M4A1

"The M4 rifle is the carbine variant of the larger M16 series of rifles, first adopted by the US Army in the mid 1960s. The rifle is now the standard issue rifle of the US Army and fires the slim, lightweight 5.56x45mm NATO cartridge. It has a number of modern features including a telescopic stock and an integrated rail system for the mounting of optics (M150 4x optic, or the M68 Close Combat Optic) and grips. Its light weight and high cyclic rate make it a very handy weapon in various combat environments."

General Information
The M4A1 is a gas-operated, rotating bolt, magazine fed carbine. The M4A1 is an automatic variant of the M4 carbine, which is limited to semi-automatic and 3-round burst fire modes. The M4A1 was designed from the M4 and was adopted by the US Army in 2012. It became the standard assault rifle/carbine of the US Army in 2014 and is expected to replace all standard M4s.

Like the M4, the M4A1 carbine incorporates a telescoping stock, Picatinny rail, and a 370 mm (14.5 in) barrel. Like all carbines, the M4A1 is compact in size and smaller than an average assault rifle so it is easier to handle and carry. The weapon is intended for short to medium range engagements, however, it is capable of effectively engaging long range targets when used with magnified optics. The M4A1 uses ghost-ring iron sights but the Picatinny rail can house other sights for the firearm as well; many such as the M150 and the M68 CCO.

It is accurate to about 3 MOA (approximately 9cm at 100m).

Additional Information

 * It is worth mentioning that the M150 variant of the weapon has significantly increased recoil in the current build of the game. It would be expected for the gun to have the same recoil but be exaggerated due to the magnification on the weapon, but this is not the case (as seen in the image).
 * In the Alpha V5 update a significant increase to weapon sway was introduced, this can be seen greatly on the M150 variant due to the magnification of the scope.
