Not a big fan of Iron Brigade Armory, basically all they do is take a Rem PSS or 700VS off the shelf gun do a little trigger job and put on a propriety paint job and charge an extra 1000$ for that. So you pay 2000$ for a gun you can buy at walmart.
Tac pro and Tac rifles.net actually do action work and use aftermarket barrels to ring out the best accuracy possible. Yes their 700 actions in AICS chassis but they've been machined to perfection.
Carney, I see you're in TX so if you're really serious about a good rifle there's a custom maker in Dayton by name of Charlie Sisk, he's in the same price range and can build you pretty much anything you want. And his rifles are MORE accurate than TacPro or Tacrifles.net.
