No, the Remington Model 1100 stock has a hole (recepticle) through the inside of the stock in the pistol grip area to accept the action spring tube. The Remington Model 870 stock has no need for this hole so the 870 stock will not fit on the Model 1100 action.
The stock for this model gun can be found at cabella's
You will not likely find a Remington stock. I put my 722 in a Bell and Carlson stock and I love it.
They still make a synthetic stock for a model 700
No
No.
No, the re4ar receiver face on the Model 11 Remington has a different configuration. The Remington Model 11 is a semi-auto with a tube containing a bolt return spring located at the rear of the receiver. The Model 11 stock has a receptacle to accept this tube, the Model 870, being a pump action, does not have this receptacle.
I don't believe so.
According to Remington's website, that model was made 1928-1933.
There is no Remington Model 6 pistol, there has been however cases however of Remington Model 6 rifles converted to pistols by gun or "home" smiths. NOT Remington. As such the value is whatever someone will pay, but generally not much.
about $250 in clean condition
No, Winchester 1400
