YES REMINGTON FIREBALL , OLD PRODUCTION. Also, a number of companies make AR pistols in .223.
222, 223 and 9mm
The .223 Remington cartridge is primarily designed for rifles, particularly the AR-15 platform. However, there are a few pistols capable of chambering .223 ammo, such as the Sig Sauer MPX and some AR-style pistols. These firearms typically feature a shorter barrel and a pistol brace to accommodate the cartridge in a more compact form. Using .223 in a pistol can provide high velocity and energy in a smaller package, but it's important to ensure the firearm is specifically designed for that caliber.

5.56 and 223 cal. are the same cartridge...........
Yes it does, unless your barrel is stamped .223 .
Colt has not offered a AR15 in 308
Yes, you can shoot .223 Remington in a Colt M4, provided that the rifle is chambered for .223. However, it's important to note that many Colt M4 models are chambered for 5.56x45mm NATO, which is compatible with .223 Remington. Always check the specific markings on your firearm to ensure proper caliber use, and consult the manufacturer's guidelines for optimal performance and safety.
DPMS doesn't make an AR-15 - AR-15 is a copyright of Colt Firearms, and thus, only they and companies licensed by them to manufacture the rifle can actually call it an AR-15. As for their AR-pattern rifles, they typically come with a 5.56x45mm chamber, which is also capable of handling the .223 Remington.
