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.

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
-
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.
-
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.
-
Jetson said:
Goes bang, burns clean, shoots straight no ftf’s or any other issues. I’d trust my life to it. Gonna get more.
-
CDH said:
Shipped quickly Haven't had a chance to send some down range. But sure they'll be fine
-
Christian said:
Shot 100 rounds through my new AR-15 and everything was flawless. Very happy with the service, delivery time and quality of the Ammo.
-
Capt AR said:
Spent 30 rounds @ 100 yrs.Fired prefect and only a couple off Mark.
-
Cameron said:
Great shipping shoot fine at 100 yards could drill dime every shot
-
michael said:
Ok
-
Chris said:
I bought 500 rounds of the 556 FMJ out of the first few boxes (60 rounds) 11 have failed to fire. Firing pin struck the bullet but no boom. Will not be purchasing again.
-
Jamms said:
Price was pretty good. But constant jamming and feeding issues in all 3 of our weapons. Casings seem soft. Not sure about that though. They did stay in decent groupings on the target at 50 yards. Oh and the damn boxes all came apart, had to just dump em all into a bucket. Frustrating because I like to just take one or two boxes to the range. But anyway.
-
Signman said:
Jammed every other round. Very disappointed.
-
JRL said:
I got 1000 rounds of this. Just shot it today and it consistently chronos 100fps slower than advertised. NOT HAPPY AT ALL. Order another brand if you want full power ammo.
-
Daddy-O said:
Amazing service, value and speed of receiving my order! Will be ordering again soon!
-
Edward 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.
-
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:

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.

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.

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.

great ammo

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
