The GG&G Remington 870 Mag Extension is easy to install as long as you have a working knowledge of how to break down your shotgun to perform maintenance procedures. These 870 Mag Tube Extensions attach easily without modification to the shotgun**.
Perfect for Military, Law Enforcement and Home Defense use.
Fits 12ga Remington 870, 1100 and 1187 shotguns only.
The 2 shot tube adds two additional rounds without increasing overall length of the shotgun.
The front of the GG&G Remington 870 two shot Mag Tube Extension does not protrude beyond the barrel of a standard 18.5" model.
The three shot Mag Tube Extension adds three additional rounds and will protrude approximately 2 1/4" beyond the barrel of an 18.5" model. IMPORTANT: It's important that you realize that having your Mag Tube Extension protrude past the muzzle may cause carbon build-up, scoring or discoloring to the mag tube extension, especially if you are using a ported choke tube. GG&G does not warranty this type of finish damage to the extension.
When installed properly, the solid steel ratchet base on the 870 mag tube extension nut, securely retains the barrel under recoil.
The end cap of the magazine extension tube can be removed separately to facilitate cleaning and the use of a magazine plug.
