Mossberg 400G compatible with ATI-FRG 6300?

[Graememcivor]

Hello,

I have a Mossberg Lakefield 400G 12G, I have been told that its the Canadian equivalent to the Mossberg 500. Can anyone confirm that this is true? Or better yet if the 400g is compatible with the ATI-FRG 6300 kit? Thanks

95% of the 500 and 400 parts are interchangeable. Stocks are compatible.
