Let me start by saying this is not a tool that every shooter must have. It is not even a tool that every long-range shooter must have, but if you are the type of person that likes to test and control for every variable in your shooting system, this may be a valuable arrow to add to your quiver. I like to compare the Scope Tool from Targets USA to a borescope as far as usefulness. 99% of the time you don’t need it and it sits dormant on the shelf. Fortunately, in the case of the Scope Tool, it has a nice aesthetic as it sits there. Then comes the moment when something isn’t quite right. You missed a shot at long range. You were certain you had the right dope. Your loads were perfect, with SDs in the single digits and ESs in the low teens. Your rifle is a tac driver putting holes on top of holes. Everything has been torqued and Loctited. What could it have been?

Maybe it was the scope. Believe it or not, minute errors in scope tracking can have a huge impact on results at long range. For example, last weekend I was shooting my .308 Steyr Scout at 1,000 yards. With my ammo and atmospherics, I had to adjust 414 inches above the target. If my scope had been tracking just 4% shy I would have impacted 16.5 inches low of my point of aim, which in my case would have missed the target completely.

So, how do you know if your scope is tracking correctly? This is when the Scope Tool finally gets a chance to spring into action. Well, spring may not be the right verb to use. Weighing in right around 30 lbs, the Scope Tool doesn’t exactly spring anywhere, and that is just the point. To put it simply, the Scope Tool is a heavy metal base with leveling feet and a 1913/Picatinny rail for the attaching of optics.
