Monte carlos stock for Remington 20 ga. 870
The official work from Remington 1-10-06:
Thank you for your inquiry. Yes, the butt stocks will interchange, the fore-ends will not. The same size stock from a current 20 ga 1100, 11-87, 870, 7400 and 7600 will all interchange. Also the older 760, 742 and 740 butt stocks will fit.
