PROVING THE FIREARM “SAFE”
•
•
•
•
•
•
Depress the magazine release [1] and remove the magazine [2].
Pull the cocking handle [3] fully rearward twice, then hold it to the rear.
Check to ensure that the receiver and chamber are clear; take control of any ejected cartridges and
return them to the magazine.
Allow the bolt carrier group to go forward under control.
Squeeze the trigger [4] to “Fire” the action.
Close the ejection port and place the fire control selector [5] on “S”.
8
15680S-EN
FUNCTION OF THE RIFLE/CARBINE
Your Diemaco firearm has a semi-automatic action. The action is cocked, with the chamber loaded and
selector lever set to “R”. The trigger is squeezed, the trigger rotates, disengaging the trigger sear surface
from the hammer. The hammer spring drives the hammer forward to strike the firing pin. The firing pin
strikes the primer in the base of the cartridge igniting the primer composition which ignites the main powder
charge.
High pressure gases push the bullet down the barrel where rifling grooves impart stabilizing spin to the
bullet. As a bullet passes the gas port (a small hole in the barrel below the front sight) gas is tapped off and
flows down through the gas tube into the bolt carrier chamber, driving the bolt rearward. As the bolt carrier
moves to the rear, the firing pin is withdrawn into the bolt while the cam track in the bolt carrier acts upon
the bolt cam pin, causing the bolt to rotate until its locking lugs are no longer in engagement with the lugs
of the barrel extension. The bolt is now unlocked and is carried rearward by the bolt carrier.
The extractor extracts the spent case and holds it against the face of the bolt. Once the spent case is exposed
to the ejection port the ejector then ejects the spent casing.
The bolt carrier continue rearwards, compressing the return spring and returning the hammer to its cocked
position, until the buffer assembly strikes the bottom of the receiver extension and stops. The return spring
then forces the bolt and carrier forward so that the bolt feed lugs strips the next round of ammunition from
the magazine and directs it forward into the chamber. Simultaneously, the extractor snaps into the groove
of the cartridge case and the bolt locks into the barrel extension. The hammer is now held rearward by the
disconnect.
[cont]
15680S-EN
9
FUNCTION OF THE RIFLE/CARBINE [cont]
When the trigger is released, the disconnect is rotated back releasing the hammer. However, before the
hook on the disconnect releases the hammer, the trigger sear surface has rotated in front of the hammer
notch so that the hammer is held on the trigger sear surface in the ready position.
THIS IS A SEMI-AUTOMATIC FIREARM. IT IS IMMEDIATELY LOADED AND READY TO FIRE AFTER
EACH SHOT UNTIL THE MAGAZINE IS EMPTY.
FUNCTION TEST
Test the function of the firearm after assembly, with the
magazine removed, as follows:
•
•
•
•
•
10
Cock the firearm; move the fire control selector to “S” and
squeeze the trigger: The hammer should not be released.
Move the fire control selector to “R”; squeeze the trigger
and hold it to the rear. The hammer should be released.
With the trigger still at the rear, cock the firearm: the
hammer should not be released.
Release the trigger and listen for a “Click” as the
disconnect releases the sear.
Squeeze the trigger again. The hammer should be
released.
15680S-EN
LOADING THE FIREARM
•
•
•
•
Place the fire control selector [5] on “S”. (Refer to figure on pg. 8)
Push the magazine [2] into the magazine well until the magazine catch [1] engages with a positive
“Click” to hold the magazine inside the magwell.
[Note: For loading your magazine please see the instructions for your magazine]
Pull the cocking handle [3] to the rear.
Release the cocking handle: DO NOT “Ride” the cocking handle, let it go forward on it’s own.
[Note: If your bolt is already in the OPEN position or to the rear, depress the bolt catch [6]. The bolt
will slide forward on its own pushing a cartridge into the chamber and lock the bolt.]
THE FIREARM IS NOW LOADED WITH A ROUND IN THE CHAMBER: THE HAMMER IS COCKED READY
TO FIRE.
•
USE OF THE FORWARD ASSIST - The Forward Assist helps to lock the bolt into the barrel. Use of the
forward assist will only be helpful on rare occasions, however when it is required it is a good indication
that it is time to clean your firearm. If the forward assist does not function using thumb pressure only,
thoroughly inspect the firearm.
Close the ejection port if you wish. This will open automatically after the first round is fired.
DANGER
!
NEVER LEAVE YOUR FIREARM COCKED AND LOADED WITHOUT THE SELECTOR IN THE “S”
POSITION. THE FIREARM COULD EASILY BE FIRED OR DISCHARGE CAUSING DEATH, INJURY OR
DAMAGE TO PROPERTY.

SIGHTS - ZEROING & AIMING
Some Diemaco SA firearms come with an Integrated Front Sight. If your firearm is an IUR there is no
integrated front sight, however most front sights whether Integrated or clamp on will work similarily for
elevation.
INTEGRATED FRONT SIGHT ELEVATION: The Integrated Front
Sight has an adjustable front sight post [1]. The front sight post
is moved up or down when zeroing the firearm based on Point Of
Impact (POI). First depress the Front Sight Detent [2], and turn
the front sight post clockwise to lower sight and bring POI UP.
Turn front sight post counterclockwise to raise the sight and bring
the POI DOWN. Once the firearm is zeroed, the front sight post
should not be moved.
Rear sights are not integral to Diemaco SA firearms. As all rear /
clamp-on sights are not created equally, please refer to the
documentation that came with your rear sight for care and zeroing
procedures.

15680S-EN
SIGHTS - ZEROING & AIMING [cont]
AIMING TIPS
• Relax, hold steady and keep firearm level. do not tilt the firearm sideways.
• Keep tip of front sight in centre of rear aperture sight. Focus on tip of front sight, not on target.
A. For Bull’s Eye target shooting, adopt a 6 o’clock hold on the black, and adjust the rear sight until
groups of rounds are centred on the centre of the bull’s eye.
B. For Point of Aim adopt a 6 o’clock hold on the black, and adjust the rear sight until groups of
rounds are centred on the 6 o’clock position of the black. This should make your point of aim the
same as your point of impact.
[Note: It can be difficult to see your front sight against the black of the target hence the reason we aim
at 6 o’clock.]

How to CLEAN
Materials: Cleaning rod or pull-through, cotton flannel patches, small toothbrush, quality gun cleaning
solution, lubricant, a brass wire bore brush and a brass wire chamber brush.
BORE AND CHAMBER
The rifle / carbine has lands and grooves called rifling. Rifling imparts spin on the bullet as it travels down
the barrel and exits the muzzle. Always follow the bore from the chamber towards the muzzle when cleaning
the bore.
[Note: Wire brushes should be used to clean only when required.]
•
•
•
•
CAUTION: ENSURE THAT THE FIREARM IS NOT LOADED
Use a pull through or cleaning rod with an appropriate size bore brush beginning from the chamber
down to and out the muzzle. The bore brush will follow the rifling in the barrel. Repeat as required. DO
NOT change direction while the brush is in the barrel as the brush could become stuck.
Apply cleaner / lubricant / preservative to a swab and pull through the barrel beginning from the
chamber down to and out the muzzle. Repeat as required.
Attach the larger chamber wire brush to the cleaning rod and dip brush in cleaning solution. Clean the
chamber by using a minimum of five plunging strokes and three 360º clockwise rotational strokes.
