can not answer this with out looking at the rifle. Bore condition is key to value and bore scope is needed to give details.
Suggest you find a gunsmith to inspect this. Auction house that specializes in firearms can help.
What is the value of a Remington 29 T 32 barrel worth in great condition
Model ? Condition, condition, and condition ????
That would be a Model 732 2.5" barrel, Excellent condition $185-195 - add $25 for 4" barrel.
bought this revolver today seems to be in great condition
Hexagon barrel what? Model? pump, rolling block, ?? Condition?
The value depends on condition of the rifle and the model. IE scratches and dents in the stock etc... also how many rounds have been shot through the barrel. If your below 300 rounds there is still some barrel life left. Guessing you have an average model 70 no bull barrel or Coyote model 70 without a scope 400.00 to 500.00 if in great condition. However when ever I buy a used rifle that can shoot in the 3000 fps range I bore scope it first to see if there is barrel life left.
100-200 USD
Depends on condition, condition, and condition. If a model 12 which I assume since your not saying the model it's a early 12 and not marked. From 100 - 1,500 need condition.
$450-$600, depending on barrel, condition.
Depending on condition, $325-$375
150-175 depending on the condition and which barrel is on it
Depends on the model and condition.
