pmr - proto matrix rail
looking through i cant believe no one has asked if you'll have access to air or co2! if the sites your playing at use co2 then DONT buy a pmr, etek, ego, ion, pm7 or whatever else cause you'll have yourself a very expensive paper weight after 30mins of play. co2 is a crap way to power a marker but if its your only option then get a BT, tippmann, spyder mr1 or something which can handle the cold temperatures being put through it.
cant explain fully as time for work .. YIPEEEE
