I try to find information about this brand, i know it's made from Japan and I know they are making shotguns for Browning but no information about their scope ??
Don't know anything about them. The one thing in optics than I DO know about is YOU GET WHAT YOU PAY FOR! Cheaper price almost always means less quality. That has been a proven fact with optics for over 50 years.
Miroku scopes were made for the lower price point market. But they were excellent scopes in their day. I had 3 and not one of them fogged, changed zero, or caused any problems. https://www.ellettbrothers.com/
