As the title says I am new to here. I am looking into getting my first AR. I am a casual shooter. I don't go out very often. I have read the stickeys for new users. Do you all like carbine length or mid length. I haven't really had a chance to get my hands on any. Also lightweight barrels or heavy barrels. I know i wont be putting an ungodly amount of ammo through at one time. right now I'm looking at the Del-ton kits and a spikes lower. Any advice would be awesome.
