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.

    Very pleased with this ammo that I bought It looks to be well put together every round shot as it should I didn't have any jamming issues everything fed the way it should Good ammo I'll be buying it again.

  • DAVID said:

    Excellent service from when I placed my order to when I received it. I'll be ordering here from now on.

  • Roge said:

    Amazing price For Some ammo!!! Without a doubt in my mind!!

  • CDH said:

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

  • Shad said:

    Great Ammo; Pricey

  • J bone said:

    Same ammo as all the rest, most I've ever paid .

  • Zachary said:

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

  • Voltron said:

    Good product, great price, packaged well, arrived on time, shoots well, will purchase again Works fine in my suppressed DDM4 V7

  • Jimmy Crack Corn said:

    Seemed good once I had ar sighted in red dot at 40yds. New ar prolly like 20rds (mostly newbie errors well say). once zeroed blew throught 200rds no hiccups n could rapid fire on target well unless bullet accounted for my terrible aim?

  • Mike said:

    Best prices came within a few days of ordering. Very happy, would recommend and use again and again.

  • Michael said:

    The price is one of lowest price per bullet I've found. The quality and performance are great. I've shot over 200 rounds of these and not a single misfire or dud. You can't go wrong with these for your AR

  • Eric said:

    I bought the PMC 55.6 ammo and I have had issues every time I am at the range with at least 1 to 3 misfires per 30 round clip. I am shooting with a BCM 16 inch Rifle that was just bought a few months ago and only has about 200 rounds through it. I took it apart and cleaned the rifle and still have misfires and have used multiple different clips.

  • Hamb0ne10 said:

    Never had a problem with pmc ammo.

  • J said:

    Quality ammunition

  • Josh said:

    Had two days of rifle training scheduled with a paid group. Both training classes cost around $1,000 for both days so the issue is when you pay for training you need ammo that will perform so that way you don't have to worry about missing out on what you've already paid for and this ammo did that! Not one misfire out of every round of the thousand purchased. Nice to be able to still find quality products out here.

  • Kyle said:

    I've used about 200 rounds and it works flawlessly.

  • Just a guy ~ said:

    This is my favorite 5.56 cartridge, hands down. Every component is top quality & PMC doesn’t cut corners. I’ve shot them all and this is the most accurate & reliable 5.56 factory cartridge. I prefer the 193 - wish it was 62 or 69 grains… The brass is excellent & should absolutely be kept for reloads (I safely get 3 reloads per). A small shop by me sells it for $8.99 a box in 2023… That’s a steal. Have fun & remember that firearms safety is 100% on us.

  • Ron said:

    I like PMC Ammo the 5.56X45mmNato is what I shoot. Great for range, self protection, The reason I purchased this ammo is because of who makes this.

  • Kenneth said:

    couldnt find ammo locally so i checked the net fully expecting 2-3 wks for delivery. ordered early on a saturday morning. was on my door step monday. impressive

  • txweld said:

    All good

  • Runner said:

    PMC is a very reliable ammunition , I would not hesitate to use if for self defense. It shot well and now that I have shot it and used it all, I`ll need to order more. BTW , I use PMC in my handgun for home protection and it is as good as it gets and the 5.56x45 is as great .

  • MM said:

    I shot about 200 rounds through my brand new SIG716. The very first 3-4 rounds wouldn't feed perfectly, but I attribute this to the brand spanking new equipment. After that, rifle and ammo performed flawlessly. Not a single issue with feeding, cycling, firing, etc. At 150 yards, I had all shots within about 2-3 inches using a cheap scope and no rest. Great product and especially GREAT SERVICE! Thank you guys!!!

  • D said:

    Great customer service, placed the order last friday fully expecting not to get the order with all that is going on, you won't find a better company to deal with, as for the Ammo, top notch perfect for my use.

  • CowwFace said:

    I got this for taking to the range, went through about 100 rounds and zero duds. works perfectly in 2 AR's. We were using Red-Dot scopes, and hit what we were aiming at about 100 yrds away. I would highly recommend this ammo.

    I've used Winchester rounds in other calibers and never been disappointed by them, and I can say the same for these 5.56 rounds. Excellent training rounds, good pricing, and I've had no issues with the first 450 rounds I've used so far.

  • D. said:

  • Jacob said:

    The rounds were dirty, with some having excess powder or some kind of processing oil/grease on them. A few boxes had 18/19 rounds in them. Worked well in my rifle after 500 rounds so far and were a good price.
