Barrel length helps determine a specific cartridge's muzzle velocity. A longer barrel typically yields a greater muzzle velocity, while a shorter barrel yields a lower one. The first AR-15 rifles used a barrel length of 20". In the case of the 223 Remington (M193), ammunition loses or gains about 25.7 ft/sec (7.8 m/s) for each inch of barrel ...
The major dimensional difference between the chambers that fire the .223 Remington and the 5.56×45mm NATO is the longer and larger-diameter "freebore" in the 5.56 chamber (0.0566 in (1.44 mm) vs 0.0250 in (0.64 mm) length, 0.2265 in (5.75 mm) vs 0.2240 in (5.69 mm) diameter). Freebore is a short and smooth section of the barrel that is located ...
The .223 designation is a reference to the popular .223 Remington.

However, the .220 Swift still holds the record as the fastest .22 caliber centerfire cartridge with a published velocity of ...

Arguably, the criticisms about range, accuracy, and lethality are related to the change in barrel length and twist between the M16 and M4. The earlier 5.56 rounds (the original M193) were optimized for a 20-inch (51 cm) barrel with a 1:12 twist.
