5.56mm M-4 CarbineThe M-4 Carbine is a shortened M-16A2 rifle introduced in 1988. It has replaced about 10 percent of the M-16s in the Army (as of 2003) and has been issued to Marine units selectively. However, it is not intended to completely replace the M-16. The advantage is that the M-4 Carbine is smaller and more compact and most soldiers carrying an M-16 would rather be carrying an M-4. It’s smaller, lighter and is better for shooting out of vehicles.
Description of the M-4 Carbine
The M-4 or M-4A1 5.56mm Carbine is a shortened version of the M-16A2 rifle. It is a lightweight, gas operated, air cooled, magazine fed, selective rate, shoulder fired weapon with a collapsible stock. The M-4 Carbine achieves over 80% parts commonality with the M-16A2 to simplify logistics. It will replace all M-3 .45 caliber submachine guns and for certain service applications, it will replace M-9 pistols and regular M-16 rifles. The M-4A1 has a rail-mounted forward handgrip, a telescopic stock, a removable carrying handle and Military Standard 1913 (MilStd 1913) accessory mounting rail for night vision sights, combat optics, red-dot laser sights, flashlights or other add-ons, even the M203A1 grenade launcher. The trigger unit is also modified to fire full-auto rather than three-round bursts. The M-4A1 Carbine Special-Operations Peculiar-Modified (SOPMOD) is described on the linked page.
