Overview of 5.56x45 Ammo
Eugene Stoner developed the 5.56 NATO in the 1950s for the AR-15 platform, officially adopted by the U.S. Military in 1963 as the standard infantry cartridge. Its lightweight, high-velocity rounds allowed soldiers to carry more ammo without sacrificing effective range or accuracy.
Today, it's one of the most popular cartridges because of its low recoil, cost, and excellent accuracy, even in the hands of a relatively new shooter.
During the Cold War, the Soviet Union developed their own lightweight intermediate cartridge in response to the 5.56 NATO. The 5.45x39mm was designed with similar goals in mind: reduced recoil, higher capacity, and improved accuracy.

Joe said:
I am very pleased with their service, quick delivery and product. I have not experienced any issue with their product at the range. I highly recommend this website for all the above mentioned reasons.

I was glad to find that Ammo.com had plenty of stock of this ammo. I searched the net of a lot of places, their prices are very competitive.

twolazy said:
I have not shot any of this batch or the batch prior, I haven’t even opened the boxes. I’m in high hopes I never have to open these boxes. I’ve used Federal 5.56 before and it is good stuff. Price is stiff, not as stiff as some I’ve seen. But then everything gun related is more expensive, isn’t it. Get it while the getting is good.
-
Doc said:
I guess a shortage in the ammo supply has driven the price up, as I found your ammo to be a bit more expensive than I had anticipated.. Regardless, the delivery time was exceptional & the ammo itself came in good condition and preformed well.
-
Tommy said:
I have already recommended it, that being said, it is a bit pricey. But considering that there is such a shortage, I was happy to have it. I get a small disability check once a month, so, I'll have to save more money.
-
CJ said:
The order was handled quickly and efficiently. I would recommend Ammo.com to anyone who has stood in line trying to find ammo.

Adam said:

Nice to know where to locate ammo after this BS of low production and high demand.

Joe-we-had-a-baby-it's-a-boy said:
Ammo was well packed, but the tins came in a bit banged up. Ammo was clean in good shape but stripper clips showed moisture damage with minor rust making it hard to load with the speed loader. The cost was deffently high and go figure right after I ordered I found 1000rnds of loose pack 62gr lake city for the same price as one tin of 420rnds, but finding 556 ammo these days is deffently a gamble of finding it and its price! Hopefully all this Bull will be over soon!

good clean ammo and a great overall value

This ammo package is over twice as expensive as it should be. If you don't reload your own .223 just go with Wolf...

murdock said:
62 grain shoots just fine. no jams. but that old vietnam ak will fire, even when dropped in mud, and water. thanks Im just glad you had the ammo, and the price was right.
-
Mikey A said:
As usual very prompt customer service and worry free shipping, love these guys & gals @ ammo.com. Well I am no expert about ammo, but I will say that this ammo was performing better than some more expensive products. fresh and snappy, good penetration and groupings 2"-3" @ 200-300 yds, mini-14 1-9 twist , similar to SS109 m855 but heavier Gr.
-
Lu said:
Glad I got it

Chrisp280 said:
Super impressed with this company
-
Bill said:
I have tried different ammo with Sig 556. Its eats everything but I find Lake City 5.56 62gr --- No failures, Accurate @ 100 to 300 yards ( my club limits ) I have the feeling of complete depenability.
-
Russ said:
This is great ammo for the hybrid AR's.The brass is good for reloading and the 62 grain bullets stabilize well. Russ

Bear Patrol said:
Ammo comes in 5 plastic mini ammo boxes that look really neat! I wish the carry handles were real but they’re still worth holding onto for future use. So far I’ve put about 360 of these through my Windham HBC with no issues. As for accuracy I’ve only fired at targets from 100 yards or less from a standing position, so I’m not sure how they do at longer ranges but they always hit where I aim at those distances. The only downside for me so far is that I have to use paper targets or improvised targets (milk jugs, cans, etc.) Because these were leaving some SERIOUS dents in my 1/2 inch thick ar500 steel target. Overall I’d definitely recommend these to someone looking for decent 5.56 ammo at a good price.

Gabe said:
I was looking for inexpensive practice ammo,and this was a good deal all around. Ammo was a good price relative to the times.Checkout was easy. Ammo was delivered quickly. Only had time for a100 rounds , no problems. Really like getting the ammo can too.
-
Matthew said:
Ammo was inexpensive and dependable. Shipping was on time. Would definitely recommend.
-
Robert B said:
This Ammo shoots well, However when trying to reload the brass I broke 2 decapping pins in my sizing die. I cut the head off two cases and found the flash hole is off center. So even though the ammo shoots well it cannot be reloaded.

I've been using PMC ammo for about 40 years. NEVER had a problem with it and AMMO.COM has good prices too.

Brian said:
My son and I have shot thousands of rounds of the PMC with no complaints whatsoever. And you won't find a better deal on 62 gr 556 bulk ammo anywhere

The ammo performed awesome.

Bone Crusher said:
Shoots straight, flying fast.

T-bag said:
For the price and quality, never thought I'd be using green tips as target rounds. My AR hasn't jammed up yet after 100 rounds or so, which is impressive. My AR is very picky on ammo, usually can't get 30 rounds out without a couple jams. But this stuff runs like butter through my AR, with some impressive penetration to boot.
-
Mick said:
All ammo went down range with consistent velocity and tight groupings. Previously purchased ammo from another party had poorly seated primers, this jamming my fire arm.

These rounds worked just fine.

RONALD said:
No surprise here but the price per round shows as 63.8 cents. With shipping and sales tax, that easily went to about 85 cents. I did receive it in a timely fashion and it was well-padded in a cardboard box but would have preferred different packing from the factory. My error. A range pack means loose rounds inside a box. The ammo itself is so-so for its intended purpose. I also purchased Belom 7.62x39 (no longer available here) and cannot address ammo quality yet, but the factory packaging (20 rounds per PLASTIC case) was phenomenal.

anthgrge said:
Subtle and accurate aim and shot , great point of contact at the target. Very effective at the range.

Gav said:
They do not run very good in a AR

primerak said:
I actually like these rounds better than the winchester boxes. seems to fly flatter.

Head hunter said:
Shoots amazing accurate and plenty of knock down power for plucking down rodents such as ground hogs . You can reach out and touch something with accuracy and confidence .

Great ammo for the price.
-
Nate said:
The ammo itself LOOKS beautiful compared to Lake City penetrators but I have not shot it yet so I can't comment on that. I paid more per round, but that is just the market, not Ammo.com.
-
Bigthiss said:
Great ammunition for the price. I used to buy the federal loose bulk ammo in 500 and 1000 but there were always at least 10-20 that were either faulty loads or misfired. This ammo is hands down the best for the price that I have purchased and shot. Highly recommend!!
-
Private citizen said:
This is a great self defense ammo at a great price.
-
Bru said:
It's Hornady Black. Goes down range well, gives decent groups at 50 & 100 Yards through a Hellion. It's not Match grade but it is consistent for my usage. Good prices and quick shipping is always a bonus too! Thanks Ammo.com

Ernest said:
Great price good rounds straight A across the board
-
THL said:
Took it out in my tavor, with a 14x primary arms scope, shoots about 2 MOA off of a bench in quick fire. Not too shabby for a HD OTM round rather than the match BTHP rounds
-
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.
