I'm sorry I know this gets asked a lot. I always see "if the receiver has a M suffix it can shoot 3" shells"

It is a Remington "ShurShot" with a 26" barrel and remington 870 receiver.

The Receiver is stamped "RS#####D" and the barrel says "***12 GA. 2 3/4" and 3"*** 3 1/2" Only with Super Magnum Receiver"

It seems like the barrel is good to go for 3" shells but I am not sure about the receiver?

Thanks

I would call Remington. tell them what you have, give them the serial number, and ask if the receiver is a Magnum. My understanding is that NOT all magum receivers have an M in their serial number. Some of the earlier ones did not, if I correctly recall, but I may be confusing this with the P in early police models.

Thanks KlawMan. They aren't going to take calls until Monday, so I guess I will have to shoot 2 3/4" shells tomorrow duck hunting.

I'm tired and I probably mistook the meaning of your post so I edited what I first wrote. I am sorry I didn't have the easy answer for you.

While Remington says there should be an M in a serial number to denote a magnum receiver, my one year old 870 doesn't have one. It is numbered RS*****C and it has a magnum receiver.

How can I tell if my 870 shotgun has a magnum receiver?




If your 870 serial number ends with "M" you have a 12-gauge Magnum receiver that is capable of shooting 2 3/4-inch and 3-inch shells as long as your barrel is chambered for 3" shells

If your serial number ends with "A", you have a 12-gauge Super Magnum receiver that is capable of shooting 2 3/4-inch, 3-inch and 3 1/2-inch shells with a barrel that is chambered for 3 1/2" shells.

If your serial number ends in "N" or "U", you have a 20-gauge Magnum receiver that is capable of shooting 3-inch shells with the correct barrel.

You may also want to consider this from Remington:


Can I use a 3-inch barrel on my Model 870?

If I have a Model 870 barrel that is marked for 3-inch shells, can I use this barrel in my Model 870?

M

A

2 3/4", 3", or 3 1/2"



W

K, X

2 3/4" Only



U,N

J

H

.410

2 1/2" or 3"





The barrel and receiver design determines what can be shot from the Model 870. All barrels are clearly marked with chamber information located about half way down on the left-hand side, "side opposite ejection port". Receivers are marked with letters at the end of the serial number that determine ejection size.

These answers are over a year and a half out of date.

Have you tried unloading a 3" hull, including the primer, and hand feeding it into the chamber. Close the chamber and see if it ejects. You have to do this with a hull that has its crimp fully open.
