Great scope
January 16, 2014
I bought this scope expecting it to be made of cheap rubber, it is the opposite. I do not know why it says rubber, mine is not rubber. It is a great scope. The ruby lens makes everything look bluish green but that is not a problem (it is actually pretty cool. It is a good size too. This scope is comparable to those that are expensive.

good scope

This is a scope that requires careful sighting in.
I am always amazed at the quality of these Chinese made scopes by NC. I am wary of Chinese quality control, and it's nice when the product is solid. This is one of them.
