1. Brownell’s AR-15 30RD Magazine Review

Brownells AR-15 30RD Magazine CS

Brownell’s very own magazine is able to accommodate the .223 Remington as well as 5.56mm NATO AR-15 cartridges. For your information, these cartridges are very popular and well-known to be paired with the AR-15 rifle to the point that you can even interchange them, according to your preference. However, it is best to refer to the instruction manual before doing so.

In terms of capacity, this product holds up to 30 rounds altogether, 30 rounds is a rather common number/capacity and if you notice, most mags offer 30 rounds. However, if you’re going competition shooting or so, I suggest you get a mag with higher rounds for convenient shooting. Equipped with a rugged military gray finish, this model is made from aluminum. Though most people prefer polymer mags, the aluminum ones are good to go as well.

However, you can give it a little drop test before proceeding to shoot with it. The test is rather simple, whereby you need to drop the magazine to the ground, from a certain height. If it leads to severe feed lip deformation, then it’s a bad sign indicating that it will not be able to handle the powerful recoil from your weapon. Furthermore, all components are manufactured under strict ISO quality control standards and are made of mil-spec materials.

In terms of construction, it is said to be rather solid and sturdy because the magazine is heat treated and comes with a welded aluminum body. On top of that, the body is hard anodized to provide excellent corrosion resistance, then applied with a tough-dry lube coating which comes in handy to eliminate any need for additional lubricant, which would sooner or later attract sand, dirt and dust.

Apart from that, this updated material and design of this product that holds the 30 round mag have also been adapted and incorporated to Brownell’s very own straight bodied 20-round model. The follower on the other hand is made from the latest military-type glass-fiber reinforced composite material which further guarantees excellent and flawless feeding, even under the harshest tactical conditions.

Just so you know, having a solid follower is essential so that they properly load the ammo into the breach of the barrel. The high-lubricity, dry-lube coated silicon spring is also corrosion resistant, in fact it is certified to a total of 500 hour salt spray standards as well as is less prone to spring ‘set’, therefore providing good pressure to the ammo, so they rise with a fair amount of force to hit the feed lip.

Key Features:

  • Heat-treated, welded aluminum body
  • Glass-fiber reinforced composite follower
  • Dry lube-coated silicon spring
  • Hardcoat anodized

2. Lancer System L5AWM Translucent Mags

Lancer System L5AWM Translucent Mags

Similar to the Brownell product above, the Lancer System magazine also accommodates the .223 Remington and 5.56mm NATO, AR-15 ammunition. It also holds 30 rounds (capacity) altogether and is made from solid polymer construction. The polymer material is said to be extra durable compared to using a metal mag, based on the drop test results conducted.

Apart from that, it comes with a total of 5 magazines, nevertheless it is also available as a single product. If you’re a frequent shooter or buying in a group, it is advisable to get them in bulks because it would be a great investment in the long run. Buying in bulks also contributes to cheaper price as it is slightly cheaper than original price itself.

The unique part is that it is equipped with a clear and translucent finish so you are able to view your ammunition inside the mag. In addition to that, this lightweight molded polymer mag stands up to extreme conditions and rough handling in a tactical operation, including heat as well as impact of sustained full-auto fire. In fact, it is tested to withstand extreme temperatures ranging from -50 F to 180 F. Also, it is said to withstand a 5 foot drop onto concrete (with fully loaded cartridges) miraculously without any impairment or malfunctions.

Not only that, the non-reflective exterior is equipped with molded-in ridges together with an improved texturing design which comes in handy to increase the structural strength and ensure a solid grasping surface. On top of that, the hard polymer base plate contributes to a positive gripping surface so you are able to extract the mag from tight-fitting pouches and remove them with ease, for cleaning and disassembly.

Lancer System’s magazine features the AWM (Advanced Warfighter Magazines) which fills in the gap between the current metal and polymer mag designs, for a more reliable product. This 30 round model is able to accommodate pouches for the standard USGI-spec mags. Fixing it to the lower receiver of your AR-15 is rather simple, you just have to load it to the full capacity and insert it into the weapon with the bolt closed.

Moreover, the feed lips come with a permanently attached and wrap-around feature. That being said, the feed lips are made from one piece of precision formed, hardened steel that is PTFE coated to enhance its resistance to corrosion.

Other than for improving corrosion resistance, this PTFE coated feed lips promotes smooth ammunition movement without any hint of deformation, when the fully loaded magazine is stored for a long time. Also, constant-radius body curve feature as well as anti-tilt follower feature comes in handy to ensure smooth and snag-free feeding, without jamming.

Key Features:

  • AWM feature
  • Molded polymer mags
  • PTFE coated feed lips
  • Hard polymer base plate
  • Anti-tilt follower
  • Constant radius body curve

Moving on, the spring is made from long life USGI-spec stainless steel which further contributes to its rust-resistant characteristics.

My favourite part about this PMAG Gen 3 model is the pen dot matrix feature which allows you to mark different ID on your magazine with the pen provided. The pen dot matrix idea is rather innovative because it resists handling wear, in the long run. In addition to that, its pop-off dust cover reduces the intrusion of dust and debris into the mag hence making it easy to clean.

Speaking about cleaning, you need not have any tools to disassemble the magazine in order to clean it. In fact, you can do so by simply using your hands therefore contributing to your added convenience.

The PMAG D-60 model is a lightweight, durable and highly reliable product. It holds a total of 60 rounds altogether which comes in handy if you’re a competition or avid shooter. This is because rather than the conventional 30 rounds, you’ll be having an extra 30 rounds to shoot at, without having to replace or reload them.

In other words, with larger capacity (double) than the previous PMAGs, the PMAG D-60 allows the shooter with 60 rounds of ammunition. Hence, it effectively allows the same round count as 2 standard 30-round mags without requiring critical reload. Since it accommodates 60 rounds altogether, you can imagine a bigger and distinct shape of the magazine.

Compared to the other models, this product features a unique drum configuration to compensate for the extra 30 rounds. Rather than making it bigger in terms of height, Magpul decided to give it a drum-like base to make sure the height is manageable as well as to allow prone firing and easier storage, thus improving your shooting experience.

Understanding the Magazine

A magazine is referred to as an ammo storage or feeding device within a firearm. There are two styles of magazines, with the first one being the removable mag and the latter being a fixed mag. Apart from that, it consists of a few parts altogether which are the spring, feed lip, spring follower, body and base.

The mag’s follower functions to hold the ammunition in place, so that they are able to load into the barrel breach properly, with maximum ease. The feed lip on the other hand is usually located at the top of the magazine, whereby it prevents the cartridge from falling out of the magazine until it is pushed forward and into the breach, via the bolt.

Moving on to the spring, it ensures good pressure on the cartridges, therefore allowing them to rise with enough force to hit the feed lip. Moreover, you need to make sure that the magazine has good tilt and balance. If the follower tilts one way or another, the rifle might get jammed in the midst of feeding.

magazine feed lip

Apart from that, this AR-15 mag comes in all shapes and sizes, depending on the number of round/capacity that it has to accommodate. For instance, some are able to accommodate as low as 10 or 20 or as high as 60 rounds in the magazine chamber. However, the most common capacity is 30 rounds. So, it can be said that the size of the mag increases when the number of rounds increases so it can hold all of the intended rounds securely.

There are also 2 distinct feed lip designs which are the single-feed and double-feed magazine design. For single-feed one, the top cartridge touches both lips and is mostly used in single-column box magazines meanwhile for the double-lip type, its wider set of lips results in the second cartridge in line forcing the top one against one lip. That being said, the double-feed design is proven to have good resistance against jamming.

Now, let’s look at the difference between the fixed and detachable magazine. The fixed type is also known as an internal, integral box. It is built into the firearm therefore, not easily removable. Often utilized in bolt-action rifles, the integral box is charged through the action, with only one round at a time.  Conversely, the detachable box is a basically a self-contained device whereby you can load or unload it to the host firearm.

For your information, they are attached using a slot in the lower receiver of the AR-15. Since it’s removable, you can detach it with ease, and replace it with another. One of the plus point of having this type of magazine is that it speeds up the reloading process as well as provides you with quick access to the ammo. Moving on, the common confusion a lot of people have is differentiating a magazine and a clip. So, let me clear your doubts.

Clip vs Magazine

The rectangular box-like device is the magazine. It holds cartridges for your firearm and slides from the bottom of your rifle. In other words, it holds shells under spring pressure so it is well-prepared for the feeding process, in which the ammunition is fed into the firearm’s chamber. Some of the popular magazines include the tubular, drum, box as well as rotary ones.

Meanwhile, the clip comes without a spring. It doesn’t feed the shells directly into the chamber, instead it places the cartridges in the correct order to charge the magazine. For example, the stripper clips ensures that the rounds are stripped into the magazine while the others are usually fed together with the shells into the mag. After all rounds are fired, the clip is ejected/ released from the firearm. In short, the process goes like this; the clip feeds the magazine and the magazine feeds the firearm during shooting.


In a nutshell, a magazine is an essential part of the firearm because it stores your cartridge to be fed into the chamber followed by the barrel, in order to fire a shot. Hence why, you should choose the right product which is solid and strong enough to withstand strong impact as well as have an excellent corrosion resistance.

A good magazine will result in an accurate and good overall shooting performance. Thus, I hope my review assists you in making the right choice. Happy shooting!
