Maxim Defense MD-1505: An AR Take on the PDX


The PDX from Maxim Defense has proven to be an extraordinarily popular design over the last few years, but it has (understandably) never been on the lower end of the firearm price point scale. They have now launched the “MD-1505”, to make a more affordable AR-15 style PDX available. Though similar to the PDX in size and capability, the PDX has MILSPEC forged receivers and a different handguard. With the SCW stock, SCW brace, and SCW pistol system options, there should be a version available for most conceivable needs.


Here’s what Maxim had to say,

Maxim Defense MD-1505

When you’re looking for Maxim Defense PDX ingenuity in a standard AR-15 package, the MD-1505 is your answer. The MD-1505 was engineered to bring our top-tier PDX package to an even more affordable price point.

Starting at the muzzle, each MD-1505 is equipped with the patented Maxim HATEBRAKE muzzle device, which reduces recoil, decreases flash signature, pushes gasses, and concussion wave downrange away from the operator. All of which improve overall performance in short barrel pistols and rifles.

For increased comfort and versatility every MD-1505 features our free-floating Slimline Handguard. These handguards provide a monolithic-like upper receiver platform and M-Slot compatibility on five sides. At the rear, the MD-1505S is equipped with our SCW Stock for the ultimate in compactness, comfort, and versatility.

MD-1505 Affordability

MD is well aware that “affordable” is an extremely subject term. Those who will immediately react negatively to the MSRP, know this: Maxim Defense has never sacrificed quality for a reduction in cost. Their description says more affordable, not “easily affordable” or any other permutation thereof. In the specific case of the MD-1505 vs. PDS, it is more affordable. That said, quality speaks for itself. The price point will not be for everyone.

HRT Modulus Chest Rig Review

HRT Modulus Chest Rig Review
The Modulus Chest Rig

By: Fifty Shades of FDE

HRT Tactical knocked it out of the park with their RAC Plate Carrier, which I reviewed thoroughly last year. The RAC is still my go-to and preferred plate carrier. So when the guys from HRT Tactical reached out to me about their upcoming chest rig, I was excited to see what they come up with. I got an advanced kit and have had time to test it out for myself.

The Modulus Chest Rig is true to it’s namesake by being very modular in design, just like the RAC Plate Carrier. It makes it very easy to switch out pouches to fit whatever your current needs.

Let’s get into the use of chest rigs. They do have a purpose for certain situations and like any other piece of kit, there are advantages and disadvantages to each. Knowing the capabilities of your equipment is the key. This is from my own experience and usage of gear for over a decade of use in training and at work. Granted, I am not a military veteran or was ever on a tactical team; I’m just a regular Law Enforcement Officer that trains as much as possible and have had the opportunity to use and review quite a lot of plate carriers and chest rigs.

Inside the Admin Pouch.

So why would one run a chest rig over a plate carrier with rifle plates? Everything is mission dependent with many factors in play. With a chest rig, your advantages are weight savings, lower profile (depending on the carrier), ability to carry extra magazines and essential equipment. With a chest rig, you have a higher mobility and agility over a plate carrier, however you must know the disadvantages. The obvious one is the lack of ballistic protection from the rifle plates that are in a plate carrier as well as less surface area for more equipment, this can be either an advantage or disadvantage. Like I mentioned before, it’s all mission dependent and personal preference.

Loaded to my specifications and preference.

The chest rig is perfect for the training environment and I find it to fit in the same category of bump helmets, they both lack ballistic protection but are much lighter. In a training environment, you’re not worried about incoming fire, outside of ricochets or NDs. In the field, they can be used in place of plate carriers if you need a lower profile to blend in or something quick to throw on to have more firepower on your person or are in an environment such as in higher altitude where weight savings is a bit more important than ballistic protection. There will always be a balance between mobility versus protection so each individual has to weigh in and make a determination on which piece of kit to use. If one is more mobile and faster, they are a harder target to hit, you get the picture. These are just examples from my own experiences being in kit.

The mesh panel for the back adds comfort and breathability.
The pouches have bottom tabs to add stability when attached to the Modulus.
Removing or installing the pouches are simple to accomplish.

Lower profile chest rigs as well as plate carriers are becoming more popular. The Modulus is no different. It’s light weight and has a low and flat profile. What sets it apart from the rest is the ability to quickly swap out the front pouches to fit your current needs and requirements. You have the option to run it slick to carry three AR-15 rifle mags or add an admin pouch or a pistol mag pouch in any configuration suits you. You also have the option to run open top or covered with the pistol mag pouches. This makes it great for the end user to customize their Modulus to work for them. As well as most chest rigs are well designed, they may not work for everyone. The Modulus ensures that it will adapt to any mission that a chest rig can be used for.

Run the Modulus anyway you want!

The Cordura, stitching, zipper as well as the velcro are of high quality. All of the straps have a retention elastic band to help secure the loose ends, which is something that I appreciate.

Side profile.

The Modulus Chest Rig takes after the RAC Plate Carrier in the same form where it too maximizes the modularity of the chest rig platform to a fit numerous parameters for the end user.

Want to run open top on your mag pouch? Just remove the cover. It’s nice to have options!

The guys at HRT Tactical have come out with another hit and these will be available soon after this review is published.

New Micro Pistol: Taurus GX4

New Micro Pistol: Taurus GX4

By: Fifty Shades of FDE

New from Taurus is their GX4 pistol, a lightweight micro compact pistol chambered in 9mm that holds 11 rounds in a flush magazine with a msrp of….$392.42!

The Taurus GX4

Ever since Sig Sauer came out with their P365, something I personally carry everyday; many other companies are following suit and that’s a good thing for consumers. The more options, the better, in my opinion. Not everyone can afford certain pistols and not every pistol works well with every end user. With the current demand for firearms, the more models in production is always a plus.

New ASP Enhanced Red Gun: HK416

New ASP Enhanced Red Gun: HK416

ASP HK416 Enhanced Red Gun


    The New ASP HK416 Enhanced Gun

By: Fifty Shades of FDE

Over my entire career in Law Enforcement, dating way back to when I was a teenager Police Explorer, I have been using ASP Red Guns for training. ASP is best known for their impact weapons, particularly with expandable batons as well as other law enforcement related gear. Red Guns are essential for safe training events where using live weapons is unnecessary and or too dangerous to have in certain environments.

There is no mistaking a Red Gun for a real firearm.

ASP Red Guns are most common in the form of handguns and pistols. They do, however make long gun versions as well. The new Enhanced Red Guns are a new and improved offering from ASP that features a functional magazine well and magazine release button. The model I received is molded from the Heckler and Koch HK416 with a 16″ barrel. It has an additional feature with removable rails in the foreend, a flat top upper receiver and a front optional sling mount. It comes with two inert red magazines modeled after the Hex mags.

Comes with two inert red magazines.

Since the HK416 closely resembles that of the AR-15 Platform, with only minor differences in certain areas, ergonomically they are close enough as a training tool to represent the AR-15 in that role. I find that the HK416 Enhanced Red Gun is a huge improvement of what I trained with years ago where the M4A1 Redguns had fixed carry handles and no rails at the foreend. With a flat top and rails, you can attach an optic and weapon light or laser if desired. That just adds to more realism into the training session.

I threw on a spare Primary Arms/Holosun ACSS Micro with Reptilia DOT Mount on the flat top.

Red Guns in the long gun form are useful for initial movement drills for active shooter or CQB training events where everyone can focus on moving safely with inert training tools. There is absolutely no mistaking a Red Gun as a training tool whereas blue masking tape on a barrel and magazines may not be seen in certain lighting conditions. While those in the early stages of training can get used to the movement in tight, dynamic drills, the Red Guns can take the beatings from hitting door jams, walls and other obstacles and saving the live firearm from unnecessary abuse, not that they can’t handle the abuse, but why expose them to it when live fire or simulations aren’t in play?

Weapon retention drills also are just as important with a rifle as they are with a pistol. Like their pistol counterparts, it isn’t practiced much and probably less by a long shot in comparison. The Red Gun will be much more forgiving than a full weighted rifle if there is any accidental contact during a drill, reducing and minimizing injuries if that happens.

With the HK416 Enhanced Red Gun, I was able to practice my emergency and tactical reloads in my living room with full confidence that I will not have any chance of a negligent discharge as there is no possibility of clambering a round in a mostly solid piece of polymer.

Practice those Tactical Reloads!

Since the Enhanced version has the capability of inserting and dumping a magazine, it can be an effective tool in teaching a total newcomer with the AR-15 Platform on how to safely handle and load and unload it before moving onto a empty live firearm.

There is an option for a collapsible stock on other Red Gun M4A1 and I wish the HK416 Enhanced Red Gun had one since I have short arms and an adjustable length of pull would be appreciated but I understand that it increases the cost of the Red Gun.

Overall, the quality, fit and finsh of the sample ASP HK416 Enhanced Red Gun is excellent. The addition of the magazine drop feature as well as the rails puts it on another level when compared to the previous Red Guns. It gives the end user more ways to practice safely than before. Red Guns are the best tool to stand in place of real firearms in the training environment where sims or live fire is not needed. ASP did a great job in improving upon their line of Red Guns to make them even more versatile and practical.
