Are they any good especially dusk or dawn ? What is a pp cross hair ? I haven't actually seen one or a -picture. I'm looking at optics planet.

I have not personally looked through a Pentax yet but being that they are a major player in the camera industry and make their own glass I'd imagine it would be a quality product. From the reviews I've seen at Midway and Cabelas that is is the general consensus.

I picked up one of their 4-12X scopes to put on my M1A, but, haven't gotten a good deal on mounts yet. Came in a set with a pair of 10X42 binoculars. The binos are nice...

My pentax dcf-sp binos are awesome, most bang for the buck of all the glass I looked through...
In my own comparisons, they beat zeiss, steiner, with ease....I think you had to jump to some swaro's etc...to beat them,

don't have any experience with pentax scopes though....
