We have just finished a small run of our original 'Shorty' shotguns. There are 3x that have been drilled and tapped in the factory locations for a Picatinny rail (rail included with purchse) ,1x that has no rail but does have the Scattergun Tech Ghost Ring sights installed and 1x that is the standard model (no rail only front fiber optic sight) Found here on the website :

If you would like to add the 'Performance Package' or anything else then just call the shop between 8-3:30, M-F and we will do out best to sort you out.
