110BA Stealth stock and buffer tube specs?

Hey guys.
The 110BA Stealth. The buffer tube on it can be removed via a castle nut,correct?
And the thread on it would be the same as the AR-15 buffer tube thread, correct?

I know the Fab stock will fit on both milspec and commercial tubes.
But are the tube specs milspec or commercial?

The Stealth is on sale here so I might make the plunge this week.
I would like to put a Kynshot buffer tube on the gun to see if I can shot it without a brake. The Kynshot is milspec. Not sure if it will fit on the Stealth and stock.

Thanx for your help.

:^D

So to make it more simple.
Can the buffer tube be removed to put on a mil spec Kinshot buffer tube?

And is the stock buffer tube mil spec or commercial size?
