no no no no. Do not get a single pane reflex sight... they SUCK to get hit in! I don't know how many direct hits they can take either, most of them aren't very sturdy. Get a 30mm red dot sight, tube style (forward and rear lens), they are extremely tough and can take an absolute beating... I've used one of mine for about 6 years and it's still going strong, zero issues, and many direct hits. I had a 40mm one take a few hits to the front lens and it eventually shattered, and my single pane reflex model I stopped using due to issues getting it clean (it would have failed eventually for sure).
