Well I made up my mind and bought a RRA LAR8 thanks for your post . Now got to get some sights.

I'm new here this is my first post. I spent 20+ years in the US ARMY and went to the Gulf War in1991 so I'm not new to AR rifles. But I have never owned one and now that I've been retired for 10 years and Ar's have improved ,I am trying to figure out which is the best by brand and gas system. I'm leaning towards a gas piston based of years of use of the old gas tube I hated cleaning them. I also don't really want a 5.56. Any Ideas <munch>
