Hey Gotuve if your looking for a .223 semi auto battlerifle i'd take a look at the new SIG556 or the new Baretta Rx4 storm. I'd look into those before I bought a AR style .223. That's just my opinion. Oh another .308 semi that is worth looking into is the FN FAL if you are interested in .308 I'd look into that aswell as they seem to be pretty reliable and relatively cheap compared to their counterparts.
