- "The M4 carbine is a family of firearms that was derived from earlier carbine versions of the M16 rifle, which was in turn derived from the original AR-15 rifle that Eugene Stoner designed and ArmaLite made. the M4 is a shorter and lighter variant of the M16A2 assault rifle, with 80% part commonality."
- — In-game description
The M4A1 is a common military weapon which can be found in military installations and buildings throughout Chernarus.
The M4A1 is chambered for the 5.56x45mm cartridge.
With the default stock and handguard, the M4A1 is extremely inaccurate. For comparison, it has 4 times the dispersion of the mod's M1014 shotgun.
The M4A1 carbine is part of the family of firearms that was derived from earlier carbine versions of the M16 rifle, which was in turn derived from the original AR-15 rifle that Eugene Stoner designed and ArmaLite made.
The M4A1 is a shorter and lighter variant of the M16A2 assault rifle, with 80% parts commonality.
The M4A1, is designed almost-completely for close-quarters combat. The M4A1's accuracy impedes it beyond medium range, even when the weapon is in pristine condition. Attachments such as the ACOG 4x Sight as well as the Magpul Stocks and Magpul Handguards will significantly help increase the rifle's effective distance, but it will still lag behind other rifles like the Mosin 9130.
However, even with a Magpul-upgraded M4A1 and attached with a ACOG 4x sight (see attachments for further information), the M4A1 can still remain inaccurate at even medium range (250-300m). It is recommended to switch the rifle to Semi-Automatic ("T" Key) at longer range, to reduce recoil.
It is important to learn how the rifle shoots and works in order to maintain a reasonable range with the gun, as well as the use of flanking, ambushing, and/or suppression. It is important to take advantage of the rifle's close-ranged effectiveness, automatic fire coupled with compact size creates a perfect close-quarters weapon.
- Note: users have reported differences in accuracy which may stem from the gun's condition. Other factors that come into play are health, control of breath (resting/prone position and using right-click to stabilize), condition of all parts (including mags/ammo). There does not appear to be any "wind" factor for shots. Many users have been able to repeatedly make headshots on targets > 250m out using ACOG optics, bipod deployed, fully healthy in a prone position.
The M4A1 has many attachments with various purposes, these parts may commonly be found in military installations and buildings.
 Handguards and rails
An M4A1 handguard that provides a base for the rail based attachment system.
It provides 4 Picatinny rails, one each in the 12, 3, 6, and 9 o'clock-positions for mounting lights, lasers, bipods, grips and optics.
Enables use of Weapon Flashlight when equipped.
 Sights and Optics
Warning: It is buggy at the moment, magnification level is only 1.65x. (01/06/2014)
An attachment for the barrel of a firearm which significantly reduces the amount of noise and flash generated by firing the weapon.
This variant is designed specifically for 5.56mm caliber and uses a quick detach system for quickly mounting/dismounting onto the flash hider of the host rifle.
NOTE: Suppressor will not work optimally without SD Low Velocity ammunition. Regular 5.56mm ammo will still report a sonic boom with each shot. As this ammo is not currently in the standalone, this suppressor is useless.
This bipod provides solid support for longer range engagements, will allow for greater weapon accuracy when deployed and user is at a prone stance.
It has to be deployed manually by right-clicking in inventory.
A bayonet can be found and attached to the underside of the M4A1, on the opposite side of the barrel under the front sight.
It can be used to open cans.
