Primary Arms does not provide a specific torque spec for their OpticsPlanet Exclusive 5x36 Gen III Compact Prism Scope. However, for most optics with an integrated rail such as this one, the recommended torque value of screw tightening is 40 in/lbs or 4.52 Nm. The Trijicon ACOG, for example, can be torqued to 44-66 in/lbs. You can also contact Primary Arms directly to see if they offer a recommended torque value for this optic.
