I recently bought a used AR-15 (18" barrel) with a Flattop receiver and a Vortex Strike Fire Red Dot . I like the Strike Fire very much but I want to swap in a Scope from time to time for longer distances (up to 300yd). I've been shopping and reading around and it seems like a 1-4 power scope would do this very well for me, all I'm doing is target shooting. I don't have a lot of experience with rifle scopes, so if you think I would be better off with a different selection please let me know.
I've narrowed down my selection to:
Nikon M-223 (I'm not too fond of the center dot cross hair)
Leupold Mark AR (A tiny bit over my budget, but not by much)
Leatherwood CMR (It seems like a good choice considering cost/features, leaning towards this)
All of these are kits, I currently don't own a set of mounts, so I hope Burris makes good mounts. I've read good things about the Leatherwood CMR, and great things about Leupold as a company, but hardly anything about the M-223 series. Considering cost/features and assuming all these scopes are made with more or less the same quality, I'm leaning towards the Leatherwood CMR.
I would really like to hear your opinions, I'm fairly new to the AR and scopes in general
