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

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.

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.

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.

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.

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.

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.

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.
