Well, I've been saving my pennies for a while now for a bull barrelled varminter. I finally decided to go the RRA route, with their 20" model. Went to a gun show Sunday, and found a dealer with two, a 18" and 20" take your pick for $750 plus tax. i just couldn't turn it down. So the more I inspect my new baby, the more I realize that it isn't exactly like the ones RRA advertises. It has a knurled, vented handguard, and a Double Star 1/10 barrel. I'm guessing he sold me a RRA lower with a Double Star upper, which is NOT what was on the tag, and NOT what he said. So, tell me, what would you do? Is Double Star reputable? I want an accurate rifle, and I don't think too much of "mixed" uppers and lowers. No offense to anyone who does. Should I try to get my money out of the upper and buy RRA? Thanks for looking.
