I promised Tyler that when I had a chance to set this up, that I would give a full review. I installed the level and verified my crosshairs were plumb with a plumb bob line 100 yards away. Installation was super easy, no need to remove the scope, tightened to 15 in lbs and the level is super solid and looks good. I took my rifle and shot it at 600 yards and without looking at the level, I tried to determine if I was canted and I was. One thing abt this level that I think puts it above others to me is the stainless button under the bubble so u can immediately tell if you are centered, I really like that feature. All in all, I was well pleased, very easy to install, easy to use, looks good and quality is spot on. IMHO MK machining level is good to go and enjoy the snipershide discount, quality service and fast shipping.
