Remington Factory New 12ga Magazine Marine 2 shot Tube Extension Kit. Remington has never sold this as a Kit so as a Remington Master Gun Shop, I had to purchase the items from the parts list and make this kit up for all the correct parts. My last parts list is 2020 so I have no idea what the retail for these parts will be, however since the dealer price for the guns the new owners of Remington are selling is up 30% from the 2020 cost, I am guessing these parts would cost you around $156 if they even offer them. I am making the price $145.00 in good conscious.
I do not even recomend Remington Extension and I used the Wilson Combat ones on my customer guns unless the customer insisted on the Remington. Wilsons are Parkerzied so the Remington is the only Marine Coat. Some guys want what they want so here it is.
As of 11/9/2022 I only have 3 kits. Snooze you loose.
Note: They do not make this in 3 shot. Yes, it fits all 12ga 870 Models. If you have doubts call me at 231-690-0954
