I just purchased a new barrel for my older 20 Ga. shotgun. It won't fit, why?

Table of contents


Early Model 1100 and 870 20 Ga. shotguns were built on the 12 gauge. frame. The serial number on these shotguns end in an "X" or a "N". The barrel guide ring (gas cylinder) brazed to the barrel, was a 12 Ga. ring. These barrels are no longer available from the factory as they were discontinued in 1978. The barrels sold now are for the LT 20, which is built on a narrower frame. Its smaller barrel guide ring will not fit over the large frame magazine tube.

On our site we have a listing of parts dealers that may offer replacement barrels for your older 20 gauge under "Specialty Parts Dealers".
