Got one installed myself on 2009 poly easy to instal straight forward clear instructions. Havnt shot it yet since but from getting behind it in the basement wish it was a little higher. My own fault should of checked to make sure it was going to be high enough before drilling holes could of made it a 1/4 to 1/2 in higher would of been nice. For your info I have a arms 18 mount and a redfield 2-7 mounted as low as I can get it. I'll try and post some pics as soon as I can other then that it looks good and appears well made and delivered fast.
