Hey all, first time poster and I have a question about my Remington 870 Wingmaster. It's a slightly older model, I think it was made some time around the late 70s early 80s. I love the thing but I want to remove the 30 inch barrel and replace it with a 18-20 inch barrel. I've heard that newer Wingmaster barrels are built to different specs, and won't fit. I don't think this would be true, but I figure it'd be better to ask before going through with any purchases. Thanks for reading.
