I ordered a red and green u-763 and got them in 13 days from China. Went hunting last night and tried them out. The red one was ok, about the same as a kl 100, with a really tight beam. It seams to be good for shotgun or a small rifle. The green one is very bright, it will really reach out there. It was alot brighter than coyote tlr or klr 250....alot. I would say that you could id at about 250-300 yards. I was very impressed with the green one and not so much with the red one. Just my two cents.
