Minute Man Armor make armor that mounts into picatinny rails. Weird.

Jovian Thunder Bolt has more info.

On display at the DSEi 2009 defense expo was this cut down Benelli Super Nova pump action shotgun. Apparently it is popular with South American Law Enforcement.

In this short and stock-less configuration it is more like a pistol than it is a shotgun.

The information and photo were kindly provided by Lusaka who took the time to hunt for, and photograph, new and interesting arms on display at the expo. Thanks Lusaka, your efforts are appreciated. More cool guns from the show will be posted tomorrow.

Earlier this month Serbian police discovered a weapons cache hidden inside a buried oil tank. The weapons were found outside a village that was a former stronghold of an ethnic Albanian militia. It is quite impressive how much hardware and ammunition can be packed away in a relatively small space!

Investigative Judge with the Vranje District Court Staniša Mihajlović said that 100,000 bullets, a recoilless cannon, three mortars, six RPGs, three machine gun stands and 21 anti-tank mines were recovered from the tank.

Benelli, not wanting to miss out, has entered the lucrative black rifle market with Benelli MR1 Carbine, a 5.56mm gas piston operated rifle.

Benelli MR1 Carbine

The MR1 Carbine is the civilian version of the Beretta Rx4 Storm (which never took off). Benelli, a subsidiary of Beretta, designed the ARGO gas system used by the MR1/Rx4 and manufactured both the MR1 and the Rx4 Storm.

What differentiates the MR1 from other 5.56mm rifles is the gas system it uses. Originally the Auto-Regulating Gas System (ARGO) was designed for the Benelli M4 Super 90, better known by its US Military designation, the M1014 Joint Service Combat Shotgun. Benelli then adapted the system for their ARGO line of hunting rifles (branded the R1 in the United States). In 2005 the Beretta Rx4 Storm, a tactical version of the ARGO rifle, was introduced and marketed to law enforcement. As far as I know the Rx4 has never been available in a select fire variant but they decided to market it to civilians as the Benelli MR1.

Benelli ARGO EL

The ARGO gas system has an interesting short stroke piston design. Gas is trapped very close to the chamber. The high pressure gas ensures reliable cycling regardless of ammunition. This means that it can cycle any shotgun shells, regardless of the load. For a rifle it means the barrel can be very short and a suppressor could be fitted without any cycling issues. This gun is just asking to be converted into a Short Barreled Rifle!

The gas is then fed into an expansion chamber. The pressure in the chamber drives the piston assembly, which has dual rods. The high pressure is regulated by a release value. These diagrams should illustrate how the system works.

The receiver is made of aluminum, it is fully compatible with AR-15 magazines (including the 100 round drums) and, like all Benelli shotguns and rifles, the main spring is placed inside the butt stock - meaning a folding stock is not an option, although hopefully an M1014 folding stock will be made available.

MR1 Specifications:

Caliber: 5.56mm NATO / .223 Rem. Barrel: 16". Hard chrome lined. 1:9 twist. Rear Sights: Military-style Aperture Weight: 7.9 lbs.

The MSRP is $1299. I think they have priced it right. Although not cheap, and they can do better than the one five round magazine they ship with it, I doubt they could sell it much cheaper.

The ENDO Tactical Stock Adapter Glock Edition (TSA-G) is an adapter that allows any AR-15 / M16 compatible stock to be attached to a Glock pistol.

The adapter can be easily attached and removed in about 30 seconds. The benefits of such a system are numerous. Even with the stock attached it is small enough to be carried concealed under a jacket – unlike a rifle or carbine. The stock improves accuracy by steadying the pistol against the shoulder. This also helps soak up recoil allowing faster followup shots.

The downside of such a system, for civilians, is that any pistol it is used with must first be registered as a Short Barreled Rifle (SBR) with the BATFE. I am no expert, so don’t quote me, but my understanding is that carrying an SBR concealed, even without the stock, would not be allowed with a CCW permit in many, or all, states.

Another downside is the total cost of the weapon system. If we assume a new Glock 17 costs $500, then add $200 for the ATF stamp, $154.99 for the ENDO stock adapter and $60 for a Magpul MOE Carbine Stock, we get a total cost of 914.99! This is a lot more than a 9mm carbine such as the $400 Kel-Tec SUB-2000.

Cost aside, I really like the system. I don’t think there will be a shortage of enthusiasts who will be willing to pay. I expect ENDO will be marketing this heavily to Law Enforcement Organizations who carry Glock pistols.

The system is compatible with the G17, G22, G24, G31, G34, G35 and G18 (including the L, C and RTF versions).

On a side note, I am surprised by the attachment mechanism. A steel detent pin must be manually pushed through the pistol backstrap. Compared to the system used by the FAB Defense (Israel) stock which clips in, it takes longer to install and is more of a fiddle. I wonder if the clip system is patented.

Taser have just launched their new much-hyped X3 model. The X3 corrects a major flaw in the Taser system, something gun slingers realized at least 250 years ago, to wit, when dealing with people at close range a single shot is never enough. The X3 addresses this problem but giving the operator three shots.

Taser X3

This gives the X3 fifty percent greater ammunition capacity than a Derringer pistol, and just 82% less capacity than your plastic fantastic! Joking aside, the new multi shot capability is a technological breakthrough that significantly increases the utility of the device. It allow law enforcement officers to quickly follow up a missed shot or engage up to three targets simultaneously. This video demonstrates the multi target functionality:

Not only can it load three “Smart Cartridges”, but long range and short range cartridges can be mixed. The duel laser sight will automatically adjust the point of impact for the currently “chambered” cartridge, which I think is pretty nifty.

“Scary Arc Mode”

Another new feature is what I call the “Scary Arc Mode”. A button can be pushed which will cycle electrical arcs across the front of the device. While a superficial feature, it may persuade many a drunk to cooperate.

Other new features include safety, reliability and user interface improvements.

X3 Holstered

I think the X3 is one of those devices, like the iPhone, which can justify money being spent on an upgrade.

The Colt LE6940 Monolithic Advanced Law Enforcement Carbine, an upgrade of the 6920, have started popping up for sale. The rifle features Colt’s new monolithic upper receiver. This 1-piece receiver is machined from aluminum billet and includes a full length rail.

Photos from Gunbroker auction

The LE6940 has a 16.1″ free-floating, barrel, MaTech back-up rear iron sight and gas block mounted front sight. The rifles pictured are semi-automatic, but I am sure Colt will produce a variant with a rock-and-roll switch for law enforcement.

The Colt name does not come cheap, although neither do monolithic receivers, and if you can find one for sale it will probably cost you $2400-$2800. It does come with two 20 round magazines and a sling … if that makes the price easier to swallow.

CowTown Cop’s has posted a range report on his recent “Patrol Carbine” training. Well worth a read.

Our range was never intended to be used as a rifle range. It is 50 yards deep and the backstop is rated for pistol rounds. So we have to use this funny little blue bullet ammo that I despise. Its called SRTA which stands for short range training ammunition. Its a 3.6 grain plastic projectile that is traveling at 4350 fps at the muzzle. It requires you to use a straight blow back M2 training bolt in your AR. I
