700 ADL Long Action
Assuming the Remington SPS Tactical you are referring to is chambered in either .223 or .308, yes the SA (Short Action) stock will fit.

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.
