They are for the T3x. The original T3 (2003-2016) shares the action but not the stock or trigger guard and is not covered by this manual, so do not assume these values carry over to it. Receiver-screw torque depends on the trigger guard: 7 N·m with a metal guard, no more than 5 N·m with a plastic one. Know which you have before reassembly. The Tikka/Sako muzzle brake for M14/M15 threads is tightened by hand, with no torque value; Tikka recommends a small amount of Loctite 278 on the muzzle thread and warns against letting threadlocker into the bore or onto functional surfaces. The manual's procedure names a TACT brake and its table a TRG brake, both at 8 N·m. It does not say whether these are the same part, so both are listed as written."
