I bought this scope to throw on my Knight TK2000 and see if I could extend the range of that bad boy even more. In fact it came friday in the mail. When that Sightron S1 went out, I was kind of mad. I am so careful with my scopes and stuff, and expect them take moderate abuse. Well this scope never took any abuse. And it was fogged full. So I took it off and sat there thinking, now I have to clean this rifle and I only fired one shot out of it... Then I remembered the Simmons 2.5 so I went and got the scope and tools and in five minutes was shooting again...
