I'll jump on this too, was given a creed to use at a tournament, unwrapped the beautiful box, took the bits out and put the barrel into the gun, attached my tank, aired it up...no leaks.
Off to the chrono with 5 mins to go before my first game, gun only shooting 200fps, wind reg a bit, up it goes to 275fps. Brilliant I thought. Turn air off and head to the field to start.
I walk to the netting, turn my air on and bang the gun explodes, the reg plugs itself 6" into the mud at my feet after breaking my finger that was holding it.
Not a great start to that guns life-in fact it was the end of it. Thankfully it was taken away the same day before it could hurt anyone else.
