JT barrels and shockers

[Wouse101]

i got a Black center feed Shocker Turbo and a JT two piece barrel with it from shuck, it kept on coming loose during play. what might be the matter?

get a big o-ring and put it round the top of the threaded part so when you screw it into the gun, the o-ring holds it in place, stopping any vibrations making it come loose.
