Npas key

[joshcowin]

Hi their i have just bought a m4 gbb with a npas fitted but it didnt come with a npas key. Anyone point me into the right direction of what one i need, from what i can see the npas points towards the nozzle with a square edge? Thanks

There's a guy on Facebook which i believe makes them. i've had one from him before and it was great but not sure if he's still making them. i will ask him
