This is a
breakdown of all the parts that go into one complete semi automatic
Mini Uzi carbine. Notes about each part and differences versus
different versions of the Uzi will be noted.
The numbers below correspond
to the parts on the Mini Uzi carbine parts
diagram available on uzitalk.comhere.
All items marked with a "*"
indicate that this is a Mini Uzi only part
and not interchangable with the full size Uzi.
*1 - Barrel The semi auto barrel is 19"
from the factory. A ruling made it legal to reduce this size to 16"
which you might see with some Vector Arms produced Minis. The back end
is smaller for fitting inside the restriction ring of the semi autos. Full Auto / SBR / Pistol. This
has two angled ports on the front for compensation. The back end is
once again turned down for use in a semi auto gun with the restriction
ring but factory SMG barrels do not have this and in place, have a
thicker band halfway down the barrel for a second support so the barrel
doesnt move. See herefor
differences (photo credit Amphibian / C3junkie).
2 - Nut, Barrel retaining The threading on
these
are M26x1.5. The Micro Uzi and Uzi Pistol are M24x1.
3 - Catch, Barrel Retaining
4 - Spring, Barrel Catch
5 - Front Sight The Mini Uzis all used
Model B sights, except for the Vector Arms guns made from cut down
Group Industries Receivers which use Model A sights.
6 - Detent, Front Sight
7 - Spring, Detent Front Sight
*8 - Receiver Original IMI Mini Uzis had
receivers that are instantly identifiable by the secondary "ribs" on
the back end. The left side has one rib above the serial number area
and the other side has two. Guns made from cut down full size receivers
lack this or else can easily be spotted as a re-weld because the rib is
so hard to get perfect. The Mini had a variety of different stampings
on the back to identify them. All Action Arms guns have a stamping on
the underside indicating that they are AA guns and their place of
import and origin (PIC).
The Action Arms Mini Carbine has an MC before the serial to indicate
"Mini Carbine" (PIC). Mini Uzi carbine serial numbers
srarted at 1001.
The Mini Uzi Pistols that Vector Arms made were built on carbine
receivers but restamped to read Mini Uzi Pistol. They still retain the
MC prefix (PIC). The rare
"First Responder" carbine has a lot more stamping on it (PIC).As far as SMGs
go the original non-export IMI Mini was marked simply "Mini Uzi 9mm"
without any prefix in front of the serial (PIC). The standard
open-bolt Mini Uzi has an MU prefix (PIC). The closed-bolt Mini
had an MU-CB preifx (PIC).
Closed-bolt Minis were also made from semi carbines and can be
identified by stmaped out portions where the "carbine" and MC prefix
used to be (PIC).
*9 - Swivel, Sling
*10 - Handguard, Left
11 - Screw, Handguard A few aftermarket
companies use Allen bolts with an ugly bright gold/brass color to them
so be careful. Thread size 5-40.
*12 - Handguard, Right
13 - Nut, Handguard Bolt A few aftermarket
companies use Allen bolts with an ugly bright gold/brass color to them
so be careful.
14 - Catch, Cover
15 - Spring, Catch Cover
16 - Rear Sight The
Mini Uzis all used Model B sights, except for the Vector Arms guns made
from cut down Group Industries Receivers which use Model A sights.
17 - Spring, Washer, Rear Sight
18 - Pin, Drum Windage
19 - Drum, Windage
20 - Spring, Drum Windage
21 - Axis, Rear Sight
22 - Washer, Lock
*23 - Spring, Stock
*24 - Pin, Connecting
*25 - Folding Stock Assembly IMI produced two
variants of the folding stock. The newer design as a more flat back
that meets up with the rear of the receiver better. See pic here. The Mini Uzi stock is
sometimes used on the Micro Uzi but I have only seen one instance of
the Micro Uzi stock being used on a Mini and it looked rediculous.
26 - Screw, Cocking Knob
27 - Knob, Cocking
*28 - Plate, Slot Cover The semi auto has
modification warnings printed on it while the SMG version does not. You
may see closed bolt SMGs with the markings, but this is due to the fact
that closed bolts were often converted from previous semi auto guns.
*29 - Cover, Receiver The SMG version has
teeth and a ratcheting system to hold the bolt open upon firing the
last round. These can be used on semi auto guns by simply removing the
spring and ratchet piece. Once again, you may see
closed bolt SMGs with the non-ratcheting semi auto top cover, but this
is due to the fact that closed
bolts were often converted from previous semi auto guns. Top covers
that were made from cut down full size covers are instantly
identifiable by the recess over the ejection port. The real Mini top
covers are flat all the way from the front to back. See example here. 30 - Spring, Lug Cocking
31 - Lug, Cocking
*32 - Bolt The semi auto Mini Uzi bolt does
not feature the "feet" of a full auto bolt. The semi auto bolt and the
closed SMG bolt are very similar but their differences can be seen in
these pics: 1/2. Please refer to the
various sections on uzitalk.com, "Bolts", "Full
Auto Conversions" and "Full
Auto Conversions: Mini Uzi",
for more bolt specific
information. The Micro Uzi / Uzi Pistol bolt can be used in the Mini
Uzi but please notice the releif cut in the top in the Micro / Pistol
bolt seen here.
33 - Pin, Extractor
34 - Spring, Blocking Latch
*35 - Blocking Latch The Mini Uzi features a
slightly modified design of the regular Uzi's blocking latch. The Mini
is slightly smaller. The
difference can be seen here.
36 - Extractor The semi extractor differs
from the SMG extractor in that the semi is missing half of the "claw"
while the SMG version features a full lip to it. The SMG version can be
used in semi guns for a better extraction without modifications. The
differences are evident in this pic here

*37 - Striker The open bolt Mini Uzi SMG has
a bolt featuring a fixed firing pin.
*38 - Striker, Guide The open bolt Mini
Uzi SMG does not utilize a striker and essentially uses just a spring
rod as a recoil mechanism. See picture here
(photo credit uzitalk.com). For a pdf of dimensions of this striker,

*40 - Retaining Ring
*41 - Return Spring Assembly The open bolt Mini
Uzi SMG does not utilize a striker and essentially uses just a spring
rod as a recoil mechanism. See picture here

came
from the factory with the markings "FS" for "Fire" and "Safe". SMGs
would have come with the markings "ARS" which stands for "Automatic,
Repetition, Safe". "AFS" marked lowers are lowers that were once semi
lowers that had an "A" marked in. "RS" lowers would be lowers made from
"ARS" lowers to be semi and had the "A" welded over. Hebrew marked
lowers can be found but they most likely came from full size Uzi parts
kits. The first group (safe position) contains two letters -"NT".
It stands for the word Natzur. (Safe) The second group (semi position)
contains one letter - "B". It stands for the word Bodedet. (Single).
The third group (full auto) contains one letter - "A". It stands for
Atomatit. (Automatic). "DES" marked lowers are lowers that came off of
surplus German full size guns and are not original to the Mini. Vector
uses these lowers with their Minis now that they have run out of
original and Hebrew marked lowers. The "D" stands for "Dauerfeuer which
means "sustained fire", "E" stands for Einzelfuer, which means single
fire (semi auto), and "S" stands for Sicher, which means "safe".

49 - Pin, Pistol Grip The semi auto pin is
9mm diameter and the SMG is 8mm. The pin for the full size and Mini
Uzi is 1 3/4" long, while the Uzi Pistol is 1 5/8" long.

51 - Screw, Pistol Grip Cover Thread size 5-40.
52 - Button, Fire Selector
53 - Fire Selector
54 - Spring, Fire Selector
*55 - Sear The semi auto Mini Uzi sear is
unique in that it only has one sear pad. The factory marked these with
"MC" for "Mini Carbine". A full size carbine sear can be modified to
work in the Mini by grinding one of the sear pads flat. See these pics
for the differences: 1/2/3.
The semi auto barrel is 19"
from the factory. A ruling made it legal to reduce this size to 16"
which you might see with some Vector Arms produced Minis. The back end
is smaller for fitting inside the restriction ring of the semi autos.
