Hello from Greece four months ago i bought an edgun matador 5,5 from finland and the gun was delivered in Crete. From the beginning was leaking air from the reservoire. After some advice from Ed and through the video included and because the service in Finland does answer me al all, i made myself the replacement of the big o rings. The destroyed o ring was the small inside the regulator so was also this replaced carefully. But now the gun shot very low about 670-700fp. Can someone help me about the right position of the regulator or what to do further? Or a shop that i can buy new regulator
