Can You Put a .300 Blackout Round in a 5.56 Magazine?

The short answer is: no, you absolutely cannot. Attempting to do so is incredibly dangerous and could result in serious injury or death.

Here's why:

The Critical Differences Between .300 Blackout and 5.56 NATO/.223 Remington

While both .300 Blackout and 5.56 NATO/.223 Remington cartridges are used in AR-15 style rifles, they are fundamentally different in size and design. The key differences that make them incompatible with each other's magazines are:

  • Caliber: The most obvious difference is the caliber. .300 Blackout is a larger caliber (.308 inch) than 5.56 NATO/.223 Remington (.224 inch). This means a .300 Blackout round is significantly wider.

  • Case Length: The .300 Blackout cartridge case is longer than the 5.56 NATO/.223 Remington cartridge case. This difference in length prevents the .300 Blackout round from properly seating in a 5.56 magazine.

  • Magazine Design: 5.56 magazines are specifically designed to accommodate the dimensions and shape of 5.56 rounds. They are not designed to handle the larger diameter and longer length of the .300 Blackout round. Forcing a .300 Blackout round into a 5.56 magazine would likely damage the magazine and potentially the firearm itself.

The Dangers of Trying to Force a Mismatched Cartridge

Attempting to force a .300 Blackout round into a 5.56 magazine could lead to several dangerous scenarios:

  • Magazine Damage: The magazine will likely be damaged, rendering it unusable.

  • Failure to Feed: The round may not feed correctly into the chamber, causing a malfunction that could leave the weapon inoperable at a critical moment.

  • Chamber Obstruction: The round might partially feed into the chamber, creating an obstruction that could cause a catastrophic failure upon firing, potentially leading to injury or death.

  • Bolt Damage: The larger diameter of the .300 Blackout round could damage the bolt and other internal components of the rifle.

Using the Correct Ammunition is Crucial

Using the correct ammunition in your firearm is paramount for safety and reliable function. Always double-check that the ammunition matches the specifications of your firearm and magazine before loading or firing. Never attempt to force a round into a magazine or chamber that isn't designed to accommodate it.
