I bought A RRA AR 15 from A gun shop saturday. They told me it was new & it had A chrome lined barrel. After talking on AR.COM, some folks told me to make sure it had the clb. I called RRA & they ran the #'s on the lower & they told me the lower was sold as A stripped lower . I called & talked to A friend who builds AR's & he told me what the gun shop did was illegal. Is this true ? When I called the shop & told them what RRA said, they told me to bring the gun back. About 5 minutes later they called again & said after some research they had made A mistake & put the wrong tag on the gun & sold it as A new gun. They said they have A new one just like it in the box & I could get RRA to verify the #'s & they would swap mine out. They also said the gun I have was built by someone & traded in. What would you do ? I want to swap the gun for the new one after I verify it's new, I'm just aggravated about the "mixup" Any advice ? Wanna kill these ads? We can help!
