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.

  • Matthew said:

    The Ammo is great, but the one hitch in my "Giddy-up" is: The ammo on the website reads "FMJ-BT", but what showed up at my door was regular FMJ. I'll still shoot it, but I'll be wary, before I order from here.

  • Kim said:

    Good stuff

  • Joel said:

    This round was very consistent, very clean. I don't think you can do better for price in a brass cased round. Shooting in a Daniel Defense m4v11 they were flawless. Definitely ordering more.

  • Shooter magavin said:

    Have bought this ammo a couple of time and could not be happier

  • ammosmurff said:

    I've shot PMC ammo for years on the range, for .223, .45acp & 9mm, never had a misfire or failure to feed on any of my guns. Korean ammo is the only foreign ammo I'll buy!

  • J A said:

    I have not shot any of this ammo as of yet because it is down the line in my rotation. But I was comfortable purchasing PMC ammo as I've never had any bad ammo from the company. The price was right at the time so it was a good buy for me. I look forward to purchasing ammo from your site again, thank you...

  • Dave said:

    Very good ammo for the money! Reliable and accurate. Can't ask for anything more than that.

  • dkmatthews said:

    There's no doubting the quality of PMC Bronze. It's super reliable in every firearm. Thanks for a good deal on the case of ammo.

  • chris said:

    I have a remington Model 700sps varmint 223. with a bull barrel, n added a bipod, and a Barska 4-14 x 40 scope. i picked up a fiew boxes of the pmc bronze boat tail ammo in 55 grain simply because they wer only 7.25 for a box of 20. i was realy surprised on how consistant they wer. i placed 18 outa 20 rounds in a 3 inch circle at 150 yds. with a slight breeze. over all im realy pleased with this product, and will continue to use, an recommend this ammo.

    500 rounds deep and havent had a single issue feeding, ejecting, firing, nothing. this was the most affordable option at the time and it did what it was supposed to do. shipping was also pretty quick and easy.

  • Rusty said:

    Everything worked well. No misfires, no feeding issues.

  • Chief Gorilla said:

    Very tough exterior bag similar to some issue ammo during deployments. I see no issues that concern me. It saved me from doing my own storage prep.

  • Chief said:

    Performed well. Lots of rounds and no issues!!
