Hey guys, if I were to breech mod my at2k with brass, how long should the 17/32'' barrel be?

Breech? I'm assuming you mean a nested brass? 9/16 and 17/32? It really depends on where your coupler is. If the coupler is attached directly to the valve piece, you need a piece to fit from the vavle to (atleat) 1/2" into the 9/16th when the barrel is on the coupler. Some people attach a piece of PVC, then a coupler, and then the barrel. This would require a longer 17/32, if you we're to use it.
If your talking about an Unknown breech, I'm not familiar with the use of brass in that design I assume you could have 9/16 sliding inside 1/2" PVC, overlapping the 17/32 piece when primed... could work.

Yes, it's an unknown breech.
