I have a new barrel kit here and mine say A.691 and others. I was wondering what barrel thread that is

[Sirriko]

.691 is the bore size. Its most likely Auto COcker threaded.

ANyways, the bore size is the caliber (or size) of your paintballs. Match them up with a case to get best consistency. Check the barrel forums for more info in the stickies.

That's probably autococker threaded

take a picture of the threads? This guessing game is going to get pointless fast.


What gun did you buy it for?

if it actually says "A", though, it's most likely cocker threaded.
