I bought a bone stock 870 Tactical at a pawn shop last month for $215 out the door. My wife and family came through on Christmas with some goodies for it... Magpul Stock Set, Magpul Sling mount, Mesa side saddle, and a XS big dot which works AMAZINGLY WELL on this model. I love a bead on a scattergun but this one is simply perfect for this gun. After selling the oem stock set, I am in this one for a grand total of $170 :D
All the mods took about 35 minutes total, but totally transformed this old beater. I'll add a simple sling and some sort of a light once I figure out which model I want to run and how. I might take advantage of the MOE mount for a Scout light, but I might try to keep it on the cheap with a Steamlight or G2 up front.
