    Good quality

  • Brian said:

    No problems feeding, cycling or firing. Not a one. 500 rounds in and buying more. AR-15 platform.

  • Roge said:

    Amazing price For Some ammo!!! Without a doubt in my mind!!

  • ROLAND said:

    Not a lot of gas blow back. Nice and smooth out the barrel and suppressor. Over all highly impressed

  • Matthew said:

    The Ammo is great, but the one hitch in my "Giddy-up" is: The ammo on the website reads "FMJ-BT", but what showed up at my door was regular FMJ. I'll still shoot it, but I'll be wary, before I order from here.

  • Glen D said:

  • Bru said:

    It's Hornady Black. Goes down range well, gives decent groups at 50 & 100 Yards through a Hellion. It's not Match grade but it is consistent for my usage. Good prices and quick shipping is always a bonus too! Thanks Ammo.com

  • 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 .

  • Chris 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

    Those rounds go off every time tearing through things
