It's not like a Leupold in a one piece mount, but it's a lot more robust than you might think.
Zero is zero, and the adjustments are right there for you to see and verify.

I have and use different other rifles here, some modern things with rocks and mud durability.
This one is a lot of fun for the vintage aspect of the setup.
I like it. It's not a 35mm tube Steiner Military, but it's right for an accurate and handy field rifle.
