My buddy is thinking of selling his stainless Contender in 7-30 Waters. He has had a wide range of estimates given to him ranging form $150-$900.00. It has a muzzle break, Burris 1-4 power scope, extra .22 L.R. barrel, and dies. Of course the guy that gave him the high estimate wasn't interested in buying it. Any thoughts? It would be in at least 90% condition.
