He MUST sell thru an FFL since he's unlicensed in MA. Since the gun isn't "grandfathered" or on the EOPS List, legally the MA FFL can NOT transfer it to another MA LTC holder. It must be sold only out of state. Doing that, he'll get next to nothing for the gun.
His best solution is to take a drive WITH a MA LTC holder to NH or ME (KTP?) and sell the gun to a NH/ME gun shop. He'll still get screwed but by a lot less than a MA dealer.
Another potential solution (check the rules here to make sure it is OK) would be for you to advertise it here as for sale ONLY to a NON-MA person and have an FFL ship it to the out-of-state FFL to transfer it. He'll get a lot more money for it that way.
