b. The frequency of disassembly and assembly should be kept to a minimum consistent with maintenance and instructional requirements. Constant disassembly causes excessive wear of the parts and leads to their early un serviceability and to inaccuracy of the weapon.

c. The rifle has been designed to be taken apart and put together easily. No force is needed if it is disassembled and assembled correctly. The parts of one rifle, except the bolt, may be interchanged with those of another when necessary. For safety reasons, bolts should never be interchanged.

d. As the rifle is disassembled, the parts should be laid out from left to right, on a clean surface and in the order of removal. This makes assembly easier because the parts are assembled in the reverse order of disassembly. The names of the parts {nomenclature) should be taught along with disassembly and assembly to make further instruction on the rifle easier to understand.

7. Clearing the Rifle

The first step in handling any weapon is to clear it.

To clear the rifle, first attempt to engage the safety. (If unable to place the safety in the safe position, continue with the second step.) Remove the magazine by placing the right thumb on the magazine latch and curl the remaining fingers around the front of the magazine. Press in on the magazine latch, rotate the base of the magazine toward the muzzle end of the rifle (fig 4), and remove it from the magazine well. With the knife edge of the right hand, pull the operating rod handle all the way to the rear, reach across the receiver with the right thumb, and press in on the bolt lock (fig 51. Check the safety to see that is engaged (position it in the SAFE position ii it is not), tilt the rifle, and look inside the chamber and receiver to insure that they contain no rounds.

8. Disassembly Into Three Main Groups a. The three main groups are the firing mechanism, the barrel and receiver, and the stock.

Figure 5. Locking the bolt to the rear.

b. After the rifle is cleared, the operating parts should be returned to their forward positions for disassembly. To do this, pull back on the operating rod handle, release it, and allow the bolt to go forward.

c. To remove the firing mechanism, grasp the rear of the trigger guard with the thumb and forefinger of your right hand and pull downward and outward until the mechanism is released I fig ill. Lift out the firing mechanism.

Caution: In withdrawing the firing mechanism from the stock, DO NOT rotate the trigger guard more than 90 degrees. Partial withdrawal of the firing mechanism, when combined with rotating the trigger guard more than 90 degrees, cause« damage to the rib rir key way s on the side of the firing mechanism housing.

<I. To separate the barrel and receiver from the stock, lay the weapon on a flat surface with the fights up and muzzle to the left. Grasp the receiver with the left hand over the rear sight and raise the rifle few centimeters. With the right hand, strike down on and grasp the small of the stock, separating the barrel and receiver from the stock. The components of the M 14 are shown in figure 7.

e. The components of the M14A1 rifle are shown in figure 8.

9. Disassembly of the Barrel and Receiver

Group a. Krmoving the Connector Assembly. Place the barrel and receiver group on its left side with the operating rod handle up and the muzzle away from you. On rifles modified for automatic firing, press in and turn the selector until the face marked "A" is toward the windage knob (fig 9). With the bolt closed, place the right thumb on the rear of the connector assembly, the first finger on the sear release bracket and the second finger inside the rear of the sear release bracket and the second finger inside the rear of the receiver (1, fig 10). Push forward with the thumb until the forward end of the assembly can be lifted off the connector lock with the thumb and forefinger of the left hand (2, fig 101. (Note that the rifle shown in 1,2, and 3, fjg 10 has not been modified for automatic firing). Turn the connector assembly (3, fig 101 clockwise until the elongated hole in the connector assembly is alined with the elongated stud on the sear release. Lower the front end of the connector asssembly and lift the rear end off the elongated stud of the sear release.
