The following specifications for the M77R Mark II Standard rifle are taken from the 2006 Ruger catalog: They appear to have been left 'as cast,' so the bolt travel is not as smooth as it should be. 350 Remington Magnum caliber is not very consistent, averaging about 5.25 pounds, but letting off anywhere between 5 and 6 pounds.Ī minor complaint is that the bolt raceways are not polished. Not so good is the replacement of the previous fully adjustable trigger with a cheaper lawyer inspired non-adjustable version. It is supplied with a pistol grip cap, rubber butt pad, detachable sling swivel bases, and cut checkering. The bolt is left in the white for contrast on the 'R' and blued on the 'RSM.' The walnut stock was designed in the 'modern classic' style. The barreled action of M77R Standard and M77MSR Magnum rifles is finished in a polished blue.

The bolt release is at the left rear of the receiver, and the three position (Model 70 type) safety is located at the right rear of the receiver. The Ruger Model 77 Mark II features a controlled feed Mauser pattern action with a flat bottom receiver and an integral recoil lug, one piece bolt, full length Mauser type extractor, fixed ejector, steel hinged magazine floorplate, generous ejection port for fast loading from the top of the action, square bridge action with integral scope mount bases, and an innovative diagonal bedding screw.
