Guys, I am fairly new to AR's so excuse my lack of knowledge. But I was looking on PKfirearms website and noticed they had a "New from RRA" mid length 16" Predator pursuit upper and rifle. I have been debating between a new Predator Pursuit upper or a Coyote Carbine upper and thought, this is it. But my question is, what is the main difference between this mid length 16" and the regular Predator Pursuit. Is there anything that will affect accuracy or performance? What would be the pros and cons? Like I said, I am fairly new to AR's and was thinking the main difference between the 2 PP rifles would be the barrel length and the difference between the 16" PP and the Coyote Carbine is the flash hider. I couldn't find this on RRA website though. I figured it should still shoot since it is a RRA. Would this mid length 16" Predator Pursuit be the answer to my dilema between the Coyote and the 20" Predator Pursuit. Sorry for all of the rambling, but any help is greatly appreciated.
