GENERAL INFORMATION AND MECHANICAL CHARACTERISTICS
The MMR
TM
is designed to operate with the ammunition caliber inscribed on the
barrel and as shown below:
5.56mm NATO can also re .223 Rem rie cartridges
7.62mm NATO can also re .308 Win rie cartridges
When the rearm leaves the factory, its metal parts are protected by a coat of
very adherent oil. This coating, especially inside of the barrel, must be removed
before using the rearm. The oil on the outside surfaces should also be removed
when the packing box has been opened because the oil is very sticky and it easily
retains dust and other solid impurities from the air.
WARNING
Because this rearm can be used as a single shot, it will re whether or
not a magazine is in the rearm if a cartridge is chambered.
FIREARM WILL FIRE WITH MAGAZINE OUT.
Be sure the cam pin is installed in the bolt carrier assembly. The rearm will
re without the cam pin and the rearm will explode, causing damage to
your rearm and may result in serious personal injury to the shooter and/
or others nearby.
Check your rearm for proper functioning before loading or ring live
ammunition.
This rearm could chamber a cartridge if dropped or jarred with a loaded
magazine in place and the bolt carrier assembly locked to the rear or in its
forward position.
When ring a large number of cartridges in a short period of time, the barrel
of the rearm will become extremely hot. If this rearm stops ring with
a live cartridge in the chamber of a very hot barrel, remove the magazine
and chambered cartridge immediately and allow the rearm to cool. This
rearm could re just from the heat of the barrel.
The MMR
TM
is designed to re semi-automatically. A single cartridge will re
each time the trigger is pulled. Finger pressure must be relieved from the trigger
before an additional shot can be red.
The MMR
TM
handguards are free oat tubes. Standard AR-15 / M16 type
magazines of various capacities will function in the 5.56mm NATO MMR
TM
. Use
Mossberg factory magazines or aftermarket magazines of the same style in the
7.62mm NATO MMR
TM
.
