Decided I will be getting my first AR. I have about $1k to spend on a new (not used) rifle and don't want to build my own. I would like it to be a 16", 1/7 (or 1/8) with a mid-length gas system and iron sights. The only one I can find that meets those criteria are a Spikes Tactical Mid-Length. Are there any others in that price range to consider? Thanks.
