INTRODUCTION
The SU-16 is a semi-automatic rifle chambered
for the .223 Remington (5.56mm) cartridge.
The SU-16 rifle will accept most standard M-16
type magazines. The forend can be unfolded to
form a bi-pod for more accurate shooting. The
stock has storage space for two 10 round Kel-
Tec magazines or one 20 or 30 round maga-
zine. By rotating the stock down and forward,
the SU-16 rifle can be reduced to a size of
27x7.5 inches (680x190mm) to facilitate
storage.
CONSTRUCTION
The receiver, stock, and...

The hot expanding powder gases drive the
bullet forward through the barrel. After about
.0007 seconds the bullet passes the gas port in
the barrel and some of the powder gases enter
the gas head and press on the piston. The
pressure builds on the piston, which pushes on
the piston rod and the bolt carrier causing the
bolt carrier to move backwards, unlocking the
bolt from the barrel extension. After the bolt
carrier moves about 0.41inches (10.5mm) the
bolt is fully unlocked from the barrel extension
and...

The hammer is now resting on the sear which is
pushing back onto the rear of the trigger block.
As the trigger is released the trigger block
rotates, lowering the rear of the trigger blockwhich allows the sear to move backwards and
rest on the top of the rear of the trigger block.
The SU-16 rifle is now ready for the next shot. 

INSTRUCTIONS FOR USE
The normal storage condition of the SU-16 rifle
is unloaded with the stock folded underneath
the barrel.
Folding and unfolding the rifle
To unfold the rifle remove the assembly pin
from its spring locked hole in the receiver. The
stock is simply latched onto the barrel with
friction and can be unfolded by simply pulling it
apart from the barrel. Fully extend the stock
and line up the assembly pin holes. Press in
the assembly pin until it is flush with the outside
of the stock
To fold...

unauthorized operation, other modes of storing
or carrying will gradually improve readiness at
the cost of safety.
Malfunctioning
Proper function of your SU-16 rifle is directly
related to maintenance and care, and to the
ammunition you use. Some of the more
common types of malfunctions which may
occur are as follows:
Misfire: A failure to fire or unusual sound upon
firing is always a signal to cease firing and
immediately examine the bore of the firearm. It
is not sufficient to just pull the operating...

or foreign objects impeding the magazine
follower. Improperly crimped cartridges are
another cause.
Failure to Eject or Extract: A fired case is not
fully extracted from the chamber or ejected
from the rifle. Again, keep the firearm pointed in
a safe direction, clear the gun by operating the
bolt, remove the case and continue. If neces-
sary, change the magazine. The most common
causes are a damaged extractor, ejector or
ammunition. Improperly loaded or sized
cartridges can cause this also. If any of...
