NEA muzzle device questions

[badboybeeson]

the finish was light grey like the threads. I did a quick cold blue on it and it discoloured from use. Needs another coat.

So what I'm gathering is that the big outer threads are for a QD supressor mount that wasn't adopted for use... I still would love to get some technical specs on the thread size and any other details.

Thanks for the helpful feedback.

you cant cold blue over nitrideing, that like painting over chrome and painting over glass
nothing is going to stick to is

Sorry, I must have been too vague asking about the specs on the threads. What I mean is that I'm looking to find out the angle, depth, distance between threads - the physical dimensions. Are those available anywhere? Who should I ask to find out?
