Thank you. And sorry for the noob ?
