Hey, i bought a used 98c with a flatline and rt... nice piece, but the screw that holds the flatline barrel tight (ie. the adapter screw) is missing.

Anyone know its size?

Don't know the size but you can check out tippmannparts.com or tippmannpros.com, they should have it. Or you could always call Tippmann, they have great customer service.

BTW, welcome to the forum.

You could take the adapter to the hardware store and find a screw that fits. It could be cheaper than ordering online.
