Let's see... Remington makes a variant of the 700 chambered in .223, I believe the Ruger M77 is available in .223... not 100 percent certain about the Winchester Model 70, but I believe it is or was available in .223. .223 Remington ammunition can also be cycled through rifles chambered for 5.56x45, such as the AR-15, Ruger Mini 14 Ranch (the Target models have a dedicated .223 chamber), variants of the Daewoo K2, Kel Tec SU17, some AK-based rifles, etc.
The M4 carbine is chambered for the 5.56x45mm NATO cartridge. It will also accept .223 Remington rounds.
The M16 assault rifle is chambered for the 5.56x45mm NATOcartridge. It can also fire the civilian .223 Remington round.
