I picked up my first AR 15 (Stag Arms) at Bradis and started adding a few parts from the 1500. Now, I need some suggestions. I put on an Osprey International scope, but I will need a riser to clear the front sight. However, before I do that does anyone have any suggestions for a smaller scope that I can use? I like this one, but just may hold on to it for another project. Also, what sling should I look for at the 1500, tomorrow. Thanks in advance.
