Over the 40 plus years the NIJ has been certifying body armor, much has changed. Back in the late 60’s, through the 70’s and early 80’s, handgun threats on the streets escalated from .38 SPL RNL and .22 LR out of short barrels to hot 9mm FMJ and .44 Magnum JSP. The level I rating virtually disappeared as a result (though it is still better than nothing, see my shoot tests with Level I panels).

But perhaps the biggest changes have been in the area of rifle threats, specifically AP (Armor Piercing). At the outset, NIJ level IV was rated to stop arguably the most potent threat that could be regularly encountered (and all comparable but lesser threats), the .30-06 M2 AP 163gr. At 2750 FPS, this round was (and still is) formidable. Having a high molybdenum and vanadium tool steel core hardened to around 59-61 Rockwell C hardness, it can punch through 8mm of RHA at 100M. Comparable Soviet and ComBloc rounds do slightly worse.

But fast forward more than three decades, and the threat profile has changed. WC (tungsten carbide) core rounds are no longer a rarity, and their penetration profile is far better than the M2. The American military has recently introduced a second generation WC projectile as a replacement for the first generation M993. Called the ADVAP (Advanced Armor Piercing) round, it is essentially the same design as the M80A1 projectile, with a hardened WC “arrowhead” swaged to a copper alloy base/driver. At $13 -per round- it is designed to cope with advanced emerging armors.

Which means the threats are not unilateral. Advanced Russian and Chinese designs must be assumed to be at least comparable to the M993 (7.62), M995, and AP4 (5.56) rounds. Which is why the NIJ is strongly encouraged to drop the M2 AP as the baseline round for the highest rated rifle plates, and begin using the M993 (as sourcing the newest Russian rounds for testing is virtually impossible at this time).

Testing by Buffman, of BuffmanRange has shown that there are plates that are (barely) capable of stopping the M993 round (and by extension, the M995 and AP4), but it is a crap-shoot. They are neither designed, nor rated for WC threats, which necessitates a completely different design philosophy.

The second problem is that of fragility. The current NIJ IV rating specifies a SINGLE M2 AP round must be stopped, in order to meet the standard. The NIJ III is not much better, specifying 6 rounds of M80 ball in a 6″ circle. In nearly every case, the plate is reduced to rubble, with the entire strike face compromised after a single round. A more reasonable standard is to require 8 rounds in a 6″ circle, for both levels of plate. More difficult? Absolutely. But in keeping up with advancing threats, absolutely necessary.

Here at D-Rmor Gear, we are not satisfied to rest on our laurels, and have been working on these problems tirelessly over many years. As a result, we will have a major announcement by the end of the month. Stay tuned.

Modern armor leans rather heavily on a class of materials known as ceramics. Man has been developing and using ceramics since antiquity, and they still play a vital role (some would say even more so now) in the 21st century.

But instead of amphorae to hold wine, olive oil, or other bulk trade goods, ceramics are used in more demanding applications, where extreme heat, pressure, abrasion, and corrosion resistance are critical.

For applications in body armor, ceramics must exhibit several seemingly contradictory attributes, of which four are absolutely critical. They are:

Bulk Density: This translates into how heavy a ceramic is for a given volume. The lower the number, the better.

Hardness: This is a ceramic’s resistance to indentation. Harder is better, especially when facing tungsten carbide core threat projectiles.

Fracture Toughness: How resistant to crack formation and propagation a ceramic is. The higher the number, the more suitable as armor.

Modulus of Elasticity (Also known as Young’s Modulus): This describes how stiff a material is  (elastic deformation). The higher the number, the stiffer it is.

There is also another vital attribute to consider, which is cost. There are several ceramics that would be considered “ideal,” but are disqualified due to prohibitive cost. I have provided the attributes below, as well as a numerical rating from 1 to 3 (1 being least efficient, 3 being most efficient). Below a usable threshold will result in a 0. This will allow us to see how each ceramic stacks up.

The three primary technical ceramics that account for 95% of the ceramic armor currently used (personnel and vehicular) are:

Aluminum Oxide (AKA Alumina, Al2O3)

Silicon Carbide (AKA Carborundum, SiC)

Boron Carbide (AKA Black Diamond, B4C)

The traits and attributes are as follows:

Al2O3-

Bulk Density (99.5% grade): 3.90 g/cm3 (1, heavy)

Hardness: ~1400-2000 Knoop (Kg/mm2) (2, low-medium hardness)

Fracture toughness: 4.5 (2.5, very good)

Elastic Modulus: 393 (1.5, low)

Cost: $ (affordable)

Overall rating: 1.9 out of 3

SiC-

Bulk Density (Sintered): 3.21 g/cm3 (2.5, medium weight)

Hardness: 2800  Knoop (Kg/mm2) (2.5 high hardness)

Fracture Toughness: 4 (2, good)

Elastic Modulus: 475 (2.5 medium-high)

Cost: $$ (expensive)

Overall rating: 2.3 out of 3

B4C-

Bulk Density (Hot Pressed): 2.51 g/cm3 (3,extremely light)

Hardness: 3500 Knoop (Kg/mm2) (3,extremely hard)

Fracture Toughness: 2.6 (1,low)*

Elastic Modulus: 675 (3,extremely high)

Cost: $$$ (extremely expensive)

Overall rating: 2.2 out of 3

So, as can be seen, there are numerous factors involved. While Boron Carbide is the hardest of the commonly used ballistic ceramics, it is not the best overall. Silicon Carbide takes the honors, having the best combination of factors. If weight is paramount, B4C is the leader.

By comparison, the following are the attributes for Silicon Nitride, an “ideal” ceramic for ballistic applications:

SiN-

Bulk Density: 3.31 g/cm3 (2.3, medium heavy)

Hardness: 2200 Knoop (Kg/mm2) (2.3, medium hardness)

Fracture Toughness: 7 (3, extremely high)

Elastic Modulus: 317 (1.5, low)

Cost: $$$$ (prohibitively expensive)

Overall rating: 1.82

And the attributes for fused silica (SiO2, glass)-

Bulk Density: 2.2gm/cm3 (3, very light)

Hardness: 600 Knoop (Kg/mm2) (0, below usable threshold)

Fracture Toughness: 1 (0, below usable threshold)

Elastic Modulus: 73 (0, below usable threshold)

Cost: $ (very inexpensive)

Overall rating: 1.2

So, as can be seen, multiple factors are in play when selecting optimal ceramics for ballistic use. Looking at just one, or even two will not give a complete picture.

Which is why most ceramic armor for rifle and larger caliber applications is either Alumina (most effective ceramic for the money), or Silicon Carbide (best performer for the money).

And until revolutionary advances are made in the field of nanotechnology and technical ceramics, the three main materials listed above will be soldiering on for the forseeable future.

*Special note about Boron Carbide- B4C undergoes what is known as “amorphization” under impact loading. In layman’s terms, the crystalline structure of the Boron Carbide is converted to a glassy (amorphous) structure when impacted at high speed. This causes a tremendous loss of strength. The reasons for this impact-loading loss of strength is still not fully understood, and ongoing research is attempting to remedy it. Neither Al2O3 nor SiC undergoes this transition.

We have placed our version 4.4.1 Spall Guard orders on hold due to material shortages. The mill that custom produces the material is backed up about 90-120 days.

Please email us to get on the notification list, and we will keep you apprised of the status.

Thanks for your patience, and patronage.

Over the past 15 years, we have been designing, building, innovating, and improving armor, tactical gear, and related equipment. Our philosophy has ever been, “there’s no such thing as over-engineering, merely proper engineering.” After wearing out, destroying, and dissecting more pieces of personal gear than we can recount, there were some themes that kept repeating: stitching geometry, materials, and design are all critical. It sounds like common sense, but after witnessing many gear failures, and tracing them to their causes, we saw that common sense is not so common.

We began to design gear that incorporated advanced materials. Materials normally only found in ballistic armor, such as Kevlar and Twaron. We sought out the best materials, and when they couldn’t be found, we had them custom milled to our specifications. And we realized that using ballistic-rated materials could enhance the overall protective capabilities of the entire system, meaning that pouches and load-bearing gear was no longer pure parasitic weight.

The results of that decade of design, planning, innovation and re-design are now available to you, a dividend that you can benefit from when you purchase any of our FragTuf(TM) gear.

When you see the FragTuf(TM) name, it means that the item is stronger, lighter, better. There are three levels of FragTuf(TM) construction:

FragTuf-A: Utilizes our signature dual-stitching, combining mil-spec Kevlar and Nylon. Can also include advanced HANK (High Abrasion Neoprene Kevlar) laminate.

FragTuf-B: Includes everything found in FragTuf-A, but goes a step further, and contains between one and three layers of fifth-generation woven ballistic aramid.

FragTuf-C The most rugged FragTuf gear includes everything A and B has, with the addition of our custom-milled SpallGuard aramid material, usually in places other makers would use mundane padding.

Our goal is to create a comprehensive line of gear, that is both universally compatible with everything we make, as well as interchangeable and compatible with as much extant gear (current, future, and legacy) as possible. To give you the absolute maximum number of possibilities in setting up your kit, with the absolute best quality and durability.

Everyone loves Kydex. It makes for durable, lightweight, rigid holsters, mag pouches, and knife sheaths.

However if you want to attach a Kydex sheath to a MOLLE panel, or have a blade you want to run on a dundee rig, a drop-leg setup, or attach to a pack…the Kydex leaves much to be desired. Zip-ties or paracord lashing keep the low-profile of the original sheath, but are somewhat…low-speed. Other methods using screws and polymer hardware work, but add significant weight and bulk.

Enter the D-Rmor Gear KTM (Kydex-To-Molle) sheath adapter. Constructed of 1″ Mil-spec nylon webbing and rugged 500 denier solution-dyed Cordura, the KTM adapter gives you an abundance of mounting options. With the use of ITW G-Hooks, Tactical Tailor MALICE Clips, or split-bar side release buckles, you can mount your knife tip-up, tip-down, or horizontally. Set it up as a Dundee shoulder rig, a drop-leg rig, or mount it to your ruck or plate carrier. The KTM boasts four mounting loops and double-sided MOLLE compatible mounting webbing, in addition to a paracord tie-down integral to the design.

The KTM offers positive integration and retention of the Kydex and KTM, resulting in a secure, comfortable, versatile, and low-profile upgrade to your favorite sheath and blade combo.

Intended to work with quality Kydex sheaths (such as those offered by Al Welke of AZWelke Sheaths), the KTM can be crafted for both pancake and taco style kydex sheaths.

Pricing will vary by size, knife shown is a Busse SWatmandu Taco sheath by AZWelke, and would run $49 as-equipped (sheath and blade NOT included). Each KTM is customized to your sheath, and requires end-user to mail sheath with payment.

Color options are Coyote, Black, Multicam.

If you carry a magazine-fed long gun, it’s a snap finding good pouches. There’s a virtually endless selection.

Carry a shotgun? You have about three choices: cumbersome pouches, even more cumbersome bandoleers, or cards. And most if not all of those cards use elastic that goes flaccid after use. Not something you want retaining your ammo in a critical situation.

With an eye towards fixing that, D-Rmor Gear has developed the Enhanced Shotgun Card. Built with the usual D-Rmor Gear attention to detail, the FragTuf(TM) Enhanced shotgun cards go far beyond the norm.

Incorporating D-Rmor Gear’s new FragTuf(TM) technology, all critical seams boast dual-stitched mil-spec Nylon AND mil-spec Kevlar thread. The shotshells are retained, not with wimpy elastic (that WILL lose its tension in short order), but with MIL-A-A-55301 IR/Berry compliant webbing. A Trelleborg AB HANK pull-tab completes this rugged ensemble. The hook-covered rear surface allows mounting to any loop-covered field.

And as if all of that isn’t enough, the Enhanced Shotgun cards come with an unlimited, lifetime, fully-transferrable no-bs guarantee. If you break it (and please tell us how you managed that!), just get it back to us, and we will repair or replace at our discretion.

Initially available in 3-, 5-, and 7-shell configurations, the D-Rmor Gear Enhanced Shotgun Card can be had in Black, Coyote, and Multicam colorways.

Normally priced at $15, $18, and $22 respectively, get yours at the pre-sale price of $12, $15, and $19! (Pre-sale good through February 1st).

Every once in a while, an old design needs an update. Sometimes it’s small, and sometimes it’s big. We think the new D-Rmor Gear HatchBack Shotshell Card falls into the latter category.

If you carry a shotgun and a plate carrier, you know that there isn’t very much love from the gear world. There are either cumbersome cards that don’t really fit, or bandoleers/slings with elastic that wears out and drops shells when you need them most. And then, you have the choice of either MOLLE, or loop backed carriers, but you have to choose one.

Enter the HatchBack. Designed to do three things better than any other shotshell carrier on the market:

-To SECURELY hold three 12G shotshells of any size, while allowing quick access

and

-To enable the card to be used on either MOLLE grids OR loop fields.

and

-To exceed the durability of any extant shotshell card

To address the first criteria, D-Rmor Gear created a card that utilizes 1″ Berry and IR compliant Nylon webbing, which firmly grips the shells, and will not fray, sag, or lose elasticity (like ALL elastic shell holders will with use). Is it more difficult to build? You bet. But once you try it, you will realize why it leaves elastic shell holders in the dust.

The second criteria is where the HatchBack gets its name. With the use of Velcro OneWrap(TM), the Hatchback lets the user go from MOLLE to loop field in seconds. On MOLLE fields, a front flap protects the shells while keeping them at the ready, while for loop-field use, the shells are free to be used in either orientation.

The final criteria is fulfilled courtesy of D-Rmor Gear’s revolutionary FragTuf(TM) construction methods. Using a dual-stitching method, we combine mil-spec Nylon AND mil-spec Kevlar thread into every critical seam, as well as incorporating Trelleborg AB’s rugged HANK material.

No other shotshell card offers you the versatility, security, and durability of the HatchBack. Made with innovation and the absolute best materials and workmanship available.

Plus, it comes with a lifetime, unconditional, fully transferable, no-BS guarantee. If you break it (and please tell us how you managed it!), just get it back to us, and we will repair or replace at our discretion.

Initially available in Black, Coyote, and Multicam, with more options planned.

Pricing is $32, with a special pre-sale price of $26 until February 1st.

After five years of testing, design, retesting, and redesign, the wait is over: announcing the D-Rmor Gear Enhanced Weapons Sling.

With so many slings on the market, how could there be any room for improvement? Well, for starters:

-Trelleborg AB HANK or low-profile padded shoulder pad

-Ruggedly built, with all critical seams stitched with both mil-spec Nylon and Kevlar threads

-Convertible 2-1 with two onboard methods, with emergency bailout Ghillietex buckle or Nexus D-ring for HK clips.

-Primary body made from MIL-A-A-55301 IR and Berry compliant 1″ webbing to be compatible with ALL end-user sling hardware.

-24 inches of built in adjustment, with 13″ of quick adjust.

-Unconditional, no-BS lifetime guarantee, repair or replace.

Finally, in spite of the premium materials, the extra time required to build, and the innovation, the AE-SIR was intended to be as affordable as possible. You don’t have to break the bank to equip all of your long guns with what we believe is one of the best slings for the money.

Available in Black, Coyote, Multicam Original, Multicam Black, Multicam Alpine, ATACS-AU, ATACS-FG, Kryptek Typhon, Kryptek Mandrake, and Kryptek Highlander, with more patterns planned.

Pricing is normally $44, and $51 (for the XL and Padded versions respectively) per sling, but limited pre-sale price is $39 and $46 per sling (pre-sale ends Feb 1st).
