I have five 350 barrels I will sell for $20 each as a group, double your money, lol.Build a .223 assuming the intent is to use an aftermarket barrel. At EO right now, buy a 350 Legend synthetic for $539 or 350 Legend Hunter for $579. The Hunter stock will get back $150 to $200. Sold one for $200, some are asking $300+. Better than the Beretta rebate. The barrel isn’t gonna fetch much but even $40 or so could put the buyer pretty close to cutting the cost of the complete action in half.
Just my math. To each his own.
