Remington 870/1100 Lightweight 20ga 8 Shot Extension (BLUED) +3 rounds


Remington 870/1100 Lightweight 20ga 8 Shot Extension


Increase your fire power of your shotgun with one of our magazine extension kit. These kits are constructed of solid steel and come with 1 Magazine Extension – (6,7,8, 9 or 10 shot), 1 Base Clamp (sling swivel loop pictured is no longer included), 1 High Visibility Shell Follower, and spring.

Using the 7 shot extension as an example shotgun capacity for a magazine extension is figured 1 round in the chamber and 6 rounds of 2 3/4 inch shells in the magazine tube. The new model Remington 870/1100/1187 shotguns have dimples that will have to be drilled out with 3/16 drill bit before the spring will extend up into the magazine extension. The older model Remington 870/1100/1187 will readily accept our extensions without any alterations. Find complete instructions in our FAQ section.

Some of the early 20ga Remington 870 shotguns were made on the 12ga frame so parts for the lightweight 20ga 870 will not fit. To determine if you gun is built on the 12ga frame remove your magazine cap and see if a 12ga shell will fit into your magazine tube. If the rim of the 12ga shell will not fit then your 870 is built on the lightweight frame, if it does fit your 870 is built on the 12ga frame. If your shotgun is built on the 12ga receiver then you will need parts to for the 12ga 870.
