you dont need tactical shit. that just adds $ to the price

get a remington 870 for cheap with whatever barrel you can find at a pawn shop then buy an 18.5" barrel and slap it on. takes 2 seconds.

i paid 170 for my 870 w/ a 28" barrel and spent 100 on an 18". you won't find an 18" for less than 270 unless youre lucky plus you get the 28" barrel for hunting and skeet.
