Customer Reviews

  • Rodge said:

    The service was excellent. The performance of the Aguila .223 Rem FMJ ammo is superior to ammo that cost more. It is excellent quality brass and I've not had a single failure to date in over 1250 rounds fired over a three month period.

  • Zombiesrnuts said:

    Ammo.com had the best price per round for the Aguila and also was pleasantly surprised on the ease and quickness of the order and delivery! I'll always shop here first!

  • 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:

    Great ammo and a very reasonable price. Great service.

  • skywarrior said:
