I recently bought a C4 graphite 116 from Scubastore, and when i load it up the shaft gets lifted maybe 5mm up from the rail, its seems like the carbonfiberbarrel bends slighlty upwards when its loaded, and this would result in a inaccurate shot??? So i was just wondering if this is normal, or the barrel is damaged and therefore weakened. I use 2 14.5mm sigalsub bands at 350% stretch so its not like at would overpower it, and its not the shaft that is bent, i have tried several different ones.
 
5mm sounds a lot. There are other C4 owners on the forum (e.g. Magpie, Miles, ...) , hopefully one of them will be able to comment. Did you try contacting the reseller/manufacturer yet?
 
Hey, whats up! I have the whole line up of C4 guns, what shaft size you got in there? what make is the shaft? are you sure your wrapping it correctly? notched shaft or sharkfins, what mm is the shaft and length?

Hello, the shaft is a 7.5mm sigalsub 150cm shaft and its dead straight, even when the gun is not loaded the shaft has some clearence from the end of the shaft glider. so for me it seems the carbonbarrel is slightly bent in a upwards angle.
