I've got a Remington Express 12 gauge. It has an 18-inch barrel. I keep it loaded with 00 buckshot. It's pretty stock, except I did polish the chamber, replaced the MIM extractor with a Volquartsen extractor, and replaced the cheesy orange plastic follower with a Nordic Teflon coated, aluminum, low drag follower. I'm pondering putting a light on it, but haven't decided yet.
