223 Ammo

223 ammo is a popular choice among AR-15 shooters. With a slightly lower pressure than 5.56 ammo, you can fire 223 rounds in rifles chambered for 223 or 5.56x45. (If your rifle is chambered for 223, you should not shoot 5.56.)

We recommend rifle owners with a 1:12 twist rate shoot 55-grain 223 rounds. For shooters with a 1:8 twist rate barrel, we recommend 62-grain rounds.

I have used them on at least four occasions and always the same great service. If only there were more online dealers who took as great care with their customers would make things so much simpler thanks gunner"

The price was extremely reasonable and I don't think I can find anywhere that could beat the shipping cost. The order was shipped quickly and I was able to track the shipment with the tracking number you gave me. I knew exactly what day to expect my order. Thank You and I look forward to purchasing from you in the future."
