MAINTENANCE

Your DPMS rifle is based on a military rifle design and is very rugged but proper

maintenance is necessary to keep it in good working condition.

Field Stripping Disassembly (Make sure your rifle is unloaded, with no ammunition in the

chamber.)

1. Bolt assembly should be closed in the forward

position.

2. Press the rear take down pin in from left of

lower receiver (it may be necessary to use a

punch as the fit between upper and

lower receivers may be very tight.) Pull

the pin out until it comes to a positive stop. A

detent keeps the take down pin from falling out of

the rifle.

3. Pivot the upper receiver and barrel assembly down

and away from the lower receiver.

4. Press the front pivot pin in from the left

side of lower receiver and pull out right side until

it comes to a positive stop.A detent keeps the front

pivot pin from falling out of the rifle.

5. You can now separate the upper and lower receivers. (Photo 25-A)

6. Pull charging handle to rear and remove bolt assembly. (Photo 25-B)

7. Remove charging handle by gently pulling it backwards until you feel a slight

resistance. Charging handle will fall free from the upper receiver. Do not force the

charging handle, damage to the charging handle wings may occur. (Photo 25-C)

8. Gently clean and lubricate the .22LR bolt assembly, but do not disassemble further

without first contacting DPMS.
