Got the " Key mod and gas block installed . Color is off FDE

so I will recolor it at some point . May do the Pardus stock at the same time . The stock I really like costs about 1/3 of what I have in the rifle now . Not going to happen .
Rear sight is a bit to tall to fit under the scope other than where it is now ( see pic ) I can sight it but I have not used live rounds to see if it can even be done . I have a 1 inch rail and some low mounts but I have not tried them . I like where the scope sets now nice and close to the guard .
So what do you think about the BUIS placement ?
