ok a 2k1 cocker will run pritty sweet straight out of the box
first thing you need is a suitable air system ie, a high pressure one.
then you can start fiddling with everything else,
id go summut like this order
bolt - cant go wrong with the super charger (as found in eclipse and evo cockers. this will do a number of things including increaseing efficency, making the marker quieter and is more 'ball friendly'
trigger - next id work on the trigger, eather a roller sear and a trigger job on the standard frame or get an eclipse blade frame, nice and short.
3-way - a hollowpoint (as on eclipse) or similar 3-way will allow you to make your trigger even shorter and give a higher rate of fire
rex dialer - will allow you to adjust the velocity without taking the cocking rod out
valve - a super charger valve will give much better efficency and when used with a rex kit allows the use of lighter springs which will allow the mech to cycle faster and increase rate of fire
anything after that is for looks mainly, the stock ram and front reg onthe 2k1 cockers are easily good enough, the only reason to change the ram would be to get one that looks better than the stock brass one and the reg is as good as most after market ones
enjoy!
