Jeep,

I assume you have a 12 gauge 1100? You could just buy a replacement steel shot barrel that will chamber 3" steel shotshells and can be used on your current frame. This would run you somewhere around $200-220 dollars.


Quoted from Cabela's regarding remington 1100 replacement barrels:

"All barrels have 2-3/4" chambers (except Steel Shot barrel). The 1100 Steel Shot barrel can be used with non-magnum receiver, you can shoot 2-3/4" magnum lead or steel or 3" steel shotshells. DO NOT USE 3" magnum lead. Used with a magnum receiver, you can shoot 2-3/4" magnum or 3" magnum steel or lead shotshells. The 1100 20-ga. lightweight barrels do not fit pre-1977 20-ga. guns with serial numbers ending in "X" or "N". "[/align][/align]KEJ[/align]
