Re: Geissele SMR mkIV Barrel Nut: Is this normal?
Do you guys set the torque wrench to the torque spec provided? You guys know that you need to recalculate the torque setting when you use a spanner tool, right?
M1=M2 x L1/L2
M1 is the torque setting of the wrench
M2 is the actual torque applied to the nut
L1 is the normal length of the wrench
L2 is the extended length of the wrench (wrench + extension)
So if your torque wrench is 10 inches long and you have a 5 in extension, you'll set your torque wrench to 20 ft-lbs to achieve a 30 ft-lb torque.
