I am always amazed at the accuracy and simplicity of a peep sight. The ability for our eye to naturally center an object (the front sight) in the aperature is simply astounding. I guess that's why its been the choice of sight for militarys for years. Accurate and sturdy. I truly believe that I can shoot a peep as well as a low power scope out to at least the 50 yard mark.
Good job. I'm sitting in the AC today. No shooting for me. Right now it 95* in the shade.
