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.

A65impalla said:
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:
Good, Clean, ammo....pricey but what can ya do....fast delivery too I cant even find a die set to reload let alone the bullets or primers so this ammo will do untill times are better....if ever

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...

gokart04 said:
Finally got to shoot some of this the other day. Worked well and shot consistant/accurate. No feeding or fire failures out of about 100 rounds in my BCM AR-15. I feel the price is a bit too high at this time.
-
J.W. said:
These were the first rounds shot through my ar. I have no complaints, it cycles fine even through rapid firing. I would definitely buy these again.
-
H.D. said:
Works great, cycles fine, glad I found your sight.
-
Pat said:
This is excellent ammo. Velocity is up there, at least in my 20" barrel DTI ar 15. Kinda lucky to buy this cheap ammo and get it to shoot the way this stuff did. I love being able to buy metal cases as well as brass cases. The metal are non-reloadable and it's nice to just shoot these and not worry about looking after shooting. I worry about the future of buying ammo over the 'net in the future. Here in Illinois our great governor Quinn moves on every front to close the avenues to get ammo. Good Shooting to All

Kenny said:
So far I probably used 100 150 rounds. No problems with the ammo at all.

anthgrge said:
Full metal jacket "brass shells" neatly packed easy to carry in convenient carry canisters. Great shot at the range.
-
Jeremy said:
Great rounds no defects and great bang for the buck
-
Kirk said:
Great service!
-
Jaden said:
Shot 30 rounds and it works well. It's nothing fancy but it's great for range shooting. Very pleased with it considering how cheap the price per round was. Definitely recommend for anyone wanting to practice some drills with an AR.
-
Wiley said:
Great prices fast shipping on all their ammunition needs
-
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.
-
Blake said:
Excellent ammo. Very accurate from the AR and bolt gun. Will be buying more.
-
Rysio said:
Very good ammo although it is Russian. Performs as expected no problems.
-
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
-
Vance F said:
I put all 500 rounds through my ar with 0 issues. The groupings are good, and not a single misfire.
-
August said:
I bought 2 of these boxes and haven’t had any problems. Goes bang every time. No misfires, no jams. I will continue using 55 grain for shooting ranges, as well as home defense situations.
-
Karl said:
For the price I'd say a good purchase. Out of 200 rounds maybe around 15-20 rounds that I'd assume had bad primers and didn't fire.
-
BWalter82 said:
This ammo is clean firing, accurate to 2 moa, and I never had a problem in any of my rifles; probably the "best bang" for the buck out there!
-
Sam said:
This ammo is low cost, performs okay, but will dirty up your bore real quick. Advise cleaning more frequently with this ammo.
-
Chris said:
No jams or any major malfunctions
-
Jiaxi said:
Very disappointing performance. In my AR-15, this ammo caused constant malfunctions — almost one failure per magazine. Frequent failure to eject and failure to feed made it extremely frustrating to shoot. The rifle runs flawlessly with other 5.56 ammunition, so the issue appears to be weak or inconsistent loading. This ammo may work in some platforms, but it was completely unreliable in mine. I would not recommend it for semi-auto AR use.
-
Mason said:
Dumped a couple 40rd mags in a brand new ar. No stoppages or failures. Worked perfect.
-
Bobber1123 said:
Love the stripper clips. I think it took just 2 days to arrive. The price was excellent.
-
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.
-
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
-
ROLAND said:
Not a lot of gas blow back. Nice and smooth out the barrel and suppressor. Over all highly impressed
-
Ernest said:
Great price good rounds straight A across the board
-
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

Private citizen said:
This is a great self defense ammo at a great price.

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!!
-
Darrell said:
Man this ammo can in, in a matter of days nice quality
-
Zachary said:
Works great out of my 11.5" bcm and my 18" 1:8 twist barrel consistent groups and no issues.
-
jerry said:
great ammo
-
J-Mac said:
Very reliable ammo and consistent. A little on the pricey side but you get Hornady quality.
-
Def said:
This stuff is cheap, and I value that. The last 4 boxes I bought are super dirty and not polished like it is 40 year old military surplus. You can see the annealing, and it looks like it came out of an ammo can 40 yrs ago . The consistency is all over the place and I wonder why.
-
Jack said:
I have always put M193 as offensive/defensive ammo, which is why I purchased it in the first place. I tested 80 rounds at 25, 50, 100, and 300 yards with a Sig M400, it was dead on accurate.
-
Mike O said:
Shot this on my high end Geissele rifle and very, very happy with it ... target practice
