c) Chamber Check

To do a fast chamber check, open the dust cover by pulling the

top of the dust cover plate outwards. The retention spring will

do the rest to open it. (Fig. c-1)

There is a chamber check window in the chute panel of the MDR.

Ensuring the MDR is on “Safe” and pointed in a safe direction,

insert the loaded magazine (bullets forward, Fig. b-1) into the

magazine well until it is seated with an audible “click” sound.

A quick tug down on the magazine is advisable to ensure it’s

locked in position.

Grasp the charging handle, press down and pull all the way to

the rear of the charging handle channel, then release. Do not

slowly release, or “walk”, the bolt forward, as it may not fully

seat the cartridge in the chamber.

The MDR is now loaded.

Press down and slowly pull back part way on the charging handle,

observing the chamber check window as you do so. As the bolt

face comes back, it will either be pulling a cartridge with it, indi-

cating the chamber is loaded (Fig. c-2), or it will have nothing

(Fig. c-3), indicating an empty chamber.

Once satisfied, release the charging handle back into battery.

It is advisable when clearing the rifle to do multiple chamber

checks to ensure the rifle is absolutely clear of any cartridges.

d) Firing

Shoulder the rifle by placing the recoil pad to the pocket of your

shoulder, and resting your cheek on the MDR cheekrest.

Follow all firearm safety rules when firing a weapon. Eye protection

and hearing protection is recommended when operating any firearm.

Permanent hearing and vision damage is very likely if ignored.

Grip the pistol grip with your firing hand, and the handguard

with your support hand. Use your support hand to keep the

rifle pressed to your shoulder, and keep your firing hand firm

but not tight on the pistol grip.

the chamber, which requires removal of the chute panel.
