Overview of Bulk AR-15 Ammo

The AR-15 is commonly chambered for a variety of different cartridges. The 5.56x45 is the most common (noting that 5.56 firearms can also safely fire 223 Rem ammunition). But if 5.56/223 isn't the best AR-15 caliber to suit your needs, don't worry! We carry a wide selection of bulk AR-15 ammo in your favorite caliber.

How Will Your Bulk AR-15 Ammo Be Delivered?

Your AR-15 ammo purchase will be shipped straight to your door in a discreet, unmarked package.

Benefits of Buying Bulk Ammo?

  1. You save more money: Probably the biggest reason to buy bulk AR-15 ammo is the cost savings. You can save upward of 10¢ per round!
  2. You're ready for the range: If there's one thing that 2020 taught us, it's that supply chains are fragile. Bulk rifle ammo purchases ensure you'll always be locked and loaded.
  3. You reduce the hassle of reordering: With bulk purchases, you reduce the frequency of reorders, ensuring you always have enough ammo on hand for any occasion.
  4. You shoot more consistently: Buying in bulk ensures a consistent supply of the same ammo, which can improve accuracy and performance by eliminating variations across lots.
  5. You'll be prepared for anything: Whether it's a spontaneous range day or an emergency, having a bulk supply means you're ready for unexpected needs.
  6. You support some great organizations: For every purchase you make at Ammo.com, we'll make a donation to a freedom-loving nonprofit organization. See who we support here!

How to Choose the Right Bulk AR-15 Ammo

When purchasing bulk AR-15 ammo, there are a few precautions one must take. The most significant is ordering the correct cartridge. Some AR-15s only accept 223 Rem, while others also safely fire 5.56 NATO. Many others are chambered for 22 LR, 300 AAC Blackout, 350 Legend, or 450 Bushmaster, as well as pistol calibers such as 9mm and 40 S&W.

Once you've established which cartridge is safe to fire in your AR-15, it's time to decide if you want to load up a bunch of cheap plinking ammo or higher-quality competition, hunting, or defense rounds. Another consideration is your budget. How much are you willing to spend on ammo? Price will determine the quality and number of rounds you can purchase. We recommend buying small quantities of several different brands and loads to test which performs best in your rifle, and then stocking up on your favorite.
