If you are looking...

I just received an "Immersive" Prism site from Wes, at Airgun Archery Fun (Canada).

I bought the 5-30 version. For a fairly inexpensive site, this is really nice. Appears solidly made. Most prism sights only have an optical adjustment for the reticle. This has optical adjustment for both, the reticle and...the target. It makes both the reticle and the target very sharp. And yes, as with most prism sights, the reticle is very sharp with little adjustment. And as for those that have an "astigmatism" (as I do), the "prism recitals" are very sharp.

It was designed for air guns, but would most likely work well on a powder fire.22 also.

It comes with three bases for forward and aft adjustment. The bases have adjustment for MOA also !

The eye relief is pretty short, but once mounted, it's not a big deal on a non-recoil (minute recoil) airgun.

Just thought I'd pass this along for those needing, or like me, like to experiment.

P.s. - Don't let the Canada exchange, dollar value scare you away. Wes understands selling/shipping to a US address ! 
 
Several of us have posted about these scopes as of late. I got the 10x40 for my compact Impact and I love it. Nice clear optics with a decent Mil Hash reticle. The adjustable objective dials in very precisely as well. If you are after a fixed power scope, and can handle the very short eye relief this scope has, the Immersive line is a quite the optic.
