hi,
since a few month i have the Ares CO² mags for the DSR 1...
With 0,40g Mad Bull BB`s i croned 175 m/s ... very hard stuff !!
With my normal gasmags and Yellow gas / 0,40g BB its between 130-135 m/s ..
now its a real powerfull Snipergun ..but with this power you have to keep distance of minimum 60 m.
