give arundel militaria @    a go. they're legit, good communication, and they will pay you your money for a web/postal transaction. they won't give you as much as d&b but they are decent. with regards to d&b, they'll give you a good price, likely better than arundel. but, and here's a big "but"... if you're not doing a face-to-face sale, they'll likely want you to send it via courier with a false declaration of "car parts" etc as what you're sending. they'll want you to send it via the slowest postage to avoid airports. the point is most (if not all) couriers will not ships deac weapons via their services unless you're a registered firearms dealer. if for whatever reason you parcel is discovered, you'll lose you money. tl;dr try and sell to arundel militaria hope that helps
