the other possibilty that I can recognize from an issue with aftermarket nozzle for the TM hicappa which is a very similar design and has the same issue, the NPAS valve could be too big for the nozzle if either part is slightly off spec, and when the gun fires if it were to get stuck forward and not release any gas into the barrel, however, if htis were the case, after it doesnt fire some shots, the BBs that didnt fire would be rolling out of the barrel and not remain in hte mgas, is this the case? or are they still in the mags when its not firing?
