Operations Manual

.22LR CALIBER
SIGHTS
The .22LR bull barrel and the AP4 training rifle can have a scope, reflex sight or other
sighting device mounted directly to the Picatinny Rail on top of the receiver. The AP4 can
also utilize a detachable A2 sight or carry handle, and the DCM rifle comes standard with
national match A2 sights.
The front sight of both the DCM and the AP4 rifle is adjustable for elevation during zeroing.
Once zeroed, the front sight is not adjusted during normal firing.
The rear sight is adjustable for both windage and elevation, and can be easily used during
shooting to compensate for range and windage.
Although the elevation knob is the same as the one used on other DPMS rifles, you will not
be able to “battle sight zero” and adjust for elevation as you would with the 5.56. This is
due to the reduced ballistics offered by the .22LR. In order to adjust the rear sight for
elevation or windage, adjust the aperture in the direction you wish to move the impact of
the bullet. For example, if you are hitting left of your intended target, move the rear sight
to the right. If you are hitting low, adjust the sight higher, etc.
LOADING A MAGAZINE
CAUTION: Always check that ammunition is clean and undamaged before using.Loading
damaged ammunition into the chamber could damage your rifle and could
result in personal injury, death or damage to property.
1. Only use ammunition for which your firearm is chambered.
2. With front of magazine forward, place a round between the lips of the magazine with
the bullets pointed forward. Press the round until the magazine lips retain it. Place the
next round on top of the last and repeat until the desired number is loaded.
