Heckler & Koch Product Overview and New nomenclature

Heckler & Koch Product Overview and New nomenclature

http://ift.tt/2wuHzJl

Heckler & Koch, Germany, have been renaming their weapon systems. It’s been going on for a while and I’ve been trying to decipher this ever since I saw some of the new HK firearms at Enforce Tac 2017, Germany.

Could there be errors in my list? Yes, there’s no key from Heckler & Koch but I will be happy to correct them, missed conclusions etc. and look forward to input in the comments section below. There are for sure some digits missing that I don’t know (yet).

I have tried to add a lof ot pictures to make this more interesting, and there should be direct links to HK’s Homepage to most if not all firearms.

HK’s new 3 digit system can be found towards the bottom.

The Weapon Systems for Military and Law Enforcement is divided into the following areas.

PISTOLS – SUBMACHINE GUNS – ASSAULT RIFLES – MACHINE GUNS – PRECISION RIFLES – 40 MM SYSTEMS – GRENADE MACHINE GUN and TRAINING SYSTEMS.

We will skip the Pistols, Grenade Machine Gun and Training Systems this time and focus on the other firearms.

So, let’s begin:

SUBMACHINE GUNS

MP7 A1 and MP7 A2 in 4.6 MM X 30. Pictures from the HK catalog.

MP7 from EnforceTac 2017, my picture.

UMP

MP5, MP5 SD and MP5 K.

This Classic doesn’t need much if an introduction. (MP5 MLI pictured, from EnforceTac)

The Unicorn, with all modes of fire.

 

ASSAULT RIFLES

G36 A11, G36KA4, G36 KV3 and G36C.

HK416 A5 11″, HK416 A5 14.5″, HK416 A5 16.5″ and HK416 A5 20″.

MACHINE GUNS (Belt fed)

HK123 and HK123K (MG4)  in 5,56×45 NATO. Light Machine Gun.

HK123

Features: Safety catch may be applied in all bolt positions, Withstands barrel obstruction test to NATO-AC225/D14, tandards (soft core, dual core and steel core ammunition DM41, DM11, DM31, DM21), Gun mount interface, Full day and night combat capability, Sight rail as per NATO-STANAG 4694 to mount optical/optronic sights. Folding and telescopic buttstock options. Deployment-specific barrel lengths as quick-release barrel with carrying and barrel changing handle. Simple conversion to standard, infantry and vehicle mounted weapon. Almost similiar operation to HK 121.

HK123K (Short)

 

HK 121 (MG5 A2) in 7,62×51 NATO.

The HK121 in action.

Features: Safety catch may be applied in all bolt positions, Withstands barrel obstruction test to NATO-AC225/D14 standards (soft core and steel core ammunition DM111A1, DM151, DM21A2). MG3 gun mount interface. Full day and night combat capability, Sight rail as per NATO-STANAG 4694 to mount optical/optronic sights. Fixed, folding and telescopic buttstock options. Deployment-specific barrel lengths as quick-release barrel with carrying and barrel changing handle. Easy to convert to standard, infantry or vehicle mounted weapon without the need for tools (< 1 min). Three settings for the rate of fire. Maintenance-free bolt group buffer to stabilise the rate of fire and absorb the recoil. Belt feed with loadedstate indicator

Below: Some of my pictures from EnforceTac 2017 of the HK121, Universal Machine Gun.

Below: The letters “HK121” clearly visible on the cast iron receiver. It comes with a minimum service life of 50,000 rounds. Note the aluminum top with Picatinny rail. Don’t like the color matching? That’s what different surface finishing does to various materials.

The gas port on the HK121 can be adjusted without the need for tools, and gives approximately 640, 720 or 800 rounds/min.

 

PRECISION RIFLES

MSG90 A2 in 7.62 mm x 51 NATO.

HK241 in 7.62 mm x 51 NATO. DMR Rifle.

 

40 mm SYSTEMS

AG36/AG36 A1, GLM, HK169, HK269

An overview how the AG36, GLM and HK269s can be used on various rifles, including M4s, C7s and C8s.

Firearms using the 3 digit “new nomenclature” system:

As always, there are no rules without exceptions, so let’s begin with those:

The following rifles use another 3 digit system.

MR223, MR 308, MR556, MR762 (They are for the Civilian market).

HK416, HK417 (Assault Rifles).

And these “Classics” remain as well:

MP5, MP7, UMP, USC, G36, MSG90.

We wouldn’t like some of these to be renamed, would we?

 

Decryption of the new nomenclature (LEAF Firearms):

HK XXX

First Digit:

Not sure what this stands for. So far 1, 2, 3 and 4 have been used but I haven’t been able to figure out a system, if there is one? Some examples below:

1 HK121, HK123, HK169

2 HK233, HK237, HK241, HK269

3 HK337

4 HK433, HK437 (remember 416 and 417 are exceptions).

Second Digit:

1 Unknown or not used.

2 Machine Gun. Full Auto. Belt fed.

3 Assault Rifle. Full Auto.

4 Rifle. Semi-Automatic.

5 Unknown or not used

6 40 mm System

Third Digit: (Caliber)

1   7,62×51 NATO

2   Unknown or not used

3  5,56×45 NATO

4  Unknown or not used

5  Unknown or not used

6  Unknown or not used

7 .300 Blackout/Whisper

8  Unknown or not used

9 40 mm

 

Note: As the HK433 should arrive in 7,62×39 mm (Kalashnikov), one of those unknowns will sooner or later revel itself.

Funny enough, it is mentioned in the Heckler & Koch Press Release that the HK433 in 7,62 mm x 39 Kalashnikov would be called HK123. However that name is already taken, but only after that Press Release. And it’s the machine gun previously called MG4. Honestly, I think the names MG4, MG5 etc.are so much better than the 3 digit system and I’m not sure I’ll ever get used to it.

(It’s a bit when BMW decided to change the name of the BMW M3 to BMW M4. Because the M3 has 4 doors and the M4 has 2, well let’s say I’m still struggling getting it right.)

Sources:

HK433 Press Release HK433 01.03.2017

From the HK Homepage: HK123. That’s a machine gun in 5,56, not a HK433 variant.

 

In the HK 2017 catalog there is also an interesting chart showing the weight of various rounds and the potential combat load (rounds).
