The 5-20 and 10x are hd models. Glass is on par with the nxs, bushy dmr and gen 1 razors. Made by LOW Japan. Downside is it's skimpy on features. Basic reticle, no zerostop or rev indicator. Illumination is pretty meh too. Doesn't do the entire reticle. If you go the 5-20 route wait for cyber Monday or tax day. They will discount them to around 1k.
