I currently have 4 ARs. One is wearing a 1-4x scope, 2 more are wearing aimpoint pros and the last is wearing the PA Dot. I have so far put about 500 rounds threw the rifle with the PA dot. I'm not law enforcement or military, former or otherwise. I just like to shoot and fell in love with the AR platform several years ago. Granted 500 rounds is not all that much but I think its enough for me to have a good idea if the PA will do ok. I like it a lot. I cant wait to take it to a carbine class or 3 this year. I would trust it on my HD gun. The previous model, not so much. Its a nice piece but the new one is sooooo much more.
