The PR-SL-R-TI offers sliding (12mm from center) while also featuring a 360 degree rotating pyramid receiver, all with a low profile of only 30.5mm. This component is manufactured of titanium and is compatible with the European 4-hole pattern. The rotation is locked in place by tightening the 4 adjustment set screws on the receiver. The rotation is positively controlled in 3 degree increments with the use of interfacing radial serrations. The slide function is locked at the same time the four adjustment set screws of the receiver are tightened. If attaching to a PDI lock, torque the M6 bolts to 12Nm (9ft lb).
