Apparently that seal didn't work too well. Almost all CW guns rusted out from the corrosive leftovers of black powder. The nitride is for corrosion resistance. In addition I'm trying a couple of different approaches to the gas seal hoping one of them will work with the mating tapered ring on the rear of the barrel. 8620 hardens well with a water or oil quench and will provide good backing for the nidride.
