Why Brass Catchers Are Important

A brass catcher can be about more than just convenience. Some shooting ranges require you to pick up any brass, and it is also a courtesy to your fellow shooters. Hot brass ejected with force from the gun can strike people standing beside you; a brass catcher can prevent that from happening. For military and tactical users, firing from enclosed places like vehicles and aircraft can make flying brass a hazard.

Rather than picking up after yourself, a brass catcher does the work for you. Gun owners who like to reload will love brass catchers as they will never lose brass again. Hunters know from experience that it is virtually impossible to find spent brass at night in the undergrowth, so a brass catcher will be very convenient. Brass can also be recycled and you can get paid for collecting and selling brass to recyclers.

What to Look For in a Brass Catcher

When you’re looking for a good brass catcher to purchase, the key factors to take into account are installation, reliability, non-interference and price. Let’s break these down a bit further.

Easy Installation

The catcher should be easy to put on and remove, both for stowing your gun and to make it convenient to use when at the range or in the field.

Small Attachment Points

The less space the catcher takes up, the less it will interfere with your other accessories and be more natural to use.

Heat Resistance

On a hot day, and firing for an extended period, the brass gets hot enough to melt nylon mesh and less-durable containers. Avoid such materials when you’re looking a brass catcher.


A good catcher will be designed to avoid bounce-backs and clogs in the ejection path.

Non-interference with Operation

The catcher needs to stay out of your way while manipulating the weapon.


Finally, the price should give you real value when compared to other brands out there.

Review of the Best AR-15 Brass Catchers

Let’s look at some of the best AR-15 brass catchers out there based on the factors we outlined above. These catchers will not just fit your gun perfectly, they’ll also perform their function flawlessly and prevent jams during ejection. Most importantly they’ll stay out of your way while you’re shooting.

Best Overall:
 Caldwell Shooting Supplies Brass Catcher


  • Very heat resistant
  • Quickly attaches to most AR-15 rifles
  • Excellent for hunting and target shooting
  • Spacious, can catch many brass casings
  • Prevents scrounging for brass, making reloading easier


  • Some other mounting issues may arise
  • Adjusting the bag might be a little tough
  • May not be compatible with some scope mounts

What Recent Buyers Report

Most of the new buyers were quite satisfied with the brass catchers. They were able to fit all their discarded brass in the catcher itself without having to look for them on the ground. One user said that the bag stays cool regardless of how many brass casings stay warm after ejection.

Why it Stands Out to Us

This brass catcher is made with a material that doesn’t melt or give in to the heat of a recently discarded brass casing. Not only that, you have enough space to work with so you’ll have a full bag by the time you’re done with your range session. Plus, with the aluminum clamp included it will fit most Picatinny rails or side rails. Never again will you have to look for discarded rounds on the ground if you usually tend to reload them manually.

This brass catcher can be fitted onto your AR-15’s Picatinny rail, with cases being ejected straight into a collection bag for disposal or reloading. The catcher is made of heat-resistant mesh and holds up to 100 .223 cases. A zipper at the bottom of the mesh bag makes emptying quick and easy.

The AR-15 Pic Rail Brass Catcher has an aluminum clamp and steel wire frame that are fully adjustable to work with almost any rail and optic configuration. The bag will not interfere with bolt function or cycling. It is also compatible with most .308 AR-pattern rifles

Its lightweight quality construction makes it a great option. However, if you’re going through the woods or in tight spaces, it can be difficult to handle because the bag doesn’t collapse.

Who Will Use This Most

This will be used by target shooters at the range. Especially if you’re looking for a brass catcher that will be a reloader’s dream. When you have empty casings, they just might be good enough for another reload or two. So if you want to keep your casings, you’ll need a catcher to hold them all together. This one might just take the cake for a few good reasons.

Bottom Line

The Caldwell Shooting Supplies Brass Catcher will likely be your best friend out on the range. Once you have all your discarded brass gathered up, you’ll save yourself extra cash rather than try to purchase a new box of AR-15 rounds.

 3 BUCC Inc. AR-15/M16 Brass-Savr Brass Catcher


  • Excellent for reloaders
  • Extremely heat resistant
  • Installs easily on most rifles
  • Great for multiple applications.
  • Spacious to hold a lot of brass


  • Lacks a quick on/off feature
  • Bases may feel cheap in quality
  • Pricey for some budget shoppers

What Recent Buyers Report

New buyers were happy to report that this brass catcher was a pretty good size. They said it wasn’t too big or small, but the capacity was quite right for catching discarded brass casings. One user said that he was able to keep his used brass for reloading purposes. Plus, the bag stayed cool and didn’t ruin the material.

Why it Stands Out to Us

This catcher is made from some seriously durable material. Plus it’s perfect to collect so many brass casings in a single session at the range or if you’re out and about hunting. Either way, you’re going to need one of these if you’re tired of spending a ton of money on ammo.

This catcher consists of a cotton-poly bag, supported by a steel frame. It has a capacity of 70 rounds of .223 brass and has an easy-open bottom to unload quickly. It comes in separate models to fit carry handle and flattop AR-style rifles. The polymer mount comes in black with a matte finish. The catcher is 4¼" (10.8cm) wide, 3½" (9cm) long, and 7¼" (18.4cm) deep.

A good value, this bag is easy to install, safe and tough. However, some shooters have had problems with it overheating since it allows for little ventilation.

Who Will Use This Most

This will be best used by hunters, target shooters, and even some competitive shooters. No matter what, this catcher allows you to save all your discarded rounds so you can use them again and again.

Bottom Line

The 3 Bucc Inc. AR-15/M16 Brass-Savr Brass Catcher might be right up your alley if you want something that will allow you to keep your brass and use them whenever you need them again. If you like reloading your AR-15 rounds and want to keep them around for a long time, then this brass catcher could be exactly the kind of catcher you’re looking for.

Best for the Money:
Tacstar Brass Catcher


  • Easy to detach
  • Easy to mount and attach
  • Resistant to heat
  • Spacious. holds a lot of discarded brass
  • Does a great job fitting on most Picatinny rails


  • None

What Recent Buyers Report

New buyers were quite happy with this brass catcher. Not only were they satisfied with it as a whole, but they were also quite impressed with the quick attach and detach feature. One user said that he was able to use it for quick brass storage after emptying a few of his extra magazines. He added that the casings were good enough to be reloaded and reused multiple times.

Why it Stands Out to Us

This brass catcher might be one of the best in the business for its ability to attach itself to Picatinny rails. We also love it when the catcher can attach and detach in a matter of seconds. Especially when you’re far from done with your day at the range and still have plenty of rounds to go through. Plus, you can empty them into a large bucket and repeat the process until you’ve had enough.

The TacStar AR-15 Brass Catcher is made from heat-resistant Nylon and holds up to 120 .223 Rem cases. It can be attached to the rifle using a Picatinny-rail mounting apparatus that works on any flattop AR-15 and it won’t interfere with optics or other accessories.

After shooting, the bag can be removed from the mount without undoing the rail assembly, enabling easy cleanup. It will work with nearly any AR-15 on the market, regardless of caliber or setup.

Who Will Use This Most

This will mostly be used by those who spend time at the range for casual target shooting or tuning up for upcoming shooting competitions. No matter which application is the best fit for you, you’ll know that this brass catcher will be reliable each time you use it. If you want something that is built to last and will prevent you from having to spend a lot of time looking for your discarded rounds.

Bottom Line

The TacStar Brass Catcher is one of the only brass catchers on the market that can work well with Picatinny rails and catch as many brass rounds as possible. You probably won’t need a brass catcher other than this if you want something reliable, can hold a lot of rounds and can give you quick attachment and detachment ability.

4. E&L Manufacturing, Inc. - Brass Catcher

This brass catcher from E&L is made from polymer and uses a snap-on technique to fit on your AR-15’s receiver. It has a capacity of a minimum of 60 expended rounds. This catcher won’t interfere with any moving parts on the firearm.

The strong points of this catcher are that it’s lightweight, quality construction that’s easy to adjust and won’t jam your gun. However, it may take some modification to your scope mount to install it. And if you’re a left-handed shooter, you’re out of luck, since it’s not reversible. It’s also smaller than other catchers.

Pros and Cons of Brass Catchers

Every addition to your weapon has some pros and cons associated with it. Here, we’ll take a look at some of those associated with brass catchers.


Easy Collection

Many people like to reload their ammunition rather than buying new ones, especially for calibers which are expensive and difficult to find (6.5 Grendel, .458 SOCOM, etc.) If you are hunting in the woods or shooting in an open field, you know how difficult it is to keep track of every spent cartridge. A brass catcher makes it easy to collect spent cases without any effort, whatsoever.

Cleaner Workspace

Some ranges require you to pick up spent cases. Plus, littering cases after you’re done shooting is not a good idea. Morally or logically. So a brass catcher lets you keep the shooting space clean.

Reduces Imminent Accidents

Flying brass can be a problem for people standing beside you. Since it is hot and flies at a good velocity, it has the potential of injuring anyone nearby. Plus, if there’s some piece of machinery or equipment with crevices and openings, it can catch these cases and result in accidents. A brass catcher eliminates all such possibilities. 

Easy to Use

A brass catcher is the easiest and most intelligent method of collecting spent cases. These catchers are lightweight and easy to carry, store, and use. Installing a brass catcher takes less than 10 seconds. 


Extra Weight

A brass catcher is lightweight, but it still adds some weight to your rifle. Plus, with every round shot, it increases in weight. So that is a possible disadvantage of using a brass catcher.

Intrusion in Operation

As a brass catcher collects casings and increases its weight, it results in a slight shifting of balance to the port side, so you have to maintain equilibrium. Plus, it will require some practice to use a catcher since it interferes with your shooting stance. 

Picking up the Brass

Even if you’re not using a brass catcher, it is still a good habit to pick up your spent cases that reach the ground so that you are not littering. Even if you’re not reloading or recycling, it is the environmentally-friendly thing to pick up after yourself if you’re outdoors or hunting.

At some ranges, you may not be allowed to pick up brass that is not marked as your own, so do check the policies of your shooting club. If you find that it’s too much trouble bending over to pick up your spent brass, check out the Caldwell Shooting Supplies Brass Retriever.


If you’ve ever tried collecting your spent casings by hand after a day of practice shooting, you may be surprised what a difference a good brass catcher can make.

Cleaning up after yourself is a good habit for a shooter, and there are ways to recycle or reload your cases and save a few dollars. Keep in mind the qualities of a good brass catcher when purchasing and you’ll be all set.
