Belomo compact multi reticle scope.
Belomo PK-06 multi reticle red dot sight. Gen.1 has a bit blueish glass compared to gen.2. There’s slight chip glare effect on max brightness. However, reticle is better visible in high contrast conditions. Actually, this is lighter and smaller version of Axion Kobra red dot, that keeps all it features. So, it can be called Mini-Kobra. This red dots weights only 90g (3 oz)! Mounts on Picatinny rail.
