Who made your barrel?

YHM and Model 1 use the 1/2"-36 (ie 9x19) threading.

Its actually acomplete upper from Bushmaster. I thought it was 1/2-36 too. Maybe my 6.8 is different then.

My 7.62 x 39, 6.5G, and three of my four 6.8s are all 5/8 x 24. Only my DPMS 6.8 M4 style barrel is 1/2 x 28.

If it is a Shrub, then it is supposed to be 5/8"-24 thread.
