I am new to the paintball scene, I have just aquireed an M4 RAP marker .43 calibre. It is not new, seems like it hadnt seen much action.
Unfortunately it is not working properly, I believe it is is down to the power adjuster, when I put but a co2 bottle on for the 1st time air ran straight through down the barrel, I stripped the action and regrease most of the seals, put it back together and now it holds air.
My problem is that the gun isnt firing, if I adjust the power brass thread and the smaller one next to it, it fires like in auto mode, is it down to the adjustment just beening wrong and how do I reset it back to factory as a starting point ? or is there something else wrong as to why its not firing wthout turning the air flow regulators and brass thread in front of it.
I am desperate to get this gun going as Ive had it two weeks and have put a 13cl guerrilla air bottle on it and a 203 greabade launcher but just can't mark anyone !!!
Any assistance greatly appreciated.
