Bruce, this sight is not "Click Adjustable" in any way. It is an exact reproduction of Popes sight. The elavation is managed by moving two locknuts that bind against each other on a screw. The Windage is a left to right motion in a Dovetail managed by a Screw. There is a Vernier scale. The elavation is a pain. It has been said that Pope designed it that way on purpose as he felt many shooters were too quick to make sight changes. The Parts Unknown is exactly the same as my original Pope sight except it is better finished. Parts Unkown sends very clear directions on adjustments. Parts Unknown makes these with Bases to fit a number of Rifles. I know he makes it for original Stevens and I suspect that he will supply it with a Base with hole spacing for the CPA rifles if they in fact are different than the original Stevens. Sergio is a nice guy to tslk with and is quite knowledgable. HTH. Regards, FITZ.

What FITZ and marlinguy said about adjustment and the Pope.  I had for testing the very first example from Parts Unknown, and for looks and finish it was tops.  On the other hand the adjustment is cumbersome at best.

I would love to have a Pope tang sight on a gallery rifle that would not be adjusted a lot or perhaps even an offhand .22 for 100 yd schuetzen, but if I were thinking about BPCS or even CF schuetzen @ 200 yds, I think I would have to look elsewhere.  It's long on cool but pretty short on ease of adjustment.

I have an original Pope-Stevens on my Peabody Martini Kill Deer...yep, it's a pain to adjust for elevation, but windage is easy, and is used much more than the elevation adjustment.  Yep, it's a cool looking sight, on a good looking rifle!
