Hello all. In the somewhat bear future i want to buy an AR 15 (in .223). The brand i am pretty much dead-set on is Rock River Arms. I do not have alot of money so im trying to keep it under 1k. I see they have a few models for that price. I am wanting to know, what is the "best" all-around rifle in that price range? Should i go with a Mid-Length or a Carbine? Some of the models im looking at are the Standard A2/A4, Mid Length A2/A4, and the entry Tactical. Thanks!
