hey guys. I am a newbie when it comes to ar15's so any help would be appreciated. I just purchased a PWS MK110 upper for my SBR lower http://primaryweapons.com/store/pc/viewPrd.asp?idproduct=106&idcategory=11 . The upper has athe PWS CQB comp installed http://primaryweapons.com/store/pc/viewPrd.asp?idproduct=90&idcategory=6 . I tried removing it so I can install my YHM QD flash hider for my suppressor but the dang thing wont budge. Any suggestions on how to remove it? Thanks in advance.
