Bore Obstructions Warning

Before loading or shooting the rifle, be certain (he bore is unobstructed. Firing the rifle with any obstruction in the bore may result in severe damage to the rifle and serious injury to the shooter and other persons nearby.

If you suspect the rifle may have excess oil, grease or cosmoline in the barrel, or if it may have been exposed to humid conditions which could cause condensation, or to rain or snow which might have entered the bore, inspect the bore visually to be sure that it is clear.

A gun user should know that a lodged bullet is a common form of bore obstruction. Therefore the following information on how a bullet may becomc lodged in the bore, and how it should be removed, deserves careful reading and heeding!

1) A bullet may bccome lodged in the bore if (assuming the trigger has been pulled with a live cartridge in the chamber) the cartridge contains no powder, or the powder fails to ignite, and only the primer charge ignites, resulting in insufficient force to propel the bullet out of the bore.

2) A bullet may bccome lodged in the bore if, in unloading an unfired cartridge from the rifle, the cartridge case only is removed, thus leaving the bullet lodged in the bore.

The two conditions described above occur most frequently with reloaded ammunition but, however an obstruction occurs, proceed as follows, with the rifle pointing in a safe direction:

— Open the bolt and, if present, extract the cartridge case.

— Any cartridges in the magazine should be removed by releasing the floor plate (by pressing on the magazine latch) and catching the cartridges as they drop out of the opening.

— Insert a proper size cleaning rod (without a tip or brush) into the bore from the muzzle and remove the bullet. If the bullet does not readily dislodge, it may be necessary to lightly tap the handle end of the cleaning rod. Do not attempt to remove a lodged bullet using a blank cartridge, or a cartridge from which the bullet has been removed, or by any means other than the use of a cleaning rod. Be certain all loose powder has been removed from the bore and action before inserting the rod.

After removing the obstruction, reinspect the bore to be certain it is free of powder particles or other debris. Clean the mechanism of unburtied powder grains.

REMEMBER: Always check the bore for an obstruction if you experience difficulty in chambering a cartridge, experience a failure to extract, have a misfire, or the rifle does not make a normal loud report on firing.

A misfire or unusual report is always a signal to cease firing and immediately examine the bore of the firearm. Inspcct the bore visually—and with a rod if necessary — to be certain it is completely clear of any obstruction.

CAUTION: CHECK THE SERIAL NUMBER OF YOUR RIFLE BEFORE PROCEEDING. The information on this and several of the following pages applies only to PA-77 rifles which have the serial number prefix "79-" followed by the number 50000, or above. This includes all 3 digit prefixes, beginning with "77000001If your rifle has a serial number below "79-50000", do not use this manual Please telephone or write us giving the full serial number of your M-77 and an applicable Manual will be sent promptly.

The M-77 safety buiion can be moved to the safe position ("S" showing) only when the firing pin is cocked. Fully raising the bolt handle cocks the firing pin. The bolt handle can be fully raised and lowered (and the bolt can be opened and closed) when either the "F or "S" is showing.

The cocking piecc section of the firing pin protrudes from the rear of the bolt sleeve when the firing pin is cocked-as shown in Figure 1. This protrusion serves as a cocking indicator which can be felt as well as seen.

NOTE: When the safety button is positioned so the "S" is fully showing, the safety is said to be "on" (safe). When the safety button is positioned so the "F" is fully showing, the safety is said to be "off' (ready to fire).

When the rifle is loaded, unless it is to be fired immediately, THE SAFETY SHOULD BE AT ITS EXTREME REARWARD POSITION with the "S" fully showing. When operating the safety button (with the thumb) the user will feel additional resistance to movement of the safety before it rcachcs its extreme rearward position. That resistance should not be assumed to indicate the safety button is in the safe position.

WARNING: The safety is not on safe until it is 'clicked' into its extreme rearward position and the "S" is fully showing. Practice (with an unloaded rifle) moving the safety button into the safe position until you know by feel and sight that it is correctly positioned. See Figure 2 and Figure 3.
