Just get your acc. that fit the HK MP5-N barrel and u should be GTG.

Silencerco doesnt make a piston that I know of for my Octane 45 with that pitch. Ill call and ask about getting one cut though. If not Ill just buy an adapter. Or trash the idea and sell the barrel.

Sometimes a great deal turns out to be not so great a deal. U find out why someone is selling an item at such a great deal.

I would imagine it would be cheaper to get an adapter than to have SilencerCo cut you a custom piston, if they even do that.

I agree. I just called a handful of major aftermarket barrel manufacturers. Pretty much have accepted that fact that it was probably a custom cut thread job for a comp of some sort. Adapter manufacturers here I come!
