I have a Shorty buttstock from RRA that is the compact model for easy manuverability, especially when wearing a tactical assault vest or armour. This Buttstock is complete with spring, buffer tube and all screws. It has a sling mount as well.
Trades? I'm only looking for some brand new black teflon DPMS mags or a Tango Down Foregrip.
