Re: NCstar scopes
I purchased a 42mm NCStar red dot sight several years ago for my 10/22. I liked the wide field of view, but the dot was impossible to see in daylight against a white paper target (and I have good eyes). This was simply the way the sight was made and wasn't due to weak batteries. Also, I never seemed to be able to shoot a decent group with it. I am humble enough to admit when an issue like this is my ability more than the equipment, but the sight just never seemed to work well for me. This experience with a few others taught me that the pricier red dot / holographic sights out there are worth what you pay for them. That doesn't mean that I can afford the latest and greatest.
There is another side to the story, however...
After I pulled the red dot from my 10/22, I got a 4x30 traditional scope, also an NCStar. This one was listed as the "tactical" model which I don't really care about, but it meant that the tube was shorter than most scopes, a feature I like. This scope has been securely mounted to my 10/22 ever since, and I can put 10 shots under a dime at 25 yards with it (told you the bad groups mentioned above weren't my fault).
With this scope, it's a lot of fun to run a golf ball up and down a hill.
Knowing is half the battle...
Of course, the other half is violence.
