Customer Reviews

  • Alan said:

    Product was shiped in a timely mannner was well packaged and performed perfectly

  • 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!!

  • Chris said:

    Arrived pretty quick, packaged up pretty good, I haven't opened them to use any yet just stocking ammo.

  • Joey said:

    No issues!

  • Voltron 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.

    I've been using PMC ammo for about 40 years. NEVER had a problem with it and AMMO.COM has good prices too.

  • SAL said:

    LOVE THIS PLACE FOR MY AMMO. I AM ABLE TO DONATE TO WOUNDED WORRIER AND GET AMMO CAN'T BEAT IT.

  • Brian 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

  • Shooter said:

    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:

    same as title

  • john said:

    good product / good price

  • Snake said:

    Great ammo! Shoots and cycles perfect. Will defiantly buy more.

  • lroberts103 said:

    Great company to work with. Fast shipping great price

  • Michael said:

    This 5.56 ammo was just what my AR needed.
