remington 11-87, scattergun tech 6shell sidesaddle, DMW easyloader, Tac-bolt handle, +6 mag tube extension, aluminum follower, and i've since added a 5" fiberoptic front sight (as well as a couple of reliability add-ons)
i can cram 10 2.75" shells in the tube (+1 in the chamber, grand total of 11), but loading 9+1 is significantly easier (and faster in most cases).
it'll dump em as fast as i can pull the trigger, and the gas system soaks up most of the felt recoil.
