Kel-tec SU-16 Instructions Manual

							back to eject the round in the chamber. Do not
obstruct the ejector port and keep fingers away
from trigger and muzzle. With the operating
handle fully pulled back push up on the bolt
stop and slowly release the operating handle,
the bolt should stay open. Visually inspect the
chamber to make sure it is empty. Pull back on
the operating handle to release the bolt stop
and release the operating handle to close the
chamber. Push the remaining cartridges in the
magazine forward and out.
Loading
To load, fill the magazine by pressing a
cartridge downward on the magazine follower
(or downward on the previously loaded
cartridge).  Continue loading until you have
loaded the number of cartridges you wish to
load, up to the magazine capacity of 10 rounds.
Do not attempt to load your magazine with
more than the specified number of rounds.
Doing so can damage the magazine and cancause a feeding malfunction. Before inserting a
loaded magazine always tap the back of the
magazine against a hard surface two or three
times in order to properly seat all the cartridges
to the rear of the magazine.
With the rifle’s safety engaged, hold the rifle in
one hand with the muzzle pointing in a safe
direction and with your finger off the trigger and
outside the trigger guard.   Insert the loaded
magazine into the grip until it is locked in place.
Check to assure that the magazine is secure.
Pull the operating handle back and release.
This strips a round from the magazine and
seats it in the barrel chamber. 
						

							If you wish to restore the magazine in your rifle
to full capacity, press the magazine catch and
remove the magazine to load the missing
round. Remember to keep the safety engaged
and your rifle pointed in a safe direction under
all conditions and always keep your finger off
the trigger and outside the trigger guard until
ready to fire.
DISASSEMBLY
NOTE: Disassembly can be performed with
only a cartridge but a few simple tools such as
a small punch and small pliers can make things
much easier. A Phillips head screw driver is not
necessary for general maintenance and none ofthe screws on the rifle should ever need to be
removed for general maintenance.
Rifle disassembly
Unload your SU-16 rifle and cycle the operating
handle to be sure that there is no round in the
chamber.  Make sure the bolt is in the forward
position and the safety is engaged.
CAUTION: some accessories that are
mounted to the picatinny rail on the top of
the receiver may interfere with the disas-
sembly of the SU-16 rifle. It is advisable to
remove any scopes or other devices
mounted to the rail before proceeding with
disassembly. 
						

							With a cartridge or other pointed object push
out and remove the assembly pin. Fold the
stock down and forward and press it onto the
barrel. Unlatch the bipod.  Grip the recoil spring
tube, pull it towards the muzzle and twist it ¼
turn so that the locking tab points towards the
top of the rifle, it should slide into the receiver
about ¼ inch as you release the recoil spring
tube. Slowly pull back on the operating handle,
the recoil spring tube should also move back
and there should not be any spring pressure
felt. Pull the handle all the way back and push it
down into the operating handle removal cutout
in the receiver. The operating handle shouldnow be able to be pulled straight out of the bolt
carrier. After the operating handle is removed
the bolt carrier assembly can now be guided
out of the bottom of the receiver by holding onto
the recoil spring tube.
Bolt carrier disassembly:
To remove the bolt, cam pin and firing pin
simply press out the firing pin pin from the right
side with a small tool or a cartridge. Remove
the firing pin from the back of the bolt carrier,
you may need to tap the bolt carrier or move
the bolt in and out to get the firing pin to fall out
enough to grip it. With the firing pin removed
the cam pin can now be pulled out and with the
cam pin out the bolt can be removed from the
front of the carrier.
To remove the piston head, recoil spring tube, 
						

							and recoil spring first align the holes in the
recoil spring tube with the pin in the piston
head. While holding the piston head with one
hand, press out the piston pin with the firing pin
or a small tool.
CAUTION: the piston head is under pressure
from the compressed recoil spring and the
piston head and recoil spring can easily fly
out and injure yourself or bystanders,
always keep a hand on the piston head and
point the piston head in a safe direction
when removing it.
 With the piston pin removed the piston head isnow free to be taken off. Slide the recoil spring
tube off the piston rod and remove the recoil
spring from the recoil spring tube.
NOTE: It is not recommended that you
disassemble the stock of the SU-16 rifle; the
hammer spring is constantly under tension
and can easily injure you or others.
ASSEMBLY
Bolt carrier assembly:
To install the piston head, recoil spring tube,
and recoil spring insert the recoil spring into the
recoil spring tube.  Slide the recoil spring tube
with recoil spring onto the piston rod. Align the
holes in the recoil spring tube with the hole in
the piston rod. Push the piston head onto the
recoil spring and onto the piston rod. Insert the
firing pin or similar tool into the piston head
hole to temporarily hold the piston head in
place. While slowly pulling out the firing pin
push in the piston pin from the other side until it
is flush with the piston head. Twist the recoil 
						

							spring tube so that the locking tab points
towards the top of the bolt carrier. Check the
operation of the recoil spring by lightly pulling
on the recoil spring tube to compress the
spring.
To install the bolt, cam pin, firing pin, and firing
pin pin insert the bolt into the front of the bolt
carrier.  Twist the bolt so that the extractor is on
the right side of the carrier and the cam pin
hole in the bolt lines up with the cam pin slot in
the bolt carrier.  Insert the cam pin into the hole
in the bolt, be sure that the tab on the cam pin
is pointing straight out the left side of the bolt
carrier.  Insert the firing pin into the back of the
bolt carrier, if it does not go in all the way the
cam pin or the bolt may not be inserted
correctly.  Push the bolt assembly into the
carrier as far as it will go and then insert thefiring pin pin into the bolt carrier from the left
side. DO NOT FORCE THE FIRING PIN PIN. If
it does not go in easily check that the firing pin
is installed correctly. Check the operation of the
bolt and firing pin to be sure that they move
freely. 
						

							Rifle assembly
With the rifle stock folded and the bipod
unlatched rest the rifle on its left side. Take the
bolt carrier assembly, pull the bolt out as far as
it will go and twist the recoil spring tube so that
the lock tab is at the top of the bolt carrier.
Insert the carrier from the rear of the receiver,
be sure not to twist the bolt tube or push in the
bolt as you insert it. Align the operating hole in
the carrier with the cut-out in the receiver and
insert the operating handle. Push the carrier up
slightly so that the operating handle aligns with
the slot for it and the recoil spring tube is
parallel with the barrel of the rifle.
WARNING: if the recoil spring tube is not
parallel with the barrel of the rifle the bolt
carrier assembly is not installed correctly.
Remove the carrier assembly and install it
again paying close attention to the align-
ment of the lock tab on the recoil spring
tube as you insert the carrier and also be
sure that the bolt itself is always in the
forward most position as you insert the
carrier assembly into the receiver.
Check that the forend lock ring is aligned
correctly and push the operating handle all the
way forward, be sure that the piston head lines
up and goes into the gas head.  Grip the recoil
spring tube, pull it forward and twist it ¼ turn so
that the locking tab on the recoil spring tube
goes into the receptacle on the left side of the
receiver. Pull the operating handle back and
forth to check that it moves freely, if it does not
take out the bolt carrier and check to make sureeverything is installed correctly and nothing is
damaged.  Close the bipod and unfold the
stock. Insert the assembly pin into the hole and
press it in until it is flush with the outside of the
stock.
Changing the safety operation direction:
The safety button on the SU-16 rifle can be
reversed so that the safety can be engaged by
either pressing on the right side, or the left side
of the safety button, depending on your
preferences.  You will need a few tools to flip
the safety button including a Philips head screw
driver, a small flat head screw driver or other
thin tool for prying, and a small paper clip.
Bend the paper clip out so that it has a small
hook on one end and a handle shape on the
other as shown in the figure below.
Unload your SU-16 rifle and cycle the operating
handle to be sure that there is no round in the
chamber.  Make sure the bolt is in the forward 
						

							position and the safety is engaged. Put the rifle
on one of its sides and loosen the four screws
on the sock that are closest to the muzzle end
of the rifle as shown in the figure. Do not loosen
screws that are screwed into the receiver. Flip
the rifle over and loosen the four screws that
were in the same position as the previous four
you just loosened.  Hold the rifle so that it is
upside down and resting on it’s top, you may
need to remove the sight and any other
accessories that are mounted to the picatinny
rail. Push your small screwdriver or prying toolinto the gap in the bottom rear of the trigger
guard so that there is enough of a gap to get
your paper clip tool in between the two stock
halves at the back of the base of the trigger
guard.  You may need another prying tool to
help enlarge the gap. Put your paper clip hook
into the gap you just pried open starting from
the butt end and move the hook towards the
trigger, you should be able to hook onto the
back of the trigger spring.  Lift up on your tool
to raise the trigger spring. While holding the
spring up push out the safety, flip it around, and
put it back.  Release the pressure on the trigger
spring and remove the paper clip hook. Check
to be sure that the safety moves back and forth
correctly. Remove the pry tool from the trigger
guard. Tighten all the screws that you loosened
on both sides of the stock. Check the operation
of the safety before loading the rifle.
SIGHT ADJUSTMENT
Sight adjustment on the SU-16 rifle depends on
the placement of the rear sight, if the sight is
placed farthest forward on the picatinny rail the
rifle will have a different sight radius than if the
sight is placed farthest rearward on the
picatinny rail. The main data below is given for 
						

							when the rear sight is placed on the farthest
rearward slot on the picatinny rail, the data in
parentheses is for when the rear sight is placed
on the farthest forward slot on the picatinny rail.
Use a coin or large screwdriver to adjust the
windage by the two screws on each side of the
front sight block. Before turning a screw
clockwise (in) the opposite must be backed out
the same amount. 1/4 of a turn changes the
point of impact 1.3(1.6”) at 100 yards or 1.3
m.o.a. (1.6 m.o.a.). One full turn is 5.2 m.o.a.
(6.4 m.o.a.) By turning the left screw clockwise
(in) the sight moves to the right and the point of
impact to the left.
Before tightening the screws, the post may be
pushed up or down to adjust elevation. .007
(.005”) will change the impact 1 m.o.a.
DO NOT OVER-TIGHTEN.MAINTENANCE
Your rifle is a precision instrument and to insure
reliable function, it is necessary to follow a
routine maintenance procedure. After firing your
rifle, be sure to unload it following the proce-
dure outlined in the section entitled “Unloading”
before any cleaning or maintenance procedure.
Routine cleaning, after every shooting
session:
Your rifle should be cleaned by brushing the
barrel bore and chamber with a good powder-
removing solvent and bore brush. Wipe the
areas clean with patches or a swab. Using a
small brush dipped in solvent, remove all
deposits from around the breech of the barrel,
and chamber, extractor and adjacent areas
which have been subjected to the action of
powder or primer residue. Remove any residue
on the frame with light brushing and a solvent.
After cleaning the entire gun, use a cloth to
apply a light coating of high quality gun oil to all
external surfaces and wipe clean.
Additional cleaning, after firing 500 rounds:
Remove the bolt carrier assembly and fully
disassemble it as stated in the disassembly
section of this manual. Thoroughly Clean with
solvent and a brush the piston head, piston pin,
piston rod, recoil spring, recoil spring tube, bolt,
cam pin, firing pin, and bolt carrier. Do not
clean the firing pin pin, solvents can damage
the O-ring used to hold it in place. Thoroughly
dry all parts. Apply a light coat of oil to the firing
pin, bolt, cam pin and the surfaces in the bolt 
						

							carrier where the bolt, cam pin, and firing pin
slide. Apply a light coat of oil on the piston rod
and assemble the bolt carrier assembly and
rifle as stated in the assembly part of this
manual.  Manually cycle the bolt back and forth
to check the function of the rifle. If any parts are
damaged or badly worn or the rifle does not
work correctly the rifle should not be fired and
should be returned to Kel-Tec for servicing
immediately.
LUBRICATION WARNING:
Firing a rifle with oil, grease, or any
other material even partially obstruct-
ing the bore may damage the rifle and
injure the shooter and those nearby.
Do not spray or apply lubricants
directly on ammunition. If the powder
charge of a cartridge is affected by the
lubricant, it may not be ignited, but the
energy from the primer may be suffi-
cient to push the bullet into the bore
where it may become lodged. Firing a
subsequent bullet into the obstructed
bore will damage the rifle and may
injure the shooter and bystanders. Use
lubricants properly. You are respon-
sible for the proper care and mainte-
nance of your firearm.
WARNING: It is not recommended that
you disassemble the stock of the SU-16
rifle; the hammer spring is constantly
under tension and can easily injure youor others. If the need arises to lubricate
the trigger assembly do so through the
access slot behind and in front of the
hammer.
