If you have seen different Remington 870 magazine extensions I think you have noticed that Remington original magazine extension is about 1 inch longer than the other ones: Choate, TacStar, Vang etc. I’ve heard so many different theories on why it is longer but the truth is that it allows you attach a bayonet to your shotgun!

You will need additional bayonet mount if you decide to add a bayonet to your shotgun. There are several variants of the Remington 870 bayonet lug mount.

The first one is made by the S&J Hardware. The price of this bayonet adapter is about $80-100.

The second one is U.S.M.C. M870 MK1 Bayonet Adapter/Magazine Bracket which was used by military and it is no longer produced. Sometimes you can find them on eBay or GunBroker for about $150-250.

Some people believe that bayonet is a useful addition to a shotgun. For example, it may be useful in Close Quarter Combat or Home Defense when you are out of ammo. Other use of it is a crowd control but I don’t think that many shotgun owners need this feature. :)
