The Brass Goat is a brass catcher made for AR-platform rifles. It snaps right onto the magwell of your lower receiver; no tools, no screws, no hassle.
As you shoot, it catches your spent brass so you don't have to chase it across the range. It comes as a 2-piece unit; a deflector and a hopper. You can use both pieces together or just the deflector by itself.
Magwell Mounts is the original designer, patent holder, and manufacturer of the Brass Goat. We proudly manufacture and assemble all of our products in the USA.
The BG15 is the Brass Goat version made for AR-15 platform rifles, designed to deflect and catch your fired brass.
The BG15 works with standard mil-spec AR-15 lower receivers with right-hand ejection. If your AR-15 was built by a major manufacturer and you haven't modified the lower, it will most likely fit. Use the Compatibility Checker on our website to confirm or contact us and we'll help you out.
A mil-spec lower receiver is the most common type used on AR-15 rifles. Most factory-built AR-15s from well-known brands use a mil-spec dimension lower receiver. If you're not sure, the Compatibility Checker on our site can help, or just reach out to us directly.
No, the Brass Goat is designed for right-hand ejection only. We do not currently offer a left-handed version.
The BG15 fits most mil-spec AR-15 lowers, including rifles from brands like Anderson, Ruger, Daniel Defense, POF, Windham Armory, Black Rain Ordnance, Savage Arms, and many others. It is NOT compatible with rifles that have a non-mil-spec or flared magwell (such as the KE Arms KP-15 or Silencer Co lowers), or with side-charging uppers. If you're not sure about your specific rifle, use the Compatibility Checker on our website or send us a message at admin@magwellmounts.com.
Yes, as long as your AR pistol has a mil-spec lower receiver with right-hand ejection.
The standard BG15 does NOT fit the M&P 15-22 because it has a different magwell size. We make a dedicated version specifically for the M&P 15-22; check out the BG15-22 on our website.
The BG10 is the Brass Goat version made for AR-10 platform rifles. It works the same way as the BG15 but is sized for the larger AR-10 magwell. It comes with five removable shims to fit a wide range of AR-10 lowers from different brands.
The BG10 works with a variety of AR10 firearm manufacturers and models. The BG10 includes (5) removable and reusable shims to assure maximum flexibility.
AR-10 rifles come from many different manufacturers, and magwell sizes can vary slightly between brands. The five included shims let you dial in a snug, secure fit no matter which brand of AR-10 lower you have. A shim selection guide is available on our website.
We make a dedicated version for the Ruger SFAR — check out the BG10-RSF on our website.
Because the Brass Goat attaches to the magwell on the lower receiver, it won't interfere with any optics, red dots, EOTech sights, magnifiers, or other accessories mounted on your upper.
Some oversized scope mounting hardware may interfere, but modifications can be made in many cases. Contact us for more information on modifications.
No, Brass Goat is not compatible with drum magazines.
Yes, it is compatible with 10-round magazines. Keep in mind the standard hopper is sized similarly to a 30-round magazine. If you want a more compact option for use with shorter magazines, check out the mini-hopper (BG15-M).
Most likely not. If you have a side-charging upper, send us a photo at admin@brassgoat.com and we can take a closer look at your specific setup.
The Brass Goat is only made for AR-15 and AR-10 platform rifles. We don't make versions for AK-47s, Ruger Mini-14s, Hi-Point carbines, bolt-action rifles, or other platforms at this time.
No, Brass Goat will not interfere with the mag release button.
When properly attached the right side mounting tab will engage by the trigger guard pocket, below the magazine release button.
Brass Goat is compatible with any cartridge for AR-15 and AR-10 platform firearms.
Examples include:
The BG15 attaches to the magwell of the lower receiver, not the caliber-specific upper. However, 9mm AR lowers often have different magwell dimensions (especially those using Glock-style magazines), so fit is not guaranteed. Use the Compatibility Checker or contact us to confirm.
The standard hopper is about the same size as a 30-round magazine. If that feels too big for your setup, the mini-hopper (BG15-M) is a smaller, lower-profile option that many shooters prefer for bench shooting.

Yes. The Brass Goat comes with a manufacturer's warranty. View full warranty details.
The Brass Goat is made from tough ABS resin, so cleanup is easy. Pop it off, disassemble the two pieces, and wipe it down. Warm water and mild soap work fine if needed. Always follow safe firearm-handling rules before removing it from your gun.
In testing, we haven't seen any finish damage. To be safe, we recommend applying a small amount of Rem Oil to the magwell before snapping the Brass Goat on and off. This protects the finish and makes attaching and removing it even easier.
Yes, we do offer a dealer program and are always looking to add new dealers to our network within the U.S. and abroad. Apply to become a dealer.
