Hello
´anyone knows what are the specification of the madbull Ace socom stock buffer tube screw?

Standard or metric

Should be M5x0.8 like all m4 buffer tube screws into spring guide (not #10x32 like many put in)

So it is metric....and is it 0.8 treads per inches ?

This is very kind of you for the info...
