Interchange parts between Remington 870 and 1100

[michaelsabre]

Knowledgeable members,

How many parts are interchangeable between 1100 and 870?

Stocks are the same, but that's all I know

Thanks!

The stocks will not interchangable on the guns, internals are different on them as well as the forend on the 1100.

Totally different.The only similarities are the Remington stamped in the metal.One is a gas semi auto, the other is a pump.

Some of the bits do exchange such as the safety and associated parts, extractor and associated parts, receiver pins, firing pins and springs, and assorted parts in the trigger assembly. There are probably others as well.
