WILSON 2 SHOT EXT 12GA REM 870 RH

Description

The Wilson Combat 2-Shot Extension Tube is a straightforward capacity upgrade for the Remington 870, 1100, and 1187 in 12 gauge. It is built for shooters who want more rounds available without switching platforms or modifying the receiver — the kind of pragmatic improvement that suits home defense, patrol, or range use equally well.

The extension is machined from aluminum and steel and finished in Parkerized matte black, a surface treatment chosen for its corrosion resistance and low-glare appearance rather than aesthetics alone. Included with the tube is an extra-power magazine spring, which maintains consistent pressure on the shell stack and reduces the chance of feed hesitation as the magazine empties. A high-visibility follower serves a functional purpose beyond feeding: its color lets you confirm at a glance that the tube is empty without needing to cycle the action or reach into the magazine.

A wave washer is also included to ensure proper seating at the barrel-magazine junction. One compatibility note worth understanding before installation: the follower is not grooved to match the detent found in newer 870 magazine tubes. Wilson Combat acknowledges this directly and notes that the detent in the tube can be filed down for proper fitment — a minor one-time task, but worth knowing before you commit to installation.

The right-hand designation refers to the sling mount orientation: the mount is positioned on the left side of the tube, placing the sling attachment point where it naturally falls for a right-handed shooter. If you run a sling on your shotgun, that distinction matters before you buy.
