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.

Customer Reviews

Vlastimir said:
Every 3rd to 5th round had a deep seated primer. For the value it was a good deal but nothing is worse on range day than pulling the trigger and no bang.
-
John said:
I think these guys might be the best kept secret in the industry. They’re a legitimate military supplier for multiple EU countries, so the M193 designation on the box is MIL SPEC not just a marketting buzzword. I’ve probably bought and fired more than 5,000 rounds of Igman, and I’ve never had a single failure. It’s accurate, runs clean, and always works. There isn’t much more you can ask for from an ammo manufacturer.
-
Michael said:
Fast delivery, ammo is nicely packed into small boxes. Definitely will order again!
-
JV said:
As the title states it fired every time I pulled the trigger and I was satisfied with the grouping at 50 yards with just a Trijicon MRO. For range training ammo I wouldn't hesitate to order it again. Plus the shipping and order processing was very fast! All good.
-
David said:
Performs well
-
Joe said:
As far as the look and the function of the ammo I’m really pleased with it. The price met or was cheaper than competitors. They were packaged well and clean. They also fired great out of my AR. The thing that stood out the most was the fact that I made my purchase on July 3rd around noon and I received the ammo on July 4th before noon. I was so surprised! I will definitely be ordering here in the future.

Jim 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.
-
olbull said:

Justis said:
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.

I have a Ruger AR556 in which Ive shot 200 rounds of Winchester 193 556 with no problems accurate at 50, 100 and 200 yards
-
Ben said:
I got good ammo at a good price and yes this is a real review I highly recommend it
-
John said:
Outstanding job, I will use this company and tell my friends.
-
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
-
Joe said:

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 .
-
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
-
J-Mac said:
Very reliable ammo and consistent. A little on the pricey side but you get Hornady quality.

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!!
