Classic Army Mp5k - Air Nozzle Compatibility

[Bar1975]

Hey guys.. i want to replace my stock air nozzle with a proper air-seal nozzle but I'm having a hard time trying to find a nozzle specifically for an mp5k.

There does not seem to be a lot of options out there.. i replaced the nozzle on my M4 and there are hundreds of options but with the Mp5K I'm just not sure what size or model i need.

Would any standard Mp5 Nozzle work or are there specific nozzles for the Mp5k? Would i need to know the specs on my cylinder head to be able to match it with the nozzle or would that even matter?

I've read that the Mp5K has a very specific size nozzle and only that specific size will work?

can someone send me a few links maybe to compatible nozzles?

Torontoairsoft has a "bore-up" Mp5K Nozzle but not sure what effect the 'bore-up' will have? would i need a specific cylinder/cylinder head for this nozzle?

They also have a metal SHS Nozzle as well.. would that work?
