WARNING
To avoid accidental firing, BE SURE WEAPON IS CLEAR. Failure to do so
could result in serious injury or death.
Be sure the cam pin is installed in the bolt group. If it isn’t, your
can still fire and will explode, causing injury or death.
DO NOT exchange or switch bolt assemblies from one OA-93/OA-96 to
another. It could cause damage to both you and your weapon. DO NOT
attempt to install a standard AR-15 or M-16 bolt or bolt carrier in your
93/OA-96.
DON’T OVERHEAT YOUR
OA-93/OA-96
Firing
barrel to the
in the chamber for any reason may cookoff (detonate) in as short a period as 10
seconds.
If the cookoff point is felt to be possible, CLEAR YOUR WEAPON AND
ALLOW IT TO COOL.
Sustained rate of fire for the OA-93/OA-96 is 12-15 rounds per minute. This is
the actual rateof fire that this weapon can continue to deliver for an
length of time
Sustained rate of fire should never be exceeded except under circumstances of
extreme urgency.
If your bolt fails to unlock and you try to free it by banging the receiver assembly, keep clear of the muzzle.
If there’s water in the barrel, don’t fire the weapon. It could explode.
If you experience a noticeable difference in sound or recoil, STOP FIRING.
Either condition could indicate an incomplete propellant burn and a bullet still
in the bore. Retract bolt slowly and remove fired cartridge case. Clear weapon
and check for unburned powder grains in the receiver or bore, and for a bullet
in the bore. Remove unburned propellant or bullet from bore before resuming
firing or barrel could explode. If bullet is lodged in bore, take your carbine to a
qualified gunsmith.
If your
rel, remove the round quickly. If you cannot remove the round within 10 sec-
onds, point the OA-93/OA-96 in a safe direction and wait 15 minutes. In this
way, you won’t be injured by a possible ammunition
pen within 10 seconds after contact with a hot chamber. Clear your
93/OA-96.
Use only authorized brass case ammunition that is manufactured in the U.S.A.,
to U.S. specifications. Do not use re-manufactured or imported ammunition.
Please read this manual carefully before attempting to use your OA-93/
OA-96.
Any attempt to do so will cause damage to both you and it.

NOTE:
The OA-93 series is an amorphous firearm, available in a variety of barrel
lengths and (depending upon federal restrictions) available with or without a folding stock. For these reasons, the terms
sometimes used interchangeably in this manual.
The OA-96 is a distinct sub-species of the OA-93 family. While it shares
many parts and procedures with the OA-93 series, it is not available with
a folding stock, it has no magazine release sub-assembly, and the magazine is pinned and welded in place. All items referring exclusively to the
OA-96 are marked with a star

Operation Under Unusual
Conditions
NOTE
Unusual conditions are defined as any climatic
condition requiring special maintenance of this
weapon.
Perform the maintenance outlined for the climate
that most applies to your operational area.
Hot, dry climates are usually dusty and sandy areas. They are hot during daylight hours and cool during the night hours.
Dust and sand will get into the weapon and will cause malfunctions and
A.
excessive wear on component working surfaces through abrasive action
during the firing operations.
B.Corrosion is less likely to form on metal parts in a dry climate; therefore,
lubricate internal working surfaces only with a small application of cleaner, lubricant and preservative (always shake CLP prior to use). Do not
lubricate external parts of the weapon. Doing so will only collect dust
and sand, making it more difficult to keep the OA-93/OA-96 clean. Do
not lubricate internal components of the magazines, or the magazine well
on the OA-96.
C. Using additional equipment
protective bags and overall protective cover will help keep dust and sand
from getting into the OA-93/OA-96. Use these items as the situation warrants. As a minimum precaution to keep dust and sand out of your
weapon, keep the ejection port cover closed, a cartridge magazine
installed, and a muzzle cap on your OA-93/OA-96.
NOTE: Before firing, remove the protective cap and keep for later use.
However, it is not dangerous to fire the weapon with the protective cap in
place; the cap will blow off when the first round is fired and may be lost.
HEAVY RAIN
Perform maintenance according to the appropriate climatic condition. Use
additional equipment
and over-all protective cover as the situation warrants. Always keep the
OA-93/OA-96 dry. Using the protective cap will help keep water out of the
barrel. Always drain any water from the barrel before firing. Dry the bore
with a swab and cleaning rod, if necessary
