Ruger 450, Thanks for enquiring..

1. DIAMETERS: (ocular 38mm) (tube 26mm) (objective 46mm)

2. Paralax is adjusted by turning the oblong handle on top of the elevation knob.

3. yes these claw uppers are soldered on to the scope body.

4. reticle is the heavier (makes it easy to use in low light, dusk and dawn!) pointed post with pointed posts coming from left and right. (Google search "german number one reticle" and look under images and many examples can be seen)

-the dent is VERY light and close up pics make it look worse than it is.

-the engraving is nicely done if you are mounting on a drilling, but if a rifle or other combo is to be used I had considered soldering a small plate over this engraving with the type and caliber of the weapon used. Actually if you colored the engraving with a sharpy it would virtually disappear!

-I would put the optics and light gathering capabilities of this scope up against any modern 6x!

Kevin.

PS, Kuduae, THANKS for info..
