Is there anyone that could help suggesting the proper torque value to tight the barrel extension on a AR15 match barrel?
Thanks in advance!

Just to make sure there is no language barrier...

Are you trying to screw on a barrel extension to a barrel?  (120ft/lbs)

Or screw a barrel nut onto an upper?  (30ft/lbs min. - 80ft/lbs max.)

I actually mean, screw on a barrel extension on a new stainless Krieger match barrel, just chambered from myself : generaIly I use the reference dot that Krieger provides on extension and barrel, but, this time I had to advance the extension a full turn on the barrel, to decrease a too wide radjus on chamber mouth.
Thanks for your help!
