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.

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.

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.
