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.

  • edward said:

    We fired over 300 rds on the range from 15 to 100 yards. The Black Hills 556 and 223 is absolutely the finest rifle ammo our agency ever used. It will save your life if ever in a gun battle with bad guys.

  • NW said:

    Great experience. Hard to find ammo at good prices. Customer service was excellent with an issue we had to resolve with my order. Top shelf all the way around.

  • Zachary said:

    Works great out of my 11.5" bcm and my 18" 1:8 twist barrel consistent groups and no issues.

  • CM said:

    First time customer (of website and vendor), was really happy with their value, the way they shot and the quick arrival!

  • Boostrapbill said:

    I would buy again. I check ammo.com first for everything I need.

  • Defend said:

    Ammo is as advertised. Good ammo

  • Dave said:

    Good quality

  • Brian said:

    No problems feeding, cycling or firing. Not a one. 500 rounds in and buying more. AR-15 platform.

  • Bang bang said:

    Great ammo, great price

  • CDH said:

    Shipped quickly Haven't had a chance to send some down range. But sure they'll be fine

  • 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.

  • Glen D said:

    Overall no jams after firing 120 rounds, good ammo at a fantasic price . perfect for the range good quality ammo, federal delivers!

  • patrick said:

    Ok

  • Sike said:

    For relatively cheap ammo Works fairly well only had 1 misfire out of about 200 just had a little too much lacquer on it

  • donald said:

    good ammo good price fast shipping will buy more and tell my friends..i do recommend

  • Dr. O. said:

    This ammo was a great value. And performed well. Not a single jam. Very consistent

  • TedG said:

    Fired about 100 rounds. No misfeeds, no duds, no significant accuracy loss over green-tips at 100yrds. I did notice that the spent casings actually eject a little differently (more to the rear and in a tighter grouping). This is actually nice for me because, when I fire federals, about 1/2 of the brass flies out the window of my shooting hut while the Wolf "brass" piles up in a neat little spot next to me on the inside of the hut. The price is right - highly recommended for plinking!

  • myob said:

    good ammo

  • Rick said:

    Price was right, delivery was quick, Fed and ejected with no problems.

  • Jimbillyjoebob said:

    You have to keep your AR clean no matter what ammo you feed it. I would not use this ammo for hunting if I had better available, but if you're going to be humming through 300+ rounds on an afternoon, it's hard to beat. Very rare misfeeds.
