I had a RRA Tasc Rifle that I sold a few years ago because I wanted a flat top instead of a AR with the permanently affixed carry handle.  I also wanted to upgrade a few of my hunting rifles with better scopes, which I did.  Depending on how our tax return is, I might buy another AR.  It'll be used for target, plinking and sitting at the front of our gun safe in between to my 11-87 12 ga. (18.5" barrel, 6 shot mag) and my wife's 870 20 ga. Jr. model (18.5" barel, 6 shot mag).  It might see 500 or so rounds a year.  No type of competition, mainly a fun gun and SHTF gun.  I might get a longer barrel varmint type upper down the road.
 So my question is, does a Stag model 1 sound like an AR that will work for what we're going to use it for?  I'd get another RRA, I like the mid length hand guard, mainly because that's what I had before.  However, my dealer has a few Stag's for $800 to $840.  He'll more then likely come down a little.  RRA's seem to be harder to get.  They seem to have long wait times on their rifles.  He also has a couple of Smith & Wesson MP15's for $850.  I'm not sure which models they are.  They don't have front or rear sights.  I know they're not the Sport models. 
HERE is the model 1 I'm looking at. 
Thanks, NYH1!
