0.692 Barrel Back wanted

[Polar-Bear_Polo]

Hello fellow paintballers,

I have recently bought a marker and it only has one barrel back. This is why Im looking for an autococker thread barrel back with bore size of 0.692.
The barrel back has to be a barrel back not an insert. preferably the barrel back should be black and im not really fussed about what brand is it as long as it is heard of (planet eclipse shaft, dye Boom Stick, freak....). Im prepared to pay up to £40 and i would preferably like to collect it (I live near leeds, so cities like s****horpe or doncaster or retford wouldnt be a big problem).

Thank You in advance

Just a heads up mate you need to get a back that will fit your tip. Different brands have different threads etc. Do you know what barrel came with the gun?
