Customer service
I wrote a some what negative review earlier, (which did not appear anyplace yet) complaining about the very tiny sight from my green optic I ordered. I called the company to see if there was a plan 'B' because I knew I couldn't be the only one that thought the .040 was too small. For an additional $4.00 I ordered two, .125 green "Pre-bulbed" light tubes, which should work fine for me. They should be 3 times as big. Wish I knew about those earlier but that's my fault for not being able to find that on the web site, which to me is a bit confusing but I am not close to being a computer person. Another problem from being a grumpy senior citizen. Anyway, they were very helpful and I think this will do just fine. Nice company to work with.
