M4A1

Real Steal
The M4 carbine is a shorter and lighter variant of the M16A2 assault rifle. The M4 is a 5.56×45mm NATO, air-cooled, direct impingement gas-operated, magazine-fed carbine. It has a 14.5 in (370 mm) barrel and a telescoping stock.

The M4 carbine is extensively used by the United States Armed Forces and is largely replacing the M16 rifle in United States Army and United States Marine Corps combat units as the primary infantry weapon.

The M4 is also capable of mounting the M203 and M320 grenade launchers. The distinctive step in its barrel is for mounting the M203 with the standard hardware. The M4 is capable of firing in semi-automatic and three-round burst modes (like the M16A2 and M16A4), while the M4A1 is capable of firing in semi-auto and full automatic modes (like the M16A1 and M16A3).

In Game
The M4A1 can be used by players on the US forces. The weapon features a 30rnd Magazine as well as Semi-Automatic and Fully-Automatic fire. The M4A1 has a considerable fast fire rate and high recoil. Holding down the trigger will result in your weapon pointing up to the sky. To combat against the recoil, fire in Semi-Automatic or short 3rnd burst. On Semi, the gun will fire as fast as you can pull the trigger.

There are multiple attachments that are added to the M4A1 with different roles. The 'Recruit' role will use a standard M4A1 with no given attachments. The 'Rifleman' role comes with 3 options of attachments. Either, Red Dot Sight (Offers no magnification), Optic (Magnifies when ADS), and a vertical grip. 'Squad Leader' has the choice to chose between a Red Dot Sight or Magnification Optic, and the 'Medic' will receive a Red Dot Sight. Both the 'Light Anti-Tank' and 'Grenadier' roles will receive an M4 with Red dot sight however, the 'Grenadier' will also have an under-slung M203 Grenade Launcher at their disposal.
