Important Safety Information
When using 5.56 NATO 62-grain FMJ, it’s essential to ensure that your firearm is chambered specifically for 5.56 NATO to handle the higher pressure. While 5.56 NATO cartridges can fit in .223 Remington chambers, firing 5.56 in a .223 chamber can lead to excessive pressure and damage to the firearm. Always double-check your firearm’s compatibility and consider using hearing and eye protection due to the cartridge’s higher velocity and noise level.
Frequently Asked Questions (FAQ)
