Just two brands.
Simmons - 3-9x40 prosport - cross hairs canted on first 10 rounds - replaced by warranty. New scope has been good for 3 years and many rounds.
Leapers 6-24 scope. Put it on M14, bad idea. It held a 10MOA zero. I took off the scope and used irons - 3-4 MOA. I put the scope on a 22, same problem. I gave it to a neighbours kid for his pellet gun. The squirrels thanked me.
