Sounds like you want a good all rounder, this is similar my my first AR and i think it could suit you
RRA ATH carbine
1-8 twist barrel so you can use 70gr projectiles for deer, 18" quality match barrel - accurate and get a few extra FPS over 14.5" or 16", Nice 2 stage trigger - RRA is one of my favorite. Downside is that the heavy profile barrel and the hand guard will make it a bit heavy but its all about trade offs, you gain good accuracy and you have rails to attach anything you want to the hand guard.
