Ruger Model 77/50

Before taking the gun apart, set up to do it properly. Cover the work surface witha soft cloth so that the gun finish (and sights) will not be damaged, and provide atray into which the parts can be put as they are removed from the gun.It is preferable to carry out these procedures on a workbench or table which hasa covered top. A piece of shallow nap rug or an old, coarse blanket is an idealcovering. Such a covering not only reduces the chances of the rifle slipping andbeing scratched, but it serves also to trap pins, plungers and springs that mayotherwise get lost. It is advisable to have a container – such as a shoebox – inwhich each part can be placed as it is removed from the gun.Before attempting to disassemble the rifle for the first time, study the partsdrawing and parts list so as to be familiar with the relative position, appearanceand name of each part. Carry out the disassembly slowly, and carefully note theposition of the part in the gun before starting to remove it. If a part is underspring tension (such as, the Safety Selector, Bolt Stop, Trigger) remove itcautiously and anticipate the direction the spring and plunger are most likely to“jump.”WARNING: If a spring or plunger become lost, do not use a substitute. Springs ofcorrect tension are vital to the safe and reliable performance of firearms. See“Ordering Parts”, p. 39. Before starting disassembly, remove the sling, scope andrings and place the rear sight blade in its down flat position.DISASSEMBLY(Rifle Must Be Unloaded Prior To Disassembly)1. Keep the rifle pointed in a safe direction! Put the safety in the “load-unload”position.2. OPEN THE BOLT AND CHECK TO BE CERTAIN THAT THE RIFLE ISUNCAPPED AND UNLOADED. Run the ramrod completely down the barrel tomake sure the rifle has no bullet or powder in the barrel.3. TO REMOVE BOLT: Lift the bolt handle up. Depress the bolt stop on the leftside of the receiver. Remove the bolt from the rifle. (Before starting boltdisassembly, study Figure 21).4. TO DISASSEMBLE THE BOLT:a. While holding the bolt, rotate the bolt sleeve clockwise (as viewed fromthe rear of the rifle) to position shown in Figure 18, p. 24. The bolt sleeveshould be in the same position it is in when taken out of the receiver, butthe bolt sleeve may need to be rotated clockwise until the disassembly holeis fully exposed.23
