The best tool to sight a scope in i have ever used
I have used a few different types of bore sights. And they do work.But after useing this sight and then fireing my guns 2 shots and i am dead on. Moved out two 200 yards 2 shots and i'm dead center of my target. 5 shots later and a Quarter will cover the 5 holes.
much better than my 7mm mauser one. this one has a nice on off slot where primer would be that is so far fool proof for not accidently turning on in your pocket.
