I had one failure on a bottle adapter and it was scary the force of bottle was like a rocket and broke my foot and I had a work boot on it also had a gage when went threw my celing . I remember filling it and heard a leak so I put my finger and it near my ear when it exploded , after contacting the manufacturer he said he had it made elsewhere and it may have been like cracked , all I know is I am lucky the gage didnt kill me and went threw sheetrock ,
Interesting how ED said about hand pumps , I never used one in 20 yrs but moisture does alot of damage to steel , I did not know it could cause havoc on alum as well ,
One question I have is this one of EDs guns or one of the guns built in other countries? I have read they making them other places even USA , I am only asking I am sure ED uses proper materials and would not question anything he designs , but when others co produce products I hope they use hi standards to materials
