I have my motorcycle for sale and someone is interested in doing a partial trade with this rifle, I was wondering its value. From what I know it is a Stag lower with a stark grip and CTR stock and a BCM upper with BCM BCG, Magpul rear sight and a Midwest industries rail. He said it does not come with the rds but comes with a traditional scope, which I really have no desire for anyway. It also comes with a little ammo, he didn't give a number so I'm guessing not much, it also comes with the case there. What do you guys think? He is wanting $1400 for it.
