Hey guys, I just ordered a both a holosun hs510c (red dot) and he510c-gr elite (green dot) for use on my AR and planned to return whichever I liked less. However, now I have been reading about the hs507c, and am wondering if I made a mistake. It seems to be smaller and lighter than the ones I ordered, but almost all of the pics I see of it show it mounted on a handgun. Is this optic not intended for rifle use, or more suited to handguns? Should I go with the 507c over the 510c https://tacticsfaq.com/holosun-510c-gr-elite-review/ ? Any help is much appreciated .
