I have a Remington 6.5mm magnum model 600 .Does anyone know what this gun is worth. it has a 3x9 Simmons scope but i just purchased a 3x9x50 bausch&lomb for it. It also has a walnut stock it looks Beautiful.

There's a pretty good following for the 600's, especially in the somewhat rarer 6.5 and .350 magnums. I would think in terms of $500 or more for the gun alone, assuming proper condition.

Neither scope will enhance the attractivness of the gun. The Simmons is a "throw away" Asian scope, and the B & L with its hugh (and useless) objective bell is a gawdawful mismatch for a trim carbine.

Actually if your 600 is in excellent condition you could get 500 to 800 for it. Throw away the scopes and keep the iron sights. Scopes negate the usefulness of these carbines.
