Have you ever had an idea you thought was utter genius, something no one has come up with before…only to find out later that, yes, it’s already been done? That’s how I feel about Raven Concealment Systems and the ModuLoader. Years ago, a friend of mine was messing around making Kydex holsters and mag pouches, and we talked about building a simple Kydex platform to which we could mount velcro shotgun cards.

It turns out Raven Concealment Systems had this idea long before we did in the form of the ModuLoader. However, it was an idea that didn’t do well at the time, and Raven discontinued the ModuLoader.

Imagine my joy when news drifted into my email inbox that the ModuLoader was back. According to Raven Concealment Systems, the resurgent popularity of shotguns suring the pandemic inspired them to give the product another go.

As I type this, Raven still has ModuLoader kits up for sale. These are a limited run item, and RCS is selling the loader and two five-shot elastic cards for $50.

I grabbed one a couple of weeks ago and before this gets published, I’m buying another one in case they disappear again.

Breaking Down the ModuLoader

The ModuLoader is a two-part system. The first part is the elastic shotshell cards. Raven includes two with your purchase. Each shotshell card holds five rounds of 12 or 20-gauge shells. The back end is covered in Velcro hook material. That hook material allows it to connect to anyplace you have a patch of loop. Ares Gear makes these specific shotshell cards.

The second part of this setup is the ModuLoader platform. This is a polymer panel with a field of hook material you use to attach one of the shotshell cards. Additionally, the platform has two loops you can use to attach the shotshell carrier to your belt.

The second part hooks to the belt and conforms to your body well. (Travis Pike for TTAG)

The idea is simple enough. One shotshell card rides on your shotgun and another on your belt. When you fire the ammunition from your shotgun and from the shotshell card, you can remove the empty card and replace it with the fresh card from your belt. It’s easy, handy, and affordable when compared to similar systems from companies like Aridus Industries.

The ModuLoader In Theory

The general idea might be to replace the empty side-saddle with another side saddle, but that’s a limited way of using the ModuLoader. You could simply carry the ModuLoader as a way to carry belt-mounted ammo if a side-saddle doesn’t work with your gun. Plenty of people still use and enjoy double and single-barrel shotguns, and the ModuLoader offers you some on-the-belt action for quick and intuitive reloads.

On top of that, shotguns fire all sorts of different types of ammo. You can belt-carry slugs and keep buckshot in the side saddle. The chance of using all your shotgun ammo in the gun and side saddle is highly unlikely. However, you might need to switch to a slug, or police and military users might need to switch to breaching rounds.

Double barrels benefit as well. (Travis Pike for TTAG)

Heck, I’ve switched from buckshot to turkey shot while hunting in my own clumsy manner. Having a mix of slugs and turkey shot, even No. 4 on my belt, gives me plenty of options to take deer, hogs, turkeys, and coyotes at various ranges. It’s easier to carry ammo on your belt than fishing around in your pocket.

I see a lot of versatility with the ModuLoader.

Putting the ModuLoader Into Action

But theory isn’t good enough. We gotta take things out and beat them down, try them out and see if they’re worthy of your hard-earned dollars. I strapped up the ModuLoader on my 5.11 Matrix belt and put an elastic card on my Mossberg 590A1. Then I headed to the range…and the kitchen.

The elastic loops are tight, but give up the shells easy enough. (Travis Pike for TTAG)

Actually, I started in the kitchen. Not for a snack, but for a little dry fire practice with some dummy rounds. It’s gone from spring to summer hell here in Florida, so in the middle of a Saturday, I’m not trying to die while reloading.

The dummy rounds do most of the job anyway when reloading shotguns. Loading the cards is tough because the elastic loops are freaking tight. But once in place, they stay there. When it comes time to peel one out and slap it into the loading port, it won’t challenge you. Grip, rip, and load. The Velcro sticks tight and doesn’t give out when peeling a round from the card.

Detaching the empty carrier and remounting a ful lcarrier is where the magic is at (Travis Pike for TTAG)

The real magic is obviously removing the carrier from the ModuLoader and slapping it onto the gun. I wish the elastic card had the little paracord pull loops Esstac uses on their cards. Even without the loop, though, it’s easy to tear the card off and replace it with the spare carrier.

At that range, that much ammo allows me to lay down what’s effectively suppressing fire as long as I don’t fat-finger a reload. Ten spare rounds is a lot of ammo for a shotgun, and it’s nice to see more modern and modular reloading options.

Shotgun Nerds Unite

The ModuLoader is an awesome option that provides a way to carry not only spare ammo on your belt, but the ability to take that spare ammo and slap it onto your firearm. I love the idea and think I need at least four more to deck out my battle belt. I guess I better dial in those credit card digits before Dan hits publish.

  1. I tried those side saddle things, all that happened was the shells got lost when I was dragging the shotgunm behind me.
    Are these dragging through brush rated 5*’s or1?

    • You need a tail accessible possum travois, keep yer gunms n shootms up outta the dirt. Think of it as a male marsupial manpurse…

  2. When I was required to carry a shotgun I had a Scattergun Technologies 870 with a side saddle shell carrier. Four round. The author’s argument of swapping carriers from belt to gun and back, buckshot to slugs and back, seems a bit complicated. I’ll take a rifle. It works equally well from three to three hundred yards with the same ammo. And trust me, a centerfire rifle wound, especially with soft point ammunition, can be as equally impressive as a shotgun wound.

    • “I’ll take a rifle. It works equally well from three to three hundred yards with the same ammo.”


      Outside of a shotgun with a rifled barrel, what rifles shoot 12 gauge shotgun ammo?

      • Bolt-action 12 gauges are a thing. Some states are shotgun only for hunting and its a way to get a bit more downrange accuracy out of a slug round.

      • Geoff, maybe I wasn’t clear. If given a choice, I’ll take rifle instead of a shotgun. Everytime.

        • I feel differently, and if you will hear me out, I will explain.

          I have a rifle on my person nearly all the time, shorty pistol BO folder in courier pack backing up a pistol. Most real world situations would dictate shotgun being superior given the avg. usual engagement range of ~15m in the U.S. for those not in an actual war, and discounting certain mass shooting events. Yet the shotgun remains in the trunk with a heavier rifle, for the same reasons. To bulky, not concealable, and short on quantity, given similar weight of ammo.

          Now I can hear you’re nodding your head in agreement. I know. Here’s where we diverge.

          I have what I need on my person to fight my way back to it, should the situation dictate it being the best tool for the task at hand. Were it perfect in the real world, I would rather the shotgun be in the pack instead. Here is why.

          If you had ever seen an full auto shotgun at work you would understand. This one isn’t, but it’s bump fire on easy mode and has both the very best trigger and brake possible, which also makes it close to, if not the flattest shooting shotgun in the world. Split times are ridiculously low even without bumping it, .15 avg. .11 with. Fire hose, on.

          Talking practical:

          Don’t care who you are, or what armor you’re wearing. Within it’s range no one, bar none, is walking away from 20 high power buck or slug in less than 3 sec. Carried away is the best that can be hoped for, and that only if wearing Lvl IV or greater type gear and taking plate shots only, without shooting for major joints, femoral, or head. Will be, right after I center punch their plate to stagger them if I suspect, or immediately if know they are armored up like that.

          Best part? On empty, 20 more ready to send less than 3 sec later if I do my part and don’t fumble the reload, which is easy-peasy with a flared magwell. Then 12, then 12 more, and again. And again. And again.

          Then I’m going to shoot them with something else; that’s all the ready stores I have in the trunk. 😀

          The Lady doth protest:

          “No off the shelf shotgun can do that”. Correct, mostly. Some NFA items can, somewhat. But they are also lesser than this one in many respects. I would suggest viewing open class shotgun divisions for an eye opener. With the reminder; they need not be built exclusively for light target loads. Reliability and high power can be the focus too. Btw, this one is fine tuned by the those who built what you saw dominating the open classes. U.S. Army shooting team uses the same, by the same people too.

          You have made it abundantly clear over the years that you despise shotguns. We know, you say so on nearly every shotgun related article since you’ve been here despite abundant evidence to the contrary. But you also haven’t given the right ones a spin either. This one is unlike anything you’ve ever laid hands on before.

          And with a price tag between $4.1k to pushing 7k as built these days, not many will. Irrespective of the fact that supply for the base gun is near completely exhausted..

          Here, run the numbers for yourselves.

        • AR in Win Mag next to the shotgun in the trunk. Pawns .450 any day. Better invest in reloading, or gl finding ammo when the SHT oscillator device. Also, .458 & .50 Beowulf is better.

    • Yeah but a riffle is on theBiden’s sht list.
      Shotgunms are President approved and recommended.

  3. Every single time I see a review on a piece of equipment like this, it is stated good for 12 and 20 ga. shells. I guarantee it will work with 16 ga. shells too. Nobody ever remembers that folks still use 16 ga. guns. I just recently bought two 16 ga. shotguns, because I want to be able to shoot any ammo I can scrounge, beg, barter or steal when the manure hits the ventilator.

  5. Guns are now my weakness:) already a few years I collect weapons have not long been able to still get a shotgun Kel-Tec KSG, which I was looking for so long:) but in honor of this, I am ready to share a good and quality site which is dedicated to what they say in detail, what are free games with dangerous fruits, as well as what they have bonuses, in addition there is still a list of all such games, so feel free to go read and choose what you like.
