Any good red dots coming out of Japan? I have a love for anything made in the US or the former Axis Powers 🙈 Ironic aint it?
Depends what kind of 'red dot' you mean.
For tube assemblies, you have Ultradot (http://ultradotusa.com) which last time I checked were made in Japan. They also make a reflex sight, but it looks like it's for a pic rail.
I have two of their tube sights on my bullseye pistols, and the build quality is exceptional.
