Is 5.56x51 same ammo as 5.56x45?

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on June 30, 2022

I have not heard of 5.56x51, but there is 7.62x51. 5.56x45 is different than 7.62x51 and are not interchangeable. This Winchester USA 5.56x45mm NATO will only work in rifles chambered for 5.56x45mm NATO.

The AR 15 takes 5.56x51. What is a 5.56x45?

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on March 18, 2022

Standard AR15's are typically chambered in 5.56x45mm NATO. This is the NATO version of .223 Remington. AR15's that are chambered for 5.56x45mm NATO can shoot both .223 and 5.56x45. So if you have an AR15 chambered for 5.56x45mm NATO you can shoot this Winchester 5.56x45mm NATO 55 Grain Ball (M193) Full Metal Jacket Brass Cased Centerfire Rifle Ammunition.
