Do all tippmann paintball guns have the same barrel threads?

Answer 1

No.

The tippmann sl-74 I and sl-74II are threaded for sl-74.

The tippmann pro-carbine is pro-carbine threaded.

The Tippmann 98 is 2 different threads, they changed half way through production. An older barrel may not work on a newer gun because of tighter tolerances in the older stuff, but you can buy adapters if you happen to get into a jam like this. (Mostly you don't have to worry about this unless you get EXTREMELY unlucky)

Tippmann a-5's are threaded for a tippmann a-5 adapter witch then screws into the gun.

Tippmann x-7's are the same thread as a-5's.

Hope this helps!

Answer 2

Depends on the model of paintball marker you have. If you have a A5 or a X7, you can use a A5-to-Autococker thread adapter.
