Its not as expensive as some, but not too cheap to be considered 'cheap.'  Anyone have any experience with them?  I am undecided as to the 'tube' type of dot sights like Aimpoint vs. the 'open' type like ATN or ACOG Reflex.  What would you choose?  (I have a 30mm BSA that I almost propped up down range today for a little .223 're-education' on how to be a red dot aiming device) [sniper]

A lot of people here bash the ATN site.  I dunno why  I have 5 of them.  None have yet to fail.  I prefer it over the OK and Bushnell.  The window is very narrow and keep peripherial vision clear.  Good sight, great price
