M14 barrel

up for sale is a never fired/never installed m14 barrel that was spun by norm Barnett of iron brigade armory. It’s a 4 groove 1:12 twist. I’ve contacted IBA and this barrel is worth around $1,000. I’m not looking to get that out of it, but I would like to get $500 or offer. Also, open to trades. Mostly looking for a high quality bipod, or an hk vp9 pistol, or let me know what you have.
