Warning: Missing argument 2 for format_text() in /home/www/ddgaz1/inc/main_functions.php on line 203
The .223 Remington was developed as an enlarged and higher velocity version of the .222 Remington, which had existed in the 1950's as a varmint cartridge. The .223 Remington was developed specifically for the Armalite AR-15, which later became the U.S. military rifle M-16.
