Hi... I have 177 m3... I need advice... My 1st reg is having creep... I put it in 160bar on 1st reg and 130 2nd reg... Few months before i have creep in 1st reg... And i change all the o ring in 1st reg and clean the brass piston tips with sand paper with various grid... After that the regulator is good... No creep, and fast refill.. After three months it started to creep again and slow refill... From 160 creep to almost 200 bar while the bottle pressure is 250... Anyone can help me? What can i do? Do the regulator must oftenly to repair again and change the oring? What is the problem with the 1st regulator? Do i have to change the Belleville washer too? I'm not often shot the gun, so the m3 will always stay on the drawer... Anyone can help?
