RE: Reccomendations for an AR-15/10
Really Rock River doesn't have to be that much more expensive than the other brands. I got my RRA Tactial Entry model for 899 plus shipping brand new in pacakge on gunbroker.com. I could tell you the guy i got it from if you decide to go that way. He's a stocking dealer, and seems to have about everything in stock most of the time. That is 115 bucks below the price on the RRA website.
I love the gun. I did research forever before buying, and so many people that i talked to said that you can't go wrong with the Rock River Guns. Not knocking some of the other brands, i'm sure they make good guns too.
