SAFETY SUMMARY
The following WARNINGS and CAUTIONS appear on the page referenced and are listed here
for emphasis.
Make certain fingers are outside of the trigger guard and
the weapon is pointed in a safe direction at all times. (Page 1-10)
Make certain the weapon is cleared. (Page 1-14, 3-7, 3-33)
ix
TM 09724A-10/1
Before starting an inspection, be sure to clear the weapon. Do not actuate
the trigger until the weapon has been cleared. Inspect the clamber to be
sure it is empty and that there are no obstructions in the barrel. (Page 2-3)
Never try to force a cartridge to chamber. If the bolt does not fully
close, release the magazine, clear the weapon, and check for obstructions,
but do not attempt to fire. Serious injury could result. (Page 2-11)
x
TM 09724A-10/1
After the weapon is unloaded, and with the charging handle to the rear,
always physically check the chamber for ammunition to preclude injury
from an accidental discharge. (Page 2-13)
The battery used in the Tactical Light System is a lithium battery. Battery can
explode or cause burns if disassembled, shorted, recharged or exposed to fire or
high temperatures. Turn old battery in to the Unit Armory. (Page 2-27)
xi
TM 09724A-10/1
When disassembling spring loaded parts, point components away
from face/eyes to avoid possible injury if parts fly free. (Page 3-9)
When disassembling magazine, point the bottom of the magazine away from face.
(Page 3-15)
xii
TM 09724A-10/1
Double hearing protection should be worn when firing since harmful
levels of noise are generated. (Page 3-34)
Do not fire corroded or dented cartridges with loose bullets,
or any other defective rounds detected by visual inspection. (Page 4-2)
xiii
TM 09724A-10/1
Do not leave cartridges in the magazine for extended periods of time
since this will cause the spring to lose tension and may cause a
malfunction. (Page 2-13)
The battery used in the Tactical Light System is very powerful. Be sure that the
switch is not touching anything when the weapon is stored. If the lamp is turned
on while in a case or other container, the lamp can overheat and damage the
tactical light or surrounding materials. (Page 2-29)
xiv
TM 09724A-10/1
Use only authorized lubrication. Do not mix lubrication. (Page 3-1)
Further disassembly of trigger mechanism should only be performed
by ordnance personnel. (Page 3-12)
xv
TM 09724A-10/1
Always clean the weapon from the chamber end. Never reverse the direction of
the bore brush inside the bore. This damages the bore brush and could damage
the bore as well. (Page 3-21)
Do NOT allow fluid to enter the Tactical Light Assembly.
This may damage components and cause light failure. (Page 3-24)

Section II. EQUIPMENT DESCRIPTION
1-5. GENERAL DESCRIPTION. The MP5N Submachine Gun is an automatic small arms
weapon. It permits either single shots or full-automatic tire to be fired from all positions. The
MP5N is recoil-operated, with fixed barrel and delayed roller-locked bolt system. The high
accuracy of the MP5N results from the fact that the submachine gun tires from the closed bolt
position, in conjunction with the recoil operated delayed roller locked bolt system. The delayed
1-2
TM 09724A-10/1
roller locked bolt system also allows the MP5N to be controlled more easily when firing fullautomatic fire. MP5N components are listed in Appendix B.
a. The left side of the MP5N, Figure 1-1, reveals flash suppressor (1), front sight (2),
charging handle (3), serial number location (4), sling connection (5), locking catch (6). magazine
catch (7), and hand guard (8).
b. The right side of the MP5N, Figure 1-2, reveals rear sight (1), pressure switch for
tactical light (2), tactical light (3), magazine (4), magazine release button (5). magazine release
lever (6), trigger (7), selector lever (8), and retractable butt stock (9).

1-7. DESCRIPTION OF MAJOR COMPONENTS. (Refer to Figure 1-3)
(1) BARREL AND RECEIVER ASSEMBLY. The receiver connects the barrel, flash
suppressor, charging handle, and front and rear sights. In addition, all assemblies are either
contained in the receiver or attached to it. The barrel is press-fitted into the barrel extension and
fixed in place by means of pins.
(2) BOLT CARRIER ASSEMBLY. The bolt carrier assembly is housed and guided in the
receiver; in conjunction with the recoil spring, it feeds and fires the cartridge, extracts and ejects
the empty cartridge ease after firing, and cocks the hammer.
(3) RETRACTABLE BUTTSTOCK ASSEMBLY. The two guide rails on either side of the
buttstock are guided in grooves on the receiver. They are secured by a locking catch in both the
retracted and extended positions. A sling holder is attached to the back plate.
(4) PISTOL GRIP AND TRIGGER MECHANISM ASSEMBLY. The pistol grip is hinged to
the receiver and can be swung down and removed from it; it contains the trigger mechanism,
with components of the trigger and safety, The safety axle connects the trigger mechanism to
the pistol grip. The selector lever is ambidextrous.
1-9
TM 09724A-10/1
(5) MAGAZINE ASSEMBLY. The magazine is attached to the receiver through the magazine
well and is held in place by the magazine catch. The forward motion of the bolt carrier
assembly strips the cartridge from the magazine and feeds it into the chamber.
(6) HANDGUARD ASSEMBLY AND TACTICAL LIGHT. The tactical light combines
housing. lamp. switch, batteries and handguard into a single unit. The handguard encircles the
barrel from below. It is attached to the weapon by a locking pin.

OPERATING INSTRUCTIONS
Section I. PREVENTIVE MAINTENANCE CHECKS AND SERVICES
2-1. PREVENTIVE MAINTENANCE
a. Before Firing. Always clean and inspect your weapon prior to firing. Firing a
weapon with a dirty bore or chamber may cause a weapon failure during a critical moment,
Apply a light coat of Cleaner, Lubricant and Preservative (CLP) on all moving parts,
b. After Firing. The MP5N must be cleaned after it haa been fired because firing
produces deposits of primer fouling. powder ashes, carbon and metal fouling. Although modem
ammunition has a non-corrosive primer which makes cleaning easier, the primer still leaves a
deposit which may collect moisture and promote rust if not removed. The weapon must be
cleaned within a reasonable interval, a matter of hours after firing. Repeated firing will not
injure the weapon if it were properly cleaned prior to the first round. After firing the weapon,
clean for three consecutive days using the items listed in Appendix B. Following the three
consecutive days of cleaning, check the weapon the next several days for fouling by running a
clean swab through the bore.
2-1
TM 09724A-10/1
(1) Clean the bore and chamber. Thoroughly clean the bolt and trigger
mechanism, removing all carbon deposits. Repeat this cleaning for three consecutive days, or
until there is no longer any evidence of fouling in the bore.
(2) After the fourth cleaning following firing, and if no additional tiring is
anticipated within the next 24 hours. use clean, dry swabs to thoroughly dry bore and chamber.
Then, using clean swabs which have been dipped in CLP and the excess wrung out, apply a light
film to the bore and chamber.
(3) Remove the bolt head from the bolt carrier assembly and thoroughly
clean its interior and exterior. Remove all brass fouling and powder residue from the face of the
bolt. being especially alert to fouling on the bolt face and the firing pin hole.
(4) Thoroughly dry all other components and apply a light coating of CLP
or another approved lubricant.
c. Daily Service. As part of daily service, inspect the bore and chamber, and clean
component parts of the weapon. Wipe entire weapon thoroughly, dry, and relubricate.
2-2
TM 09724A-10/1
d. Extended Periods. For periods greater than two weeks, renew the oil film in the
bore and chamber every four days. If the weapon is not being fired, apply a medium coat of
CLP to provide extra lubrication and corrosion protection.
2-2. INSPECTING THE WEAPON. Inspect all assemblies for missing, broken, or loose
parts. Inspect parts for cracks, dents, burrs, excessive wear, rust, or corrosion. Make sure all
items are cleaned and lubricated. Repair or replace defective pans, or evacuate the weapon to
intermediate maintenance if repair or replacement is not authorized at organizational
maintenance. Field strip the weapon (pars 1-9, page 1-14) and inspect as follows:
Before starting an inspection, be sure to clear the weapon. Do not
actuate the trigger until the weapon has been cleared. Inspect the
chamber to be sure it is empty and that there are no obstructions in the
barrel.

Section II. OPERATIONS
2-3. LOADING THE WEAPON.
a. Magzine. Using the appropriate ammunition, load the magazine. Hold the
magazine in one hand: with the other hand, place the cartridge on the magazine follower, Figure
2-1, and with slight pressure with the thumb, push the cartridge under the magazine lip. Ensure
that all cartridges are pushed all the way to the rear of the magazine.
b. MP5N. With the selector lever on SAFE and prior to inserting the magazine,
grasp the charging handle and dry-cycle the weapon several times (work the bolt all the way
back and forth). This will determine if the bolt carrier assembly is functioning properly.
(1) Insert the magazine into the magazine well. Tug on the magazine to
ensure it is locked in place. The magazine should lock with an audible click as it engages the
magazine catch (1) Figure 2-2.
(2) With the selector lever on SAFE and the muzzle pointed in a safe
direction, pull the charging handle 10 the rear and allow it to snap forward. The weapon loads
and locks a cartridge into the chamber for firing.

TM 09724A-10/1
Never try to force a cartridge to chamber. If the bolt does not fully
close, release the magazine, clear the weapon, and checks for
obstructions, but do not attempt to tire. Serious injury could result.
d. Because the weapon has a substantial recoil, the shooter must be positioned
squarely behind the weapon, otherwise. accuracy may be diminished, injury or discomfort may
result, or the action may fail to cycle correctly.
2-11
TM 09724A-10/1
e. With the selector lever turned to either the SINGLE or FULL AUTO
(full-automatic) position, (Figure 1-4 on page 1-11), the MP5N may now be fired. The weapon
will fire one round for each squeeze of the trigger when the selector lever is in the SINGLE fire
mode, or fire continuously with one pull of the trigger when the selector lever is in the FULL
AUTO tire mode. or until the magazine and chamber are empty.
f. If a cartridge or round jams in the chamber and can not be removed by immediate
action, evacuate the weapon to the next higher echelon of maintenance.
2-4. UNLOADING THE WEAPON
a. MP5N. Rotate the selector lever to SAFE (Figure 1-4 on page 1-11). Push the
magazine release lever forward or depress the magazine release button to remove the magazine
(Figure 1-5 on page 1-12). Engage the charging handle in the recess, which will eject any
cartridge still chambered. The bolt does NOT automatically remain to the rear when the weapon
or magazine is empty. After the MP5N is unloaded, and with the charging handle to the rear,
look into the chamber and feel with a finger to make certain the breech area and chamber are
empty.
2-12
TM 09724A-10/1
b. Magazine. To unload the magazine, hold it in the left hand with the bullet end of
the cartridge pointing towards your right band. With the right thumb, push the cartridge out of
the magazine and into the right palm.
After the weapon is unloaded, and with the charging handle to the
rear, always physically check the chamber for ammunition to preclude
injury from an accidental discharge.
Do not leave cartridges in the magazine for extended periods of time
since this will cause the spring to lose tension and may cause a
malfunction.
2-13
TM 09724A-10/1
2-5. CYCLE OF OPERATION. The cycle of operation for the MP5N is broken down into
eight basic steps, and more than one step may occur at the same time.
a. Feeding. The force of the recoil spring pushes the bolt forward, toward the barrel
extension, stripping a cartridge from the magazine and loading it into the chamber (by hand
using the charging handle when first loading and then by semi-automatic action thereafter).
b. Chambering. The bolt forces the round folly into the firing chamber, and the
extractor snaps over the case rim. Blockages (dirt or debris) can prevent full cambering, as can
dirty, bent, dented, or otherwise faulty ammunition.
c. Locking. The weapon relies on a delayed roller-locked bolt system. During
cambering the bolt head (1), Figure 2-3, enters the barrel extension (2). The angled shoulders
of the locking piece forces the locking rollers (3) into the contours of the barrel extension, to
lock the weapon. The firing pin (4), is now in positioned behind the cartridge for firing.
2-14
TM 09724A-10/1
Figure 2-3. Bolt In The Locked Position
2-15
TM 09724A-10/1
d. Firing. When the trigger pivots on its axle, the back of the sear (1), Figure 2-4.
rises, causing the front of the sear to lower. This action removes the sear from the notch in the
hammer (2), causing the hammer to pivot on its axle. As a result of spring tension, the hammer
is allowed to strike the fining pin (3) and ignite the primer of the cartridge,
e. Unlocking. When the cartridge is fired, gas pressure exerts a thrust on the bolt
head face. The bolt head carrier (1), Figure 2-5, carries the bolt to the rear to unseat and
compress the locking rollers. The balanced angular ratio of the locking piece (2), and the
locking rollers causes a delayed recoil movement of the bolt head, thus guaranteeing that the bolt
keeps the barrel locked until the bullet has left the muzzle. The bolt head earner continues
rearward until it contacts the fact of the hammer, forcing the hammer to cock and the recoil
spring to be compressed.

f. Extraction. With the extractor (1). Figure 2-6, crimped around the extracting
groove on the cartridge case. the rearward movement of the bolt head carrier allows the empty
cartridge to be removed from the barrel extension during the recoil and compression of the
locking rollers (2).
g. Ejection. As soon as the fired case has been extracted and has cleared the rear of
the barrel extension, it is expelled from the weapon by the ejector (1). Figure 2-7, which is
located within the trigger mechanism.
h. Cocking. As the bolt recoils to the rear, it rides the hammer back and down
causing the hammer to engage the sear (1), Figure 2-4.

sight with a tritium dot and an adjustable diopter-rotary rear sight with four different aperture
openings.
a. Elevation Adjustment
(1) Insert elevation adjustment tool (1), Figure 2-8, into the rear sight
cylinder (2), in such a manner that the prongs of the tool engage the two detents in the cylinder,
which contain the catch bolts. Press phillips-head screwdriver downward into the adjustment
tool and hold firmly.
(2) Rotate rear sight cylinder manually in the desired direction (rotating
clockwise lowers the strike of the round 1.4 cm {0.55 inches) per click at a range of 25 meters,
rotating counter-clockwise raises it correspondingly).
(3) After performing the correction, withdraw phillips-head screwdriver
and remove elevation adjustment tool. The catch bolts will then re-engage in the splines.
(4) After performing the elevation adjustment, re-set the rear sight cylinder
to the desired aperture.

3-8. CLEANING THE WEAPON. Cleaning is a vital part of the maintenance procedure, and
should always begin with an inspection of the weapon system. Inspection and disassembly are
discussed in this manual in Chapter 2, Section 1 and in Chapter 3, Section 3, respectively.
a. General. The MP5N should be cleaned as soon as possible after firing, and each
time it is exposed to field conditions, using the items listed in Appendix B. Under extreme
conditions of combat or climate, it may be necessary to clean and lubricate the weapon more
than once a day. Under ideal conditions, when not being used and if stored in a clean, dry
location, it may only be necessary to inspect, clean, and lubricate once every 90 days. Begin by
field stripping the weapon (para 1-9 on page 1-14).
b. Barrel and Receiver Assembly
(1) Apply a liberal amount of CLP to a 9 mm bore brush and vigorously
scrub the bore. Always insert the bore brush from the chamber end and push it all the way
through the barrel without stopping. Do not allow the brush to stop in the bore, as it may
become stuck. Repeat this in/out procedures for a minimum of three complete trips and allow
the CLP to sit a few minutes.
3-20
TM 09724A-10/1
Always clean the weapon from the chamber end. Never reverse the direction of
Use bore brush inside the bore. This damages the bore brush and could damage
the bore as well.
(2) Do the same thing to the chamber. Clean the chamber face and barrel
extension with a chamber face brush rotated several times in a clockwise direction.
(3) Apply a few drops of CLP to a toothbrush and scrub the area around
the barrel extension and along the length of the receiver rails to break-up the carbon fouling.
(4) Using clean, dry swabs, swab the bore (including chamber) until the
swabs finally come out clean and dry. (Since the bore "sweats out" fouling and residue, it should
be cleaned for at least three consecutive days after tiring, or until there is no further evidence of
this sweating.
3-21
TM 09724A-10/1
c. Bolt Carrier Assembly
(1) Scrub all parts of the bolt group with a toothbrush and CLP where
carbon is visible, especially around the extractor and the bolt rollers. Insure that the rollers are
clean and are free to easily move in and out.
(2) There is no functional need to remove the extractor for cleaning.
Removal may damage the extractor spring.
(3) Clean the rest of the bolt with rags and a general purpose brush.
d. Retractable Buttstock Assembly
(1) Remove any foreign debris from the exterior using rags and a
toothbrush.

CHAPTER 4
AMMUNITION
Section I. AMMUNITION INSTRUCTIONS
4-1. AUTHORIZED AMMUNITION This Chapter discusses the ammunition available for
use with the MP5N. The MP5N submachine gun was designed to use ammunition designed to
NATO specifications. When dealing with the ammunition for this weapon, several do's and
don’t’s must be considered:
a. Do use:
(1) 9 x 19 mm NATO, Parabellum or Luger ammunition of recent
manufacture.
(2) Clean burning ammunition.
(3) Non-corrosive ammunition.
4-1
TM 09724A-10/1
(4) Hollow point, silver-tip, soft point, ball, etc.
(5) Subsonic ammunition.
Do not fire corroded or dinted cartridges with loose bullets, or any
other defective rounds detected by visual inspection.
b. Do not use:
(1) Reloads or re-manufactured ammunition.
(2) Aluminum cased ammunition.
4-2
TM 09724A-10/1
(3) Corrosive ammunition (primer and/or propellant).
(4) Any ammunition that exceeds NATO pressure limits (maximum
38,000 p.s. i).
section II. AMMUNITION LOGISTICS
4-2. CARE, HANDLING, AND STORAGE. For information on the care, handling, and
storage of all 9 mm ammunition, refer 10 TM 9-1300-200, or MCO 8020.1.
a. Protect ammunition from mud, sand, and water. If the ammunition gets wet or
dirty. wipe it off at once with a clean dry cloth. Wipe off light corrosion as soon as it is
discovered. Turn-in heavily corroded cartridges
4-3
TM 09724A-10/1
b. Do not expose ammunition to the direct rays of the sun. If the powder is hot,
excessive pressure may develop when the weapon is fired.
c. Do not oil or grease ammunition. Dust and other abrasive that collect on greasy
ammunition may cause damage to the operating parts of the weapon. Oiled cartridges produce
excessive chamber pressure.
