Whats this part called

[SteveGreenbaum]

Hey i was playing at paintball sams today and a part fell out which i couldnt then find. It is the part that goes between the barrel and the marker on a Bob Long autococker. I do not know what it is called or where to get a new one and it seems that it has made my gun keep breaking paint so it is essential.

It sounds like your talking about a breach sizer to me. They are not ecential(sp), but they do allow you to have different paint/barrel matches.

Hmmmm, where do you think i would be able to find a new one for my Bob Long Autococker. Without the breach sizer there seems to be a small gap inbetween the barrel and marker. Sorry for such a stupid question my sheridan nemesis which i upgraded from didnt have this part.
