Bulk .223 & 5.56 Ammo

Bulk .223 and 5.56 ammo gives AR-15 owners a practical way to stock up for range training, target shooting, and high-volume rifle practice. This category includes .223 Remington and 5.56 NATO loads from brands such as PMC, Federal, Winchester, Hornady, Fiocchi, CBC, and Wolf.

Choose the Right .223 or 5.56 Ammo

Before ordering, check your rifle’s barrel marking. Many rifles marked 5.56 NATO or .223 Wylde can use both .223 Remington and 5.56 NATO ammunition. However, rifles marked only .223 Remington should use .223 Remington unless the manufacturer clearly approves 5.56 NATO.

Popular options include:

• 55 grain FMJ .223 Remington for range training
• 62 grain 5.56 NATO for AR-15 practice
• M193-style 5.56 ammo for bulk range use
• M855 green tip 5.56 where legal
• 500-round and 1000-round bulk rifle ammo packs
