I just received my A.R.M.S. 40-L SP sight and would like to know if the following is a normal attribute for this device. When open, the sight arm is canted slightly. The sight blades themselves also appear to be canted within the housing. When mounted on the rifle, I do have a clear view through it. So what's the story here, friends? "Out of whack, so send it back." or "Good to go, don't worry so!" Sorry the pics are so blurry, but a photog, I'm not! Thanks and Best!
