I can't figure out the cam lock! I get the part that the male part threads onto a 2" female thingy on the barrel......But with his Quadzilla he has it on his tennis ball barrel???!! How does he load the tennis ball then??? Because it really looks like he still has the 2" fitting on the barrel.....But a 2" fitting wont fit a tennis ball!!! So can someone please help me??!

thanks.

Correct. He doesn't breech-load the tennis balls.

if you want to use it for tennis balls then you can get a 2.5" banjo coupling but on the launcher he has he has many barrels. The banjo fitting is always on no matter how big the barrel is. He just can't use the banjo fitting for the tennis balls. So to answer your question he doesn't use the banjo fitting for the tennis balls.
