My buddy has a model 660, 6.5 rem mag at 90 to 100% condition. Does anyone know what this firearm will fetch?

THANKS

It is not possible to provide a reasonable estimate without at the least some good pictures.
The value of any gun, collector or shooter, is very condition dependent. Not to mention variations on any given model.
And finally and maybe most importantly the true value is only established when a buyer and a seller come to an agreement. All else is merely opinion. And maybe some guidance.
In my opinion.

I was just fishing, he's going to a collector on Friday and wanted a ballpark, my Bluebook says 100% $650.00
