Tritium Self-Illuminated Meprolight 21 Sight - No Batteries Required!

[GrewUpOnWesterns]

This Metrolight tritium reflex dot sight is so cool, day or night, no batteries ever required. A technological marvel. I bought it and by the time it was shipped to me, I had already had to sell my rifle and pistol, so never used it. Opened it to look at it, then boxed it back up, user manual, sight cover and box included. Bought for $499, selling as basically new for $299.
