Hey all,

I did do a search so please forgive me if this topic has been covered.

What is the recommended torque value for the castle nut and barrel nut for the LM4? Real steel recommendations are +/- 40 ft/lbs for the castle nut and 35-80ft/lbs for the barrel nut. I dont want to break anything getting my accessories on/off, I will be using a proper armorer's wrench and a torque wrench for my mods. Thanks.

No clue on the exact torque. I just cinched it down till I was uncomfortable with putting anymore force on it. Plus a little extra to get my Noveske nut lined up.

Just tighten tight enough to fit the gas tube thru the nut.  (Really just like the M4 Carbine itself.  :) )
