Disassembly
Instructions
To properly disassemble an M1 Garand you need a slotted screw
driver, a needle nose pliers, a small punch, a medium punch, and
an M1 Garand Original Combination Maintenance Tool.
If you don't have an M1 Garand Original Combination Maintenance
Tool, you can find one at Midway USA .
1) Use the slotted screwdriver to pull trigger housing guard to
rear and then downward.

pulling down and away from the rifle.

from stock.

it's three main parts: 1) receiver and barrel assembly, 2)
stock, and 3) the trigger assembly.
5) Using the slotted screwdriver attachment on the Garand Tool,
unscrew the gas cylinder screw at the end of the gas cylinder.
The use of the Garand Tool is recommended to do this task
because of the size of the slots in the end of the screw would
require a very large slotted screwdriver, which most people
don't have on hand. Also the handle can be turned to a right
angle to the screw driver, which gives considerably more torque
than a normal screwdriver.

piston.

receiver, then pull up and then forward.

then you can pull up and out of the receiver.
13) Figure 15 shows the position of the rear hand guard, lower
band retaining pin. The barrel should be pointing to the right
to remove pin.
14) Use the medium punch to tap pin out of lower band, you may
have to use the small punch to finish guiding pin out of band.
15) Using the needle nose pliers - finish removing retaining
Pin.
