    Ran flawlessly, not one jam or problem. Great price and fast shipping.

  • Richard said:

    Great ammo and the delivery was even better than expected

  • Mike said:

    Good value and quality ammo

  • Sharpshooter said:

    I would defiantly recommend this to any AR owner! Clean, Good accuracy , No Misfires, No Fail To Eject, No Fail To Load just keep on shootin worry free! Normally it's a lot cheaper hopefully soon this ammo hording will stop and we can all get the fair market price.

  • Tarpon said:

    As expected

  • NuSparkey said:

    Nothing like using good ammo to make you feel good about yourself. Pushed it out to 300 meters and anything off target was probably my jittery finger. Cycled well under rapid fire. I like it!

  • Rick said:

    No FTF or FTE's in my Ruger Mini-14

  • Jack said:

  • Carl said:

    Will be ordering more I am very satisfied with the delivery and price ammo shoots good

  • AZ SHOTGUN said:

    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!!

  • SH in TX said:

    This ammo has proven to be the most accurate I've found out of a Remy 700 HB with a 1:12 twist. Had almost given up on accuracy with this rifle, but this load yielded 0.7 MOA (100 yds, calm day, off support).

  • 6/8 said:

    They work great and the price is good

  • USA GUNNER said:

    GOOD AMMO AT A BETTER PRICE

  • CRAIG said:

  • Bushwacker61 said:

    I have bought lots of 1,000 of this ammo 2-3 times. The first lot(s) were good. However, I started getting tons of split case necks about every 10th round with my most recent lot. This was with a 10.5" AR pistol and good quality P-mags. I had my local gunsmith look at the gun, and he couldn't find any issues, so presumably the culprit was the ammo. Not sure if they had some QC issues this year? I haven't written off Fiocci, but I'll probably wait a while until any bad ammo cycles through the market.

  • Ezekiel said:

    Ive been shooting fiocchi 223 amd 9mm for a couple years solely now, never have had a malfunction, bad primer, or defaced/damaged round. Shoots great, burns well, and such a good price for what you get.

  • EmmBee said:

    Purchased 1000 and reloaded those after shooting. Ammo functioned beyond expectations and reloaded cases performed well too.

  • Gary said:

    I have a bear creek arsenal upper in 223 wild with a 20inch SS slick side charge and man I'm telling you that this stuff shoots 5 shots into 1/2 inch groups all day long, I bought this ammo because it shoots as flat as a 22,250 55 grain bullets do, I've yet to shoot any yotees yet but when I do you guys will be the first to know, I can't wait!!!!!

  • Gwp said:

  • Freakazoid said:

    This ammo is very consistent. Bench firing my Sako .223 I can put three consecutive rounds in a nickle at 100 yds. Love this ammo!

  • Al said:

    As good as Federal and a lot less expensive.......Federal is supposed to be the Cadilac of ammo.....well, PMC is equal if not as good or even better.....I am a user from now on.

    CANT GO WRONG WITH THIS AMMO

  • ammo said:

    remington did it again with another great ammo and ammo.com low price you can't bet it.

  • 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

  • Larry said:

    good ammo at an excellent price

  • Rico said:

    This is a quality bullet

  • Mad Dawg said:

    Service and shipping is top-rate with these folks.

  • 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:

    Worked great

  • Echelon 9 mm said:

    Very pleased with this ammo that I bought It looks to be well put together every round shot as it should I didn't have any jamming issues everything fed the way it should Good ammo I'll be buying it again.

  • 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.

    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.

    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 .

    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!!!

    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.

    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.
