Remember when Smart Parts sold 68ci fiber wrapped co2 tanks for the old shockers? Was that tank manufactured differently than regular 68ci n2 tanks? Would it be safe to install a co2 on/off valve on a 68 n2 tank and fill it with co2?
The only reason I'm considering it is for the old shoebox shockers I have... and some nostalgia. I realize that there are safety thresholds with things like this, but I was never sure if the marketed 68ci co2 tank skated in the gray area.
There were hybrid tanks made that were fiber wrapped but had a mixed co2/hpa valve. I just recently saw one at my field about a month or so ago. Confused the fill station worker for sure.
If it's a hybrid tank then it's okay. If it's another brand and is not rated/meant for/advertised as such, then do not do it. It becomes a large safety and liability risk.
Those Shocker tanks didn't have regs, just on/off shrader valves. They were also reverse threaded, they can't be used on a normal ASA. I didn't know any of that until I bought some old Shoeboxes and one of them came with it.
