Daniel Defense DD MK18 (MIL-SPEC +) 10.3 „Pistol tactic AR-15 (cu braț) și configurațiile SBR cu polimer infuzat cu fibră de carbon DD 32-rundă 5.56mm / 300BLK AR Mag(Daniel Defense DD MK18 (MIL-SPEC+) 10.3″ Tactical AR-15 Pistol (with Arm Brace) and SBR Configurations with Carbon-Fiber-Infused Polymer DD 32-Round 5.56mm/300BLK AR )

DefenseReview (DR) nu a raportat deloc produsele Daniel Defense (DD), dar când ne-am oprit la standul lor, am fost intrigați de configurarea pistolului DD MK18 (MIL-Spec +) și de DD 32-round 5.56mm NATO (5.56x45mm NATO) / 300 Blackout (300BLK) AR Mag. DD 32-rounder este realizat cu poymer infuzat cu fibră de carbon, deci ar trebui să fie destul de puternic. De asemenea, vă permite să așezați cu ușurință 30 de runde în pistol (în acest caz DD MK18) cu șurubul înainte, fără nici o dimensiune suplimentară

DefenseReview (DR) hasn’t reported on Daniel Defense (DD) products for quite some time, but when we stopped by their booth, we were intrigued by the DD MK18 (MIL-Spec+) pistol setup and the DD 32-round 5.56mm NATO (5.56x45mm NATO)/300 Blackout (300BLK) AR Mag. The DD 32-rounder is made using carbon fiber-infused poymer, so it should be pretty strong. It also allows you to easily seat a full 30 rounds into the gun (the DD MK18 in this case) with the bolt forward, without any extra size. So, that’s nice.

The Daniel Defense DD MK18 (MIL-Spec+) complete upper and lower receiver sports a 10.3″ cold hammer forged barrel made from chrome moly vanadium steel, as well as an “Enhanced Flared Magazine Well” for fast reloads/mag changes. And, it gives civilian tactical shooters the chance to own the semi-auto-only version of the battle-proven select-fire MK-18 SBR (Short Barreled Rifle) that’s been utilized by US military SOF (Special Operations Forces) assaulters/operators for years, and has achieved a venerable reputation. Pretty cool. That said, full-disclosure, DR prefers 11.5″-12.5″ for barrel length on a M4A1-type DGI (Direct Gas Impingement) AR SBR. However, the 10.3″-barreled MK18 still works, albeit a bit too close to the reliability precipice for our liking.


By the way, the magazine itself is interesting enough to Defense Review that we’ve chosen to provide all the info and specs on it for our readers. So, here ya’ go (from the DD website):

“DD MAGAZINE®

The new DD Magazine is the only one worthy of the Daniel Defense name and is built with the same legendary quality and exacting standards as our world-class firearms. Its 32-round capacity for 5.56mm and 300 Blackout rounds is the most notable enhancement while maintaining the same size as industry-standard 30-round magazines. The DD Magazine surpasses the standard in strength and durability with its lightweight, cutting-edge carbon-fiber-reinforced polymer construction. An improved feed-lip design and an enhanced anti-tilt follower provide smooth, reliable feeding, while an impact-absorbing baseplate design adds to the magazine’s overall durability.

Ochelari de soare de luptă robust / tactici pentru misiuni militare de forțe speciale de operațiuni (Gatorz Eyewear Magnum Z Aluminum-Framed ANSI Z87+ Ballistic Eyepro: Rugged Combat/Tactical Sunglasses for Military Special Operations Forces (SOF))

O companie relativ nouă de ochelari de soare, numită Gatorz Eyewear, are un model foarte interesant din aluminiu ANSI Z87 + balistică cu balamale (modelul „flagship” de protecție a ochilor numit Magnum Z și este destul de impresionant în căutarea pe mai multe nivele. din aluminiu și cu o formă elegantă și imbracată în față. Și, în al doilea rând, se pare că va fi un adevărat interpret, atât în ​​ceea ce privește protecția balistică, cât și durabilitatea / rezistența la luptă.

Gatorz Eyewear Magnum Z Aluminum-Framed ANSI Z87+ Ballistic Eyepro: Rugged Combat/Tactical Sunglasses for Military Special Operations Forces (SOF) Missions! (Video!)

Posted by: David Crane July 16, 2018

A relatively new sunglass company called Gatorz Eyewear has a very interesting aluminum-framed ANSI Z87+ ballistic eyepro (eye protection “flagship” model called the Magnum Z, and it’s pretty impressive looking on multiple levels. First, the Magnum Z is aesthetically pleasing with it’s aluminum frame and sleek, face-hugging shape. And, second, it looks like it’s going to be a real performer, both in terms of ballistic protection and combat durability/ruggedness.

DefenseReview (DR) first came across Gatorz Eyewear Magnum Z at the First Tactical (clothing) booth at Industry Day at the Range, right before SHOT Show 2018, since one of their guys was wearing them. We immediately liked the look of them, so we decided to hit the company’s booth, which was close by. There, we ran into the very nice Jesse Buss, who let DR handle and photograph her pair. Finally, Gatorz Eyewear Brand Manager Andrew Fontes took us through the Magnum Z ballistic eyepro on video. The Magnum Z’s main claim to fame–aside from the aforementioned Z87.1+ ballistic protection level (obviously a great feature in a tactical shooting sunglass)–is its 7075 Billet Aircraft Aluminum frame, which is very eye-catching and immediately recognizable. DR immediately liked the Magnum Z’s frame design and high degree of comfort.

Comfort is obviously crucial in a combat/tactical sunglass that an assaulter/operator or civilian tactical shooter is going to be wearing on his/her face for hours on end under conditions that are bound to get a bit rough. To assist with this aspect,, the Gatorz Eyewear Magnum Z specs’ frame provides an “adjustable custom fit”. DR will try to glean more info about this.

Both pairs of Magnum Z ballistic tactical sunglassesDR saw and handled appeared to sport the smoked grey lens, which is designed to “maintain true color perception and greatly reduce eye fatigue from the sun’s glare.” The lenses themselves are TruRay Optics 100% UV Protection High impact resistant polycarbonate with an anti-fog coating.

Oh, and they’re made in the USA, by the way.

Defense Review REALLY dug the Magnum Z, and we can’t wait to run a pair (or two) at the range. We’re actually going to try to snag a pair for DR writer/contributor and chief new-product tester Jeff Gurwitch, since his US Military SOF background and competitive 3-Gun experience make him an ideal individual to evaluate them.

Chibrit ZKZM-500 cu laser din China: Carbonizatorul de piele înfricoșător sau puterea de propagare a puterii pure a poporului pur și posturarea?(Chinese ZKZM-500 Laser Rifle: Scary Skin Carbononizer, or Pure People’s Propaganda Power Play and Posturing?)

O companie chineză numită ZKZM, o „companie cu laser de fibre”, a proiectat și a dezvoltat o pușcă laser numită ZKZM-500, care se presupune că „carbonizează instantaneu” pielea cuiva de la un kilometru distanță. Scary, nu? ZKZM afirmă că pușca laser ZKZM-500 poate declanșa o explozie de 1.000 de raze laser de două secunde pe o singură încărcare a bateriei litiu-ion.

Chinese ZKZM-500 Laser Rifle: Scary Skin Carbononizer, or Pure People’s Propaganda Power Play and Posturing?

Posted by: David Crane July 3, 2018

Well, isn’t this a nice little gift a couple days before the 4th of July. A Chinese company called ZKZM, a “fiber laser company”, has reportedly designed and developed a laser rifle called the ZKZM-500 that can supposedly “instantly carbonize” one’s skin from one click (kilometer) away. Scary, no? ZKZM reportedly claims that the ZKZM-500 laser rifle can fire 1,000 two-second laser beam bursts on a single lithium-ion battery charge.

Now for the good news: The folks at big think are already reporting on some science-minded individuals casting doubt on ZKZM’s skin-roasting capability claims. Specifically, they’ve quoted the folks at TechCrunch as follows:

There’s just no way that a laser powered by a lithium-ion battery that a person could carry would be capable of producing the kind of heat described at point blank range, let alone at 800 meters.

That’s because of attenuation. Lasers, unlike bullets, scatter as they progress, making them weaker and weaker. Attenuation is non-trivial at anything beyond, say, a few dozen meters. By the time you get out to 800, the air and water the beam has traveled through enough to reduce it a fraction of its original power.

Let’s hope they’re right. big think’s verdict is that the ZKZM-500 is basically your run of the mill Chinese government/military propaganda designed to intimidate and dominate its own people into subservience.

Writer Ned Dymoke (interesting last name), puts it this way:

“The very idea of an invisible laser that can set you on fire is much more effective than the actual implementation of the weapon itself, because the only thing scarier than this gun is the idea of getting shot by it. In the wise words of my old English professor: ‘If you heard a rumor that your landlord had a shotgun, you’d sure as shit pay your rent on time.’”

So, still pretty bad news for the Chinese people, but good news for US (United States and our NATO allies).

Whew. Laser warfare crisis averted.

Lantac Razorback Complet Custom Glock 17 (G17) și Glock 19 (G19) Pistol de combatere / tactică și pachete complete de diapozitive cu bară cu filet suprimat și Trijicon RMR Red Dot Sight Combat Optic Instalat!

Acele arme se încruntă cu adevărat. Cu toate acestea, Lantac pare să facă niște pistoale Glock 17 (G17) și Glock 19 (G19) Grid 19 (G19) destul de slick și Razorback, care merită verificate, bazându-ne pe întâlnirea cu SHOT Show 2018. La urma urmei, nu există prea multe pistoale personalizate / personalizate Glock în colecția ta. Pur și simplu nu puteți exagera în această privință.

Lantac Razorback Complete Custom Glock 17 (G17) and Glock 19 (G19) Combat/Tactical Pistol and Complete Slide Packages with Suppressor-Ready Threaded Barrel and Trijicon RMR Red Dot Sight Combat Optic Installed!

Posted by: David Crane June 14, 2018

DefenseReview (DR) readers may already be aware that the Nous Defions Arsenal Democracy custom Glock-type pistols are currently our favorite Glock-type pistols, and that our latest favorite is their ND-AD Blackside 19MC (Mayhem Carry) compact 9mm combat/tactical Glock 19 (G19)-type pistol with SWiTCH Trigger and Mayhem Syndicate Carry Compensator Mk2. Well, if they aren’t (aware of that), they are now. Those guns really rock. However, Lantac would appear to be making some pretty slick Razorback complete custom Glock 17 (G17) and Glock 19 (G19) pistols and slide groups as well that are definitely worth checking out, based on our encounter with them at SHOT Show 2018.. After all, there’s no such thing as too many custom/customized Glock pistols in your collection. You simply can’t overdo it in that regard.

So, it was with that spirit that DR asked Jamie Franks of Lantac to take us through their latest and greatest Glock products at the booth, and we really liked what we saw, particularly the gun(s) set up with a suppressor-ready threaded barrel that was also crowned (nice touch). Everything felt and looked good on the Lantac Glocks that we handled, particularly the one shown in DR’s video below. Everything on that gun looked well-curated/chosen, including the Trijicon RMR red dot sight combat optic, which comes with both the complete pistol and complete slide packages.

Lantac also makes their own branded parts for Glock pistols, and all of those look interesting, as well.

Editor’s Note: Defense Review hasn’t shot the Lantac guns yet, so we’re only going off the guns’ feel and aesthetics at the moment, but both of those bode well for them. Our primary caveat at present is the reliability/durability of the Lantac E-CTG9 Upgrade Glock 17/19 Gen1-4 Trigger, since there are supposed high-end aftermarket Glock triggers out there that are a bit lacking in that aspect, particularly under hard use and high round count. The E-CTG9 may be terrific. We just don’t know yet.

Oamenii de știință au o explozie cu nanoparticule de aluminiu(Scientists have a blast with aluminum nanoparticles)

Oamenii de stiinta din armata au dovedit o predictie veche de zeci de ani ca amestecarea TNT si nanoparticulele de aluminiu noi pot spori semnificativ performantele energetice. Această descoperire explozivă se așteaptă să extindă puterea de foc a armatei americane în luptă.
Cercetătorii de la Laboratorul de Cercetare US Army si Universitatea Texas Tech a demonstrat până la accesoriu 30 la suta in viteza de detonare a TNT exploziv prin adaugarea nanoparticule noi de aluminiu, în care învelișul de alumină nativă a fost înlocuită cu o sare oxidantă numită AIH sau iodat de aluminiu hexahidrat.

Scientists have a blast with aluminum nanoparticles

(Nanowerk News) Army scientists proved a decades-old prediction that mixing TNT and novel aluminum nanoparticles can significantly enhance energetic performance. This explosive discovery is expected to extend the reach of U.S. Army firepower in battle.
Researchers from the U.S. Army Research Laboratory and Texas Tech University demonstrated up to 30-percent enhancement in the detonation velocity of the explosive TNT by adding novel aluminum nanoparticles in which the native alumina shell has been replaced with an oxidizing salt called AIH, or aluminum iodate hexahydrate.

The structure of the AIH-coated aluminum nanoparticles was revealed for the very first time through high resolution transmission electron (TEM) microscopy performed by ARL’s Dr. Chi-Chin Wu, a materials researcher who leads the plasma research for the lab’s Energetic Materials Science Branch in the Lethality Division of Weapons and Materials Research Directorate.
Wu said this revolutionary research offers the potential for the exploitation of aluminum and potentially other metallic nanoparticles in explosive formulations to extend the range and destructive power of Army weapons systems, a key objective of the Army’s „Long Range Precision Fires” modernization priority.
„We believe these results show tremendous promise for enhancing the detonation performance of conventional military explosives with aluminum nanoparticles for the first time,” said ARL’s Dr. Jennifer Gottfried, a physical chemist who collaborated on the research.
„It is very exciting to advance science to a point where we can harness more chemical energy from metal particles at faster timescales. This is an exciting time for transforming energy generation technology,” said Dr. Michelle L. Pantoya, the J. W. Wright Regents Chair in Mechanical Engineering and Professor at Texas Tech University.
Details of this breakthrough work are described in the team’s May 28 published paper „Improving the Explosive Performance of Aluminum Nanoparticles with Aluminum Iodate Hexahydrate (AIH)” by Jennifer L. Gottfried, Dylan K. Smith, Chi-Chin Wu, and Michelle L. Pantoya in Scientific Reports(„Improving the Explosive Performance of Aluminum Nanoparticles with Aluminum Iodate Hexahydrate (AIH)”).
The team found that the crystalline aluminum core was effectively protected against unwanted oxidation by the AIH shell, which appears as protruding nodules on the aluminum surface. The enhanced reactivity due to this unique morphological feature and novel core-shell structure was demonstrated by laser-induced air shock from energetic materials experiments, an innovative laboratory-scale energetic testing method developed by Gottfried. This technique involves impacting the sample with a high-energy, focused laser pulse to violently break apart the explosive molecules. The interaction of the laser with the material forms a laser-induced plasma and produces a shock wave that expands into the surrounding air. The energy released from an explosive sample can then be experimentally determined by measuring the laser-induced shock velocity with a high-speed camera.
It was predicted decades ago that aluminum nanoparticles have the potential to enhance the energetic performance of explosives and propellants because of their high energy content and potential for rapid burning. This is because they have exceptionally large surface areas compared to their total volume and a very large heat of reaction. However, the surface of the aluminum nanoparticles is naturally oxidized in air to form a thick alumina shell, typically 20% by weight, which not only lowers the energy content of the nanoparticles by reducing the amount of active aluminum, it also slows the rate of energy release because it acts as a barrier to the reaction of the aluminum with the explosive. Therefore, replacing the oxide shell, as successfully achieved by TTU, can significantly improve the explosive performance.
These preliminary joint efforts have also led to a formal research collaboration under an ARL Director’s Research Award, the fiscal 2018 External Collaboration Initiative between Wu and TTU.
After publishing two papers in high-impact scientific journals in the past year, the team is poised to pursue additional energetics research with aluminum nanoparticles by working with the U.S. Army Research, Development and Engineering Command at Picatinny Arsenal, New Jersey, and the Air Force Research Laboratory.

Magpul Cover Suppressor – 5.5 „pentru Rotunde 5.56mm Trucuri pentru tunuri NATO (Silencers / Supresoare de sunet) în timpul Combat Ops: Reduce caldura supresoarelor externe și semnătura termică

Capacul de supresoare Magpul – 5,5 „este alcătuit dintr-un manșon din polimer rezistent la căldură suprapus peste un scut încălzit din oțel inoxidabil, care se montează direct pe corpul supresor cu cleme din oțel” care „minimizează transferul de căldură pentru a menține temperaturile de acoperire externe până la 1000 grade F mai rece decât suprafața supresorului și permite răcirea fluxului de aer în recipient. În plus, servește ca dispozitiv izolator termic îmbunătățit și dispozitiv de reducere a semnăturii, reducând în mod semnificativ distorsiunile mirajului la imaginea de vedere a shooterului, reducând probabilitatea de deteriorare a impactului asupra corpului supresor și diminuând șansele de accidentare accidentală a calității sau deteriorarea personalului sau echipament în timpul arderii armei și răcire

Magpul Suppressor Cover – 5.5″ for Round 5.56mm NATO Muzzle Cans (Silencers/Sound Suppressors) during Combat Ops: Lowers Outer Suppressor Heat and Thermal Signature! (Video!)

Posted by: David Crane June 10, 2018

DefenseReview’s (DR) found that it’s often the little things that can make your life a lot better and/or easier. Assuming it works as advertised, the Magpul Suppressor Cover – 5.5″ (5.5 inches) is one of those products. When it comes to guns heat’s the enemy in a whole bunch of ways, particularly with rifle/carbines, and even more particularly with select-fire rifle/carbines, including those in 5.56mm NATO (5.56x45mm NATO) caliber. Anyway, the Magpul Suppressor Cover – 5.5″ (5.5 inches) is specifically designed to cover 1.5” outer diameter/5.5″-long round cans (silencers/sound suppressors) like the popular Surefire SOCOM556-RC2 muzzle can (silencer/sound suppressor), and it would appear to be very well designed for that purpose.

The the Magpul Suppressor Cover – 5.5″ consists of a “heat-resistant polymer sleeve overlaid onto a raised stainless steel heat shield that mounts directly to the suppressor body with steel clamps” that “minimizes heat transfer to keep external cover temperatures up to 1000 degrees F cooler than the surface of the suppressor and allows cooling airflow across the can. Additionally, it serves as an enhanced thermal insulator and signature reduction device, significantly mitigating mirage distortions to the shooter’s sight picture, reducing the likelihood of impact damage to the suppressor body, and lessening the chance of accidental heat-related injury or damage to personnel or equipment during weapon firing and cool down.” Sounds pretty good.

When you’re involved in a high-speed, low-drag dynamic combat op involving a lot of moving, and perhaps even climbing and/or repelling, the last thing you need is a hot suppressor burning through your clothing or skin. So, why make life any harder than it has to be?

Oh, and the the Magpul Suppressor Cover – 5.5″ even lowers your can’s thermal signature, and attenuates/mitigates the mirage effect on your sight picture. Handy.

The following are Magpul Suppressor Cover – 5.5″ features, straight from the company’s website:

– Extreme temperature protection that mitigates internal suppressor temperatures to safe levels
– Minimizes retained heat, allowing faster cooling than any other suppressor cover technology
– Reduces thermal signature of host firearm
– Mitigates mirage effects in sight picture
– Two stainless steel clamps provide a strong, rigid and reliable interface capable of sustained firing sessions and rough handling
– High temp polymer sleeve withstands brutal suppressor temperatures during extended periods of firing without deterioration
– High strength corrosion resistant stainless steel heat shield

Additional sizes for different can sizes and calibers are supposed to be avalable soon.

Anyway, DR like’s the this product, and looks forward to trying it out at some point. In the meantime, check out Defense Review’s video on it, below.
