Used Rem 1100 12ga, wooden stock.

Clean it form top to bottom, replace the O-ring on GP. Lube up with lube of choice. Cut the stock to fit. Cut the bbl to 18" or buy one of the factory 18" bbls. You're done, if you want to be a fast, minimalist, light-recoiling gun. If'n you want, add whatever accessories you think prudent.
