newguy23,
Welcome to AR15!!!
I purchased a RRA, about 2 weeks ago, for the same purpose you mentioned.
hI love Rock River Arms selections, price and quality. Depending on where in Ohio you're located, there's a gun shop in Sylvania, Ohio (just outside Toledo) called Adco Firearms, that sells RRA and has excellent prices. Check out their web site: http://www.adcofirearms.com and ask for Steve or Gary. They'll treat you right.
I would recommend spending some time on Predator Masters' web site too. Those guys will really help you with the calling, firearms, camo, decoys, etc. http://www.predatormasters.com
I ended up with a 16" SS barrel with a 1:8 twist and a free float tube over it. I don't regret getting a National Match trigger, as it's well worth the money. Also, I got a colapsable stock, which will come in handy when it gets real cold and you have on a lot of clothes, then I can adjust it down a couple of notches to fit, again.
Anything longer than a 20" barrel will become unhandy when hunting coyotes. Guys that have both barrel lengths, tend to pick up their 16" barreled AR to hunt coyotes.
I have a scope that will get replaced with a 3x9 Leupold (friend has it and wants to sell it cheap) or a 3x12 Tasco (44 Mag series). Scopes vary with the taste of the rifle owner.
Good hunting, Bowhunter57
