The Wheeler Engineering Torque Wrench is a huge helper during assembly, which makes the job easier, especially when mounting optics. The torque wrench is a hand tool adjustable from 10-65 inch/lbs in 5 inch increments. The torque wrench is most often used when assembling rifle scopes or mounting rings on a bar, tightening screws in weapon systems and for tightening screws in covers/triggers or protected assemblies.
