Well, let me see if I can answer that for you Zed. First off, when you say "a few bucks" we are talking about potentially $100 in savings for the 2 sets of sights I'm looking for. So, although I most likely won't have to worry about the sights being legit, I will have to worry about recouping the extra $100 I unwisely spent. Secondly and maybe more important, Aim does not have them in stock! But thanks for you input.
