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.

You know exactly what they have, and it's almost always a better price than anywhere else you might find. There are never backorders, so you're not dissapointed when you open your package to find half of your order not filled. You can count on your ammo being delivered to your front door in just a few days after you place your order. I have told my family, friends and people at my shooting club that Luckygunner.com is the best place for all of your ammo needs."

They were easy to find and navigate their web page.The selection was out standing and great prices. The thing that stood out the most was there customer service. You know all about your puchase and where it is until it reaches your front door, then they e-mail to make sure you recieved it. They are a company that knows customer service is what can make a company in difficult economic times."
