Introducing the RagnarokSD for Suppressed Pistols

Glock 19 with Trijicon Suppressor sights and Gemtech Tundra

We here at T.Rex Arms are happy to announce the RagnarokSD, a new OWB holster for the easy carry and rapid deployment of suppressed handguns. The SD supports a wide variety of weapons and suppressors, and its unique shape allows a user to draw and fire the weapon in the same short vertical motion common to standard OWB holsters.

The Ragnarok SD is precision-formed from heavy-duty .125″ Kydex, and is further strengthened by structural ribs that provide a more secure grip on the Surefire X300 series weapon light. The suppressor is braced by vented Kydex arms, which can be modified by the user to support the outside diameter of any can.

While this is a passive-retention holster, with no hood, strap, or button to release the firearm, the retention is fully adjustable. The holster requires the use of an X300U or X300V weapon light, but is available for all Glocks and various Sig, M&P, HK, CZ, FN, and XD suppressor hosts.

The back of the holster features the company’s Ragnarok mounting system, which is compatible with accessories from Safariland, Bladetech, Blackhawk, G-Code, S&S Precision, and others, allowing it be run with countless quick-detach systems, paddles, and offset mounts.

Glock 19 with Trijicon Suppressor sights and Gemtech Tundra

Like all Ragnarok holsters, the SD is modular, tough, and fast. Regardless of the configuration used, the weapon can always be deployed with a drawstroke of less than 6″. It is can be ordered now in Black, Ranger Green, Wolverine Brown, Multicam Original, and Multicam Black.

Ambushed by Reality

Urban millennials Jay Austin and Lauren Geoghegan, both in their late 20s, came to the popular opinion that they were wasting their lives working. Austin wrote on his blog about his intention to quit his job and “to charge headlong into indulgence…”

Persuading his girlfriend to go cycling with him in exotic overseas locations would be one indulgence; another was clinging to the politically correct notion that evil does not exist in the hearts of men. These two indulgences do not make a wise combination in the real world.  Especially in a 96.7% Islamic nation[1] like Tajikistan, where the couple came face-to-face with the opinions of Muhammad, who commanded all Muslims of all times and places to “Seize [the disbelievers] and kill them wherever you overtake them.” (Quran 4:89 – 91)

As Jay and Lauren were cycling on a dirt Tajik highway with some other Western cyclists, they were overtaken by a van of devout Muslims.  The Muslims knew their religious duty, and so the van passed the American cyclists, turned around, and smashed at high speed into the group, knocking Jay and Lauren into the ditch. The devout worshippers then descended on Jay and Lauren with knives. The State Department won’t release details of what happened next, but here’s what we know:

Jay, Lauren and two other cyclists are dead from lethal knife wounds, ISIS took credit for another Islamic victory over the disbelievers, and the murderers celebrated publicly on the world wide web.

21st century reality can be observed, evaluated and measured in a number of ways.  Let’s do some simple math.  Since the day Jay and Lauren were old enough to read simple statistics, there have been over 33,692 successful (meaning lethal) attacks by theologically-motivated Muslims against those they determined needed to be humiliated and punished with death.[2]  Jay and Lauren have been added to that numerical account of reality.  As we and others look at these brutal facts, how do we interpret the ideological force behind these murders?  How do we view this recent incident in Tajikistan?  Was it evil, or was it just some multicultural guys charging into the indulgence of a customary local sport?

What if evil is not a make-believe concept but a force of informed, deliberate destruction and slaughter?  The Muslims in the van clearly understood the commands of the Quran, and the commands of the Caliph.  In a 2014 internet message, Abu Muhammad al-Adnani, the chief spokesman for the Islamic State, reminded Muslims worldwide, “If you are not able to find an IED or a bullet, then single out the disbelieving American, Frenchman, or any of their allies. Smash his head with a rock, or slaughter him with a knife, or run him over with your car, or throw him down from a high place, or choke him.”[3]

Writes John Hayward, “A pro-Islamic State media operation called the Nashir News Agency published a poster…depicting an SUV driving across a mountain of skulls beneath the caption, ‘“Run Over Them Without Mercy.”’

“This is not the first exhortation to vehicular jihad published by the Nashir News Agency.  A few weeks ago, they published a message in both English and Arabic that said, ‘“Kill the civilians of the Crusaders, run over them by vehicles, gain benefit from Ramadan.”’

“This earlier poster was a much less polished bit of propaganda, accompanied only by clip art of a handgun, knife, and truck. The pictures were helpfully labeled “Handgun,” “Knife,” and “Truck” for the benefit of less subtle jihadi minds.”[4]

If less subtle jihadi minds can understand evil instructions and practice them, why can’t average American millennials see the reality of this false theology and call it evil?

On his blog, Jay Austin invoked political correctness to justify his own superstitious theology of living, traveling and indulging himself. “Evil,” Austin wrote, “is a make-believe concept we’ve invented to deal with the complexities of fellow humans holding values and beliefs and perspectives different than our own—it’s easier to dismiss an opinion as abhorrent than strive to understand it.”

But what if an opinion is abhorrent, and we understand it perfectly?  Should we not abhor it as destructive evil?  We could dismiss 33,692 crimes as accidents,[5] and live in blissful denial of reality…or we could tell the truth about evil and resist it with equal or greater force.  This is the present conflict millennials need to settle in their minds, or destructive evil will ambush them continually until they face the cold, hard truth.  Evil is not a make-believe concept.  Millennials need to stop supporting the agenda of the left which opposes the fighting of evil and works to disarm those who might understand evil and resist it.  Evil does exist.  The sooner millennials understand this, the sooner they can join the fight against real evil.  The sooner they understand that the childish denial of truth contributes to evil, sorrow, suffering and pain, the quicker evil can be overcome with good.

Dr. Jordan Peterson got to the heart of the matter when he told a bunch of college kids, “Maybe it’s not the world that’s at fault,” he said.  “Maybe it’s you. You’ve failed to make the mark. You’ve missed the target. You’ve fallen short of the glory of God. You’ve sinned. And all of that is your contribution to the insufficiency and evil of the world.”

Is it possible for left-leaning millennials to come to their senses?  Of course.  Thousands are, all across the West.  In the 20th century, the American leftist James Burnham rejected political correctness, and learned to describe evil for what it was.  Way back in the 1960s he could see where fantasy and wishful thinking about ethics were headed.

“Modern liberalism,” he wrote in Suicide of the West, “does not offer ordinary men compelling motives for personal suffering, sacrifice, and death. There is no tragic dimension in its picture of the good life. Men become willing to endure, sacrifice, and die for God, for family, king, honor, country, from a sense of absolute duty or an exalted vision of the meaning of history…. And it is precisely these ideas and institutions that liberalism has criticized, attacked, and in part overthrown as superstitious, archaic, reactionary, and irrational.”

It’s time for the West to call political correctness “superstitious, archaic, reactionary, and irrational,” and aggressively replace this false faith with truth.  Or we will continually be ambushed by a determined, confident, muscular and relentless evil.

New YouTube video about 3D Printed Guns

So, the furor over 3D printed guns continues! Last week I was in Washington DC, and took the opportunity to shoot a short video about what the proposed bans on tools and information would mean. Bear in mind that this is not just a 2nd Amendment issue; to control information, publishing, and speech, the U.S. Government would need to infringe on virtually every foundational principle of our Constitution.

New Attack on Defense Distributed and 3D-Printed Guns

It’s going to be an interesting week in the Gun Control debate! There is of course, no massive gun violence disaster at the moment (unless you count crime rates in cities with bad gun laws), but there are some upcoming midterm elections… which explains why earlier this week, Democratic senators and Attorney Generals lashed out against an upcoming “Ghost Guns” apocalypse that could only be averted by new legislation, which could only be brought by new legislators, who are currently running for office.

That being said, there was a gun-related legal decision last month that kicked all of this off, and it does bear talking about. A quick recap: In 2013, the State Department demanded that Cody Wilson shut down, a collection of downloadable 3D firearm files, claiming that sharing digital blueprints was a violation of ITAR’s weapon export controls. Wilson took down the files, and then sued the State Department, arguing that the order violated his First, Second, and Fifth Amendment rights.

To fund his lawsuit, Cody Wilson’s company Defense Distributed has been selling miniature CNC mills programmed to finish out 80% lowers for AR-15s, 1911s, and Glocks. After five years of legal back-and-forth, the US State Department finally settled the suit, paid back 10% of Wilson’s legal fees, and admitted that digital firearm blueprints could legally be published online.

This is just common sense; apart from his 3D-printable Liberator pistol, the 3D files Wilson was sharing online were mostly things like AR-15 and 1911 measurements and CAD drawings, information that has been publicly available and globally published for decades. It’s preposterous so say that information in one form (physical) is legal, while the same information in an other form (digital) is illegal.

However, this isn’t really new territory; the US government has been trying to control dissemination of computer code for decades as well. Major cases involved sanctions on the inventors of early encryption algorithms, and attempts to outlaw digital movies files on hard drives, while legalizing digital movie files on DVDs. Nevertheless, US legal precedent tends to favor the idea that computer code is free speech.

Which is why Cody Wilson’s new opponents aren’t attacking him on those grounds. Shortly after the State Department’s quiet retreat, the (Democratic) Attorney Generals of eight states (Washington, Oregon, Massachusetts, Connecticut, New Jersey, New York, Pennsylvania,  Maryland, and of course, the District of Columbia) have launched a new lawsuit to shut Cody Wilson down again, this time on the basis of public safety, horror stories about potential terrorism, and because it was Trump who made the State Dep’t give free gun blueprints away.

If you read through the complaints from the various (Democratic) AGs and legislators, you won’t find any mentions of free speech, CNC machines, or the constitution. All they can talk about is Trump, 3D printers, magical machine guns showing up in “any public place.” At a press conference last week, Senator Richard Blumenthal (D-Connecticut) warned that “these Ghost Guns are the new wave of American gun violence… They are undetectable, untraceable; forget about the TSA guarding the plane that you board!”

As he spoke, a somber Sen. Edward Markey (D-Massachusetts) slowly lifted a giant poster depicting two AR-15’s with (possibly) polymer lower receivers, but obviously equipped with metal upper receivers, metal bolts, metal barrels, metal rails, metal sights, metal optics, and presumably metal internal parts and loaded with metal ammunition. Reporters covering this issue have been equally clueless as the technology they are discussing.

Nevertheless, I predict that this lawsuit, ostensibly aimed at Cody Wilson but repeatedly naming Donald Trump, won’t last long after the midterms. If it can scare a few voters out to the polls it will have done its job. Unfortunately, the demonizing of guns, 3D printers, computer code, and free speech will not end any time soon. We need to continue to defend all the tools that will allow us to defend liberty.

Check back on the blog, and we’ll be talking from about this issue, especially as it relates to 3D printing, gun manufacturing, and the ways that new technologies are affecting these issues.

Suppressed USP 9

Looks a lot like a video game doesn’t it? HK USPs have definitely been glorified in a number of stealth-shooter video games from the late 90s and early 2000s. I’m currently trying out this particular setup and will probably produce a YouTube video on it in the near future.

USP 9 with Surefire Ryder 9 in the short configuration, GGG rail adapter, Surefire X300U, DG switch. I’m running the stock DA/SA trigger. Probably won’t upgrade to a LEM.

Rear Sight in Front or Behind RMR?

People ask me all the time: “Irons in front or behind the optic?” In my opinion… it doesn’t matter. I believe both have enough pros and cons that neither is majorly superior over the other. When I shoot either of these pistols I have never once thought “wow, something is off… I can’t shoot this as well as the other because of the rear sight placement.”

Concern yourself with developing actual skill. Because THAT is what matters.

The Merkava 4 Barak brings AI to the Battlefield

The IDF just announced the newest generation of their Merkava 4 main battle tank, which benefits from some impressive upgrades. The armor is improved, the engine got a power boost, and the 120mm main gun has much better thermal characteristics… but some of the biggest new features are computer and software-based.

That main gun’s targeting computer is more accurate now, and can even compute firing solutions for knocking out airborne helicopters – with regular unguided anti-tank ammo – while on the move. But more importantly, the computer is constantly analyzing data from countless radar, video, and thermal sensors to identify, prioritize, and then automatically aim the turret at threats.

The tank’s three crew members can see all this stacked sensor data in the VR displays of their helmets, giving them a 360 degree view around the tank and overlays of target information. This isn’t really brand-new tech; helicopter pilots have had helmet-mounted displays for a long time, and the new F-35 helmet gives pilots a 360 degree view “through” the aircraft.

However, it’s the combination of a bunch these existing technologies in the Merkava that makes it interesting. The AI target identification computer combined with an advanced ballistics computer and auto-aiming turret means incredibly fast firing capability. The combination of a powerful central computer and VR helmets means that every Merkava 4 tank is also a Merkava 4 simulator (and tank mechanic training tool).

More importantly, the combination of many kinds of sensor data into a single view means much better decision-making for the tank commander. As cameras, thermal sensors, radar and radio equipment gets smaller and AI technology gets more advanced, we’re going to see more and more SIGINT work moving from human analysts to computers, and from large intelligence units to individual vehicles like aircraft and tanks. Eventually we will see some of these capabilities coming to individual soldiers.
