M40A1 

The M0A1 is the USMC's Scout Sniper Rifle. Based on the Remington 700's action the rifle is hand assembled by the Corp's highly trained expert armorers. It is equiped with an Unertl 10x scope specially contracted by the Marines. The rifle maintains one minute of angle(MOA), in other words it holds a one inch group at 100 yards, 2 inch group at 200 yards, etc... In the hands of an experienced marksman it is accurate up to 1000yards (915meters)

M40A1 

A modern 7.62x51 Nato bolt-action sniper rifle used by the Marine Corps.

"The hapless Taliban group was pinned down behind a rock, trapped out in the open. We had them. Two of their buddies lay dead. Their AK's were useless. One of them made the mistake of peeking out from the rock. He lifted his head up again. I saw his eyes through the Unertl's 10x scope. It looked as if they met mine, even though he couldn't see where we were. Then.."

M40A1 

A long range sniper rifle that is preferred by the Navy Seals. It can often be mistaken for a .30-6, though the two weapons are radically different.

With this M40A1, I can shoot you in the crotch from 800 meters.

The M4 Carbine is a shorter and lighter version of the M16A2 assault rifle, achieving 80% parts commonality with the M16A2. As with many carbines, it was meant to provide troops with an effective, shoulder-fired weapon in lieu of pistols, such as the M9. Since the weapon is shorter (and therefore lighter), it is handy and more convenient to carry than a full-length rifle. While this makes it a candidate for non-infantry troops (vehicle crews, clerks and staff officers) it has been used by US Special Operations Command (SOCOM) and others seeking a compact weapon for close quarters combat.

The M4A1 was developed and is produced for the United States government by Colt Firearms, who has an exclusive contract to produce the M4 family of weapons through 2009.

The M4A1 carbine, an improvement upon the M4 carbine intended for Special Operations use, features a fully-automatic fire mode, a flattop NATO M1913-specification rail on top of the receiver (for attachment of optics and other devices), and a detachable rail-mounted carrying handle. The M4A1 can be found in use in many US military units, including the U.S. Army Rangers, the elite Delta Force, U.S. Navy SEALs, and the United States Marine Corps Force Reconnaissance companies. Variants of the carbine built by different manufacturers are also in service with many other foreign special forces unit, most notably UK's SAS and Australia's SASR.

The M4A1 Carbine is specially favored by counter-terrorist and special forces units because of its compactness and firepower that the rifle offers for close quarters combat (CQB). It is very useful in urban warfare. Although the M4 does not have as far an effective range as the longer M16, many military analysts consider engagement with a non-specialized small arm above a range of 300m to be unnecessary.

The Special Operations Peculiar Modification (SOPMOD) I M4A1 Kit was developed by USSOCOM for use with units under its jurisdiction. The kit features an M4A1 rifle, a Rail Interface System (RIS) handguard system developed by Knight's Armament Company (KAC), a shortened quick-detachable M203 grenade launcher and leaf sight, a KAC silencer, KAC rear back-up sight, an Insight Technologies AN/PEQ-2A visible laser/infrared designator, along with Trijicon ACOG, Reflex optics and a nightvision sight. This kit was designed to be configurable (modular) for various missions and the kit is in service right now with Special Operations units (though many soldiers have changed the Trijicon Reflex sight for M68 Aimpoint red dot sights and EOTech holographic sights).

A 2nd generation SOPMOD (now known as SOPMOD II) is currently under development, with many different manufacturers competing for a contract. Notable manufacturers include Knight's Armament Company and their URX II, ARMS and their Selective Integrated Rail (SIR) system, along with Lewis Machine & Tool's Monolithic Rail Platform (MRP).

The M4/M4A1 5.56 mm Carbine is a gas operated, air cooled, magazine fed, selective rate, shoulder fired weapon with a collapsible stock. A shortened variant of the M16A2 rifle with a 36 cm barrel, the M4A1 provides the individual soldier operating in close quarters the capability to engage targets at extended range with accurate, lethal fire. The original M4 Carbine had "semi" and three round burst fire modes, while the M4A1 has "semi" and "auto" but no three-round burst. The M4A1 Carbine achieves over 80% commonality with the M16A2 Rifle and was intended to replace M3 .45 ACP submachine guns and selected M9 pistols and M16 rifle series (though this plan may be changed with the development of the XM-29 OICW and the XM8 carbine with most Army units.) It is capable of mounting the M203 Grenade Launcher.


I had to apologize for making this definition so damn long.

M-40A1 

The weapon widely regarded as the "Ultimate Sniper Rifle". Basically, it's a modified Remington 700 rifle. Introduced late in the Vietnam War.

M4A1 

Colt M4A1 Carbine
5.56x45mm NATO

The carbinized version of the venerable M16 series. The M4 carbine is used mostly by US special forces, but it is even used by the Israeli military. It is said that the M4 carbine will replace the M16A2/M16A4 assault rifle as the mainstay for the Us armed forces...
...but in MY opinion, I think the M16 should stay. The M4 is a great weapon and is battle-proven, but the M16 has a few advantages still over the M4. Although the M4 is full-auto (the M16 only fires 3-round bursts for its full-auto mode), very compact, and heavily upgradable, the M16 has power and accuracy. The M4, on the other hand, excels in other areas over the M16, but it's not as accurate or powerful as the M16.

The idea of the M4 replacing the M16 should be heavily under debate. For now though, the M4 is a favored carbine for our special forces.

"The M4 is a really pimpin' gun. Too bad civilians can only buy those Bushmaster ripoffs."

M4A1 by Dave February 4, 2004

M4A1 

A kick ass quality rifle chambered in 5.56x45 Nato rounds, same rounds used in the M16A2 (which is more accurate and has better control)and the M249 (inaccurate compared to the M16 and M4A1 but accurate enough for covering fire). But although to due the slight disadvantages from the M16 it has auto fire feature, it is ultra-upgradeable and its compact, and the model of the weapon is just superb.

Although the M16 and the M249 are good weapons, the M4A1 pwns.

I'd take a M4A1 any day

But one day they are doomed to be replaced for the OICW.
