LAGE Manufacturing, LLC. will soon be selling a .22 conversion kit that they have developed for the SWD Cobray M-10 and M-11 submachine guns.

This design uses your existing upper receiver and cocking knob with a drop-in barrel insert, bolt assembly, magazine adapter and modified UZI .22 LR magazines. The magazine inserts in the pistol grip mag' housing just like the original 9mm magazine.

LAGE currently manufacture a range of slow-fire upper receivers for M-11, M-10/9 (a version for the M-11A1 is in development). These uppers slow the rate of fire from 1100 RPM to 600 RPM, making the gun much more controllable.

These guns are well known for eating through ammunition with their very fast rate of fire. The cost of these uppers are around $760.

Many thanks to Jeff for the information, photo and links.

REMOV let me know that H&K have redesigned their version of the FN MAG 7.62mm machine gun (designated the L7A2 in the British Army). The new models have been completely redrawn from imperial to metric and also feature a lengthly picatinny rail (what self-respecting military firearm does not these days?).

There are two models, one being slightly shorter than the other.

Manroy Engineering have also redesigned their ME 7.62 GPMG, which is a mix of features from the L7A2 and MAG 58.

A big thank you to REMOV for the photos and information.

A leaked US Army report about the Battle of Wanat criticizes the reliability of the M4. On July 13, 2008 200 Taliban fighters attacked 48 US and 24 Afghan troops. Outnumbered 2.7 to 1 the M4 Carbines, which the troops were carrying, could not function reliably under the sustained fire they were required to put downrange. Fox News reports:

The platoon-sized unit of U.S. soldiers and about two dozen Afghan troops was shooting back with such intensity the barrels on their weapons turned white hot. The high rate of fire appears to have put a number of weapons out of commission, even though the guns are tested and built to operate in extreme conditions.

...

"My weapon was overheating,” McKaig said, according to Cubbison’s report. "I had shot about 12 magazines by this point already and it had only been about a half hour or so into the fight. I couldn’t charge my weapon and put another round in because it was too hot, so I got mad and threw my weapon down."

Snowflakes In Hell, via Michael Bane's blog, correctly points out that assault rifles are not machine guns:

No assault rifle is going to stand up to sustained automatic fire. They aren’t machine guns, and even a machine gun needs to have its barrel changed out if it’s been firing a lot.

The M4 has a very short 14.5" barrel and a relatively lightweight barrel profile. This allows the barrel to heat up much faster than a longer and heavier rifle or machine gun barrel. When the barrel of a closed-bolt gun gets very hot, cook-offs,when a round is ignited from the heat in the chamber, become a significant problem ... not to mention the fact that a soldier cannot fire a gun that is to hot to hold!

The Marines have been criticized by many for their plans to introduce an Infantry Automatic Rifle (IAR) into the mix of weapons issued to their troops. The IAR is not intended to replace the SAW but would be deployed alongside it, giving some riflemen a light weight weapon that can sustain automatic fire.

FN IAR. Switches from closed-bolt to open-bolt when automatically when barrel temperature increases.

The Army would do well to look into the concept.

At the end of last year the Marines announced they were awarding contracts for the development of IAR prototypes to Colt, H&K and FN. Since then I have heard nothing about the IAR.

There are discussions about the M4 failure at Wanat over at Snowflakes In Hell, via Michael Bane's blog and SaysUncle.

Many thanks to Jerry, Caedis, Lee and Lance for emailing me links about this story.

Colt have won a contract worth $126 million to manufacturer the FN designed M240B machine gun, the standard medium caliber machine gun of the Army and Marines.

Colt Defense, LLC., West Hartford, Conn., was awarded on Sept. 25, 2009 a $32,143,048 firm-fixed-price contract for M240B machine guns. Work is to be performed in Hartford, Conn., with an estimated completion date of Oct. 31, 2015. Bid solicitation was open to the Firms in the U.S. and Canada with two bids received. TACOM-RI, CCTA-AR-SA, Rock Island, Ill., is the contracting activity (W56HZV-09-D-0175).

Daniel Watters, an expert on military procurement, told me that the military have been trying to maintain, or expand, the small arms production industrial base by procuring from second sources.

Korean firm Dong In Optical specializes in red dot sights for machine guns, miniguns, grenade launchers and auto-cannons.

The Model DCL100 Red Dot Sight (below) is designed specifically for the FN Minimi / M249 and FN MAG / M240 light machine guns. It is seen here mounted on the Minimi Para, FN's short 13.7" barreled, collapsible stocked, machine gun.

I have an overwhelming desire to mount one of these on a Ruger 10/22

You saw it here first! I had no idea that Sig Sauer were making AR-15 / M16 rifles but my DSEi spy spotted this prototype SIG516 ¹ PDW at the DSEi 09 expo. It features a 7" barrel, putting it firmly in the PDW class, and chambers the 5.56mm NATO.

Markings indicate manufacture at the Sig Sauer plant in Exeter, NH, USA

I do not know if Sig plan on a civilian carbine version. If they did it would compete directly with their Sig 550 line of full length and short barreled rifles.

UPDATE: jcmiller points out that the lower receiver is semi-automatic. A production PDW would have to be fully automatic. Maybe Sig are thinking of civilian sales.

UPDATE:

The SIG516 Tactical Rifle line has three different models:

• SIG516 PDW : 7" barrel. A personal defense weapon (pictured above).
• SIG516 CQB : 10" barrel. A Colt M4 Commando equvelent.
• SIG516 BASELINE CARBINE : 14.5" barrel. A M4 Carbine equvelent.
• SIG516 Patrol. 16" barrel.
• SIG516 Tactical Marksman: 16" barrel A squad level sniper / designated marksmen rifle.
• SIG516 Precision Marksman: 20" barrel. Possibly a true sniper rifle, or designated marksmen rifle.

They are all piston operated and feature an adjustable gas regulator like the Ruger SR-556.

Upper receiver assemblies will be sold. Just before anyone gets their hopes up, while it is likely that Sig will sell civilians models, this has not been confirmed.

Big thank you to Lusaka for the information and photos.

The MP5SD is the integrally suppressed version of the famous MP5 submachine gun. This video, taken by the THOR Group, shows just how silent the gun is.

Unlike most videos on YouTube the sound on this video is very clear and you can distinctively hear that a lot of the noise is caused by the bolt itself, rather than the escaping gas.

One of the reasons I love my suppressed .22 bolt gun is that there is no noise from the action other than the firing pin smashing the case rim.

Thanks to Max for the link.

During the past few years India’s Armaments Research and Development Establishment (ARDE) have been developing an interesting Personal Defense Weapon (PDW) called the Modern Submachine Carbine (MSMC).

Modern Submachine Carbine

The firearm chambers a round developed in India called the 5.56×30mm. This round is sometimes referred to as the “5.56×30mm INSAS” after the first gun to chambered the round, the INSAS Carbine.

5.56×30mm MARS

Those of you who follow the industry closely may recall that Colt developed a round named the 5.56×30mm MARS during the 90’s as part of their now defunct Mini Assault Rifle project. I imagine the INSAS cartridge is very similar. The Colt patent describes the MARS cartridge:

The MARS cartridge is designed as part of the weapon system and exploits the high energy densities of modern ball powders. It for the first time uses magnum pistol type powders burned at rifle pressures to achieve high rifle velocities in a short rifle barrel. It uses a fast ball powder to achieve 2600 ft/sec with a 55 gr full metal jacket projectile in only an 11 inch barrel.

The MARS cartridge/rifle was able to achieve similar ballistics as a ultra-short barreled 5.56×45mm NATO rifle (I use the term rifle loosely, sub-carbine is more correct), but with less muzzle flash, noise and weight. The Indians went with the 5.56×30mm over the 5.56×45mm for these exact same reasons as Colt.

Out of a 11″ barrel, the MARS Rifle was able to push a 55 grain bullet at 2600 fps, generating 825 ft/lbs of muzzle energy. For comparison, according to Wikipedia, the original Colt Commando (11″ barreled sub-carbine) could push a bullet (presumably a 55 grain M193 Ball) at 2750 fps.

Colt M4 Commando (current model)

While the 5.56×30mm has advantages over a pistol cartridge such as the 9mm NATO, to wit, less weight and kevlar vest penetration, it has in my opinion one fatal flaw. 5.56mm bullets were never designed to operate at such low velocities. While 2650 fp/s may seem fast, that is at the muzzle, not 200 meters downrange where the target is situated.

A graph I generated. Numbers are estimates for illustration only.

Col. Martin L. Fackler, MD famously did a study which determined that a 5.56mm bullet (M193 and M855) would fragment only slightly ,or not at all, when hitting flesh below the speed of 2500 fps. Low fragmentation results in a .22″ sized hole in the target – less damaging that a .38″ (9mm) or .45″ hole.

Col. Martin L. Fackler, MD results

It will be interesting to see how this new sub-carbine and perform in real life, and what official nickname the cartridge is given. I think 5.56mm India or 5.56mm Short should are much better named than 5.56×30mm INSAS.

[ I have done my best to ensure there are no spoilers in this blog post, but read forth at your own risk and DON'T read the comments that are below the blog post. All pictures are from the trailers and promotional material, not the movie itself. ]

Two readers emailed me saying that many of the weapons I mentioned in my 5 Weapons that should’ve been in Transformers 2 post were used in new hit sci-fi movie District 9. I was considering seeing the movie, but after hearing this I decided I had to go. It was fantastic! Despite being a low budget production, they must have hired a very competent weapons consultant. The weapons used were appropriate for the task at hand and were used correctly, something few action, or even historical, movies do right.

Where can I buy this target?

There are three main human factions in the movie. The Multi-National United is organization styled after the UN. The Mercenaries (I can’t remember what they are called in the movie) are private military contractors styled after the likes of Blackwater (Xe). The Gangsters live among the aliens and are involved in the arms trade.

The movie is set in South Africa so it is no surprise that many of the weapons used in the movie are weapons produced by the South African defense industry.

Multi-National United (MNU)

Vektor CR-21 – This is the “white” gun used by the MNU. The 5.56 mm CR-21 is a bullpup version of the Vektor R4. The R4 is the South African licensed-built version of the Israeli Galil (an AK-47 derivative).

CR-21

R1 (FN FAL) – The R1 was the South African licensed-built FN FAL. In the movie it is used by airborne snipers.

R1 / FN FAL

Unknown Pump Action Shotgun – A pump action shotgun is used by a minor character. I could not identify it.

Mercenaries

Vektor R5 – This is the carbine version of the Vektor R4 rifle. The R5 has a 13.1″ barrel.

Vektor R5.

Colt M4 with M203 – Some troops appear to be using the M4 Carbine and M203 grenade launcher.

Colt M4/M203

FN Minimi – Better known as the M249 Squad Automatic Weapon (SAW).

FN Minimi

PMP Neopup PAW – I am pretty sure this awesome semi-automatic grenade launcher was used briefly.

Denel NTW-20 – This South African made 20mm rifle was used too good effect.

Unknown Machine Pistol – A machine pistol or submachine gun was used in one scene, but I could not identify it. UPDATE: Commenters point out that it was the BXP.

Unknown Pistol – I could not identify the pistols carried by the mercs. UPDATE: IMFDB says it was a Beretta 92FS.

Gangsters

AK-47 – Not introduction needed.

RPG-7 – Again, no introduction need. Used realistically in the film.

RPG-7

Milkor MGL – I was surprised to see the gangsters packing this. I only saw it in one scene.

M1911 pistol – I am pretty sure a 1911 clone is used by one of the gangsters.

Aliens

Unknown weaponry

Alien Assault Rifle

While watching the movie I tried to keep track of what guns they were using. I probably missed many and I had trouble identifying some. Please post a comment below if noticed any mistakes or omissions I have made or identify any of the unknown weapons listed.

Thanks to Cory and Raymond for their emails regarding the movie weapons.

UPDATE: More info at IMFDB (Spoiler alert).

CZ have introduced a new 9mm submachine gun called the Skorpion EVO III. Contrary to what the name suggests, it shares no heritage with the classic CZ Škorpion vz. 61 subgun.

CZ’s 2009 military weapon line up.

Since the 1993 split of Czechoslovakia into the Slovak Republic and the Czech Republic, the Slovakian arms industry has gone into decline and is now only a shadow of its former self. The fact that the Czech arms industry is doing well seems to be a source of irritation to the Slovak government.

The Skorpion EVO appears to be a cosmetic update to the Laugo LG 205 submachine gun that was designed by a Slovakian firm sometime in the last decade. They must have been unsuccessful in generating interest in the product and appear to have sold the design to CZ.

From the excellent site Small Arms Illustrated.

I know very little about the gun other than it is chambered in 9mm Luger / Parabellum, made of lightweight polymer and has all the picatinny rails you could want.

CZ are marketing it as a PDW (Personal Defense Weapon), although I cannot see any feature that distinguish it from any other 9mm submachine gun. You can see in the top image that they have given it the same stock and pistol grip as the new CZ S 805 rifle, which their marketing department are using as a selling point.

It will be interesting to see what becomes of this gun. At one point the designer (I have no idea who designed it, despite an hour and half of research) had it on display with a thumbhole stock and carbine length barrel. Personally I think it would have a great 9mm civilian carbine.

I know I said I was not going to blog for the next few days but I am very excited to finally see photos of the new Chinese made submachine gun I had heard about.

It looks a lot like what I would expect the child of a Sig 550 rifle and an H&K MP5 submachine gun would look like. I actually think it looks pretty good. Not much is known about this gun. It chambers 9mm less-lethal rubber bullet rounds (effective range of 10-80 meters) and 9mm Parabellum. The intended users are law enforcement.

It features a folding stock, H&K style diopter iron sight and quick detach red dot sight.

Grenade launcher attachment. Probably for less-lethal / crowd control ammunition.
Note MP5 style forward charging handle.

No, you did not mis-read the title. You though field stripping your AR-15 blindfolded was cool, well the Iranian army have got you beat

This is quite possibly the most ridiculous video I have ever watched online!

The Italian army adopted the Beretta BM59, basically an M1 Garand chambered for 7.62×51mm NATO capable of select fire. It was about as successful as all the other select fire battle rifles adopted around the world (not very). From Wikipedia:

After World War II, Italy adopted the US-designed M1 Garand rifle in .30-06 (7.62×63mm) and also manufactured it under license. This semi-automatic rifle proved itself well during WWII, but in the late 1950s it was considered outdated and obsolete. The Italian military wanted a new rifle chambered for the NATO-standard 7.62×51mm.

Beretta designed the BM59, which was essentially a rechambered M1 fitted with a removable 20-round magazine, folding bipod and flash suppressor/grenade launcher. The BM59 is capable of selective fire.

I came across this Class III, full auto, Beretta BM59 on Gunbroker (The auction has since close). Click to expand the photos:
