Before attempting to disassemble the rifle for the first time, study the parts
drawing and parts list so as to be familiar with the relative position, appearance
and name of each part. Carry out the disassembly slowly and carefully note the
position of the part in the gun before starting to remove it. If a part is under
spring tension (such as, the Safety Selector, Bolt Stop, Trigger) remove it
cautiously 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 of
correct tension are vital to the safe and reliable performance of firearms.
Before
starting disassembly, remove the sling, scope and rings 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. CHECK TO BE CERTAIN THAT THE CHAMBER AND MAGAZINE ARE EMPTY.
3. To remove the bolt: Open bolt and pull to the rear while at the same time
pivoting open the bolt stop which is located on the left side of the receiver on
the right-handed version and the right side of the receiver on the left-handed
version. This is as far as you need to dismantle the rifle for a routine cleaning.
It is rarely necessary to proceed further.
4. To remove firing pin assembly from bolt: With bolt out of the rifle and firing
pin cocked, insert a pin or nail into the “disassembly hole” in the cocking
piece.
NOTE: The pin or nail should be as close as possible in size to the hole
diameter, and at least 2 inches long so that it can be used to ‘lever’ the firing
pin to the rear when reassembling the firing pin assembly into the bolt.
Unscrew firing pin assembly and remove from bolt. (Caution: Do not remove
the restraining pin until firing pin assembly is reassembled into bolt).
CAUTION: The firing pin assembly is intended to be a permanent
assembly and should not be disassembled. The parts are under great
spring pressure and if disassembled could fly apart with sufficient force to
cause serious injury. Also, special tools are required to correctly
reassemble this part.
5. To remove stock: Open floorplate and while holding it up out of the way,
loosen and remove the screw that holds the floorplate hinge assembly. Next,
loosen and remove the screw that is just forward of the trigger guard. Remove
trigger guard. Remove magazine box. (If magazine box does not come out
readily, do not force it. It can be lifted out with the barrel-receiver assembly,
but it must be done with great care.) Lift barrel from the stock very carefully.
Lift the receiver at the same time as the barrel is lifted so that the barrel-
receiver comes out of the stock level and not at an angle.
6. To remove the trigger: (Safety Selector should be in the “Fire” position.)
While holding the trigger in place, press out the trigger pivot pin.
(Caution: Trigger is spring loaded.)
