223/556/300 BLACKOUT MAGAZINES (AR15)
The standard, STANAG compliant AR15 magazine holds 30 rounds of 556 NATO ammunition in a double-stack configuration. 223 Winchester and 300 Blackout cartridges have the same diameter as 556 NATO so they will also feed perfectly from these magazines. Smaller capacity magazines are also available depending on your application and jurisdiction.
