I ordered this sight to complement my soon to arrive[
] FN P90TR. I'd never heard of this brand before but my research didn’t pop up any flags and the price was right. Anyway after unceremoniously cutting open the shipping box, opening the little product box and removing the packing material...out popped a short, fat, black tube thing. I was about to mutter something nasty when, by accident, one of the lens covers popped off. The sun coming through my GST's open moon roof hit the tube thing and a flash of golden amber reflected off the corundum (ruby) coated lens and hit my eyes...Wow, Cool! So I swallowed a little crow & decided to give the tube thing a closer inspection…
