| The '''M7/Caseless Sub-Machine Gun''' is a widely used [[United Nations Space Command]] firearm.
| |
| | |
| Ther is also a version, the [[Silenced SMG|M7/Caseless Suppressed Sub-Machine Gun]], which is equipped with a external suppressor.
| |
| | |
| == Introduction ==
| |
| | |
| The M7/Caseless Sub-Machine Gun is a [[dual wield]]able [[weapon]] seen in [[Halo 2]], as well as the [[Halo 3 Beta]], and is going to be in [[Halo 3]]. It is not a very powerful weapon and has slight design as well as technical changes in Halo 3.
| |
| | |
| == Summary ==
| |
| | |
| The M7/Caseless Sub-Machine Gun is a fully automatic, gas-operated, magazine fed, dual wieldable, short range weapon. The SMG fires 5x23mm Caseless FMJ (Full Metal Jacket) rounds from a 60 round mag with an extremely high rate of fire (which actually leads to tremendous recoil and forces the barrel upward after continuous fire). It also sports a retractable stock and foregrip. The SMG lacks range and power as well as accuracy so it is strictly a short range weapon. The Halo 3 SMG is relatively the same with minor design and technical changes.
| |
| | |
| == Physical Description And Appearance ==
| |
| | |
| The M7/Caseless Sub-Machine Gun is an automatic UNSC sub-machine gun that fires 5x23mm Caseless FMJ (Full Metal Jacket) rounds. It fires from a 60 round magazine which is actually placed horizontally on the left side of the weapon due to the way it fires.
| |
| | |
| The SMG has a polymer handle, foregrip, and stock, as well as a titanium body, and is gas-operated with a rotating breech. The SMG must be cocked before it can fire the first round. The bolt to cock the weapon is located on the right side of the gun and does not move during operation. From then on, the gases from previous rounds force the breech to rotate and chamber a new round. Once the mag is empty, the bolt (although not illustrated in Halo 2 or Halo 3) can either be pulled back and locked or it can be fully cycled after a fresh magazine has been housed. If it is first pulled back and locked, then it must be pushed forward in order to chamber a new round. There is no ejection port due to the nature of the rounds fired.
| |
| | |
| The SMG, having a rifled barrel, is 47.5cm long with the stock retracted and has a maximum length 62.8cm when the stock is fully extended. The stock is fully adjustable. The Halo 3 SMG is basically the same but has a slightly shorter foregrip and has red dots at the receiver end of the mag. This weapon does not possess a safety and is dual-wieldable.
| |
| | |
| This weapon first appeared in [[Halo 2]] and is returning in [[Halo 3]].
| |
| | |
| == Changes in Halo 3 ==
| |
| | |
| *Red dots at the receiver end of the mag
| |
| *Slightly shorter foregrip
| |
| *Increased accuracy
| |
| *Increased range
| |
| *Increased rate of fire
| |
| *There is now a few seconds before the barrel actually starts to climb
| |
| *Slightly less damage
| |
| | |
| == Against the Covenant ==
| |
| | |
| Employed against the [[Covenant]], the SMG is a very powerful close-to-mid range weapon. When fired in short bursts, it can easily decimate whole squads of [[Grunts]]. The SMG is also very useful against [[Jackals]], with the 5mm curiously "stunning" the Jackal. The SMGs large magazine size is also useful for taking out the aerial groups of [[Drones]]. Employed against [[Elites]], Dual SMGs are extremely deadly, made even more so by firing them "out of phase". However, SMGs are not effective against [[Hunters]], or [[Brutes]].

| |
| | |
| == Against the Flood ==
| |
| | |
| Like the [[Pistol]] of [[Halo:CE]], SMGs' are surprisingly effective for eliminating [[Flood]] [[Carriers]]. When Dual Wielded, SMGs are extremely deadly, capable of taking out large groups of [[Infection Forms]] and [[Combat Forms]] alike.
| |
| | |
| | |
| == Ammunition ==
| |
| The SMG uses a radically different kind of ammunition than the kind found in other UNSC weapons called the M443 Caseless Full Metal Jacket round. This ammunition is classified as "caseless," meaning it does not have a metallic casing surround the powder and sealing the bullet, propellant, and primer together. Instead of using this casing, the round uses a combustible adhesive to seal these components together. Because the chemical "casing" is vaporized when fired, there is no need to eject spent brass casings.
| |
| | |
| This feature is very beneficial. It reduces friction inside the magazine, one of the main causes of jamming in weapons. It also negates the need to expel casings, as mentioned above. This is important, as a user wielding two M7s at once would not want to have hot brass flying in his face from the eject port of the weapon in his left hand. The projectile itself is "jacketed," or coated, in metal (possibly copper or steel) to aid in penetration of the target. Caseless rounds are actually embedded into the block of propellant, reducing their length, allowing more ammunition to be stored in a smaller space.
| |
| | |
| Although 5x23mm (20 caliber) rounds would normally be considered small by modern SMG standards, the caseless layout might have an effect on the amount of gas produced when the propellant is ignited, causing a higher velocity, while the full metal jacket would ensure higher penetration than a normal lead point. This, combined with the weapons very high rate of fire, would make it powerful at close range from a realistic standpoint. The muzzle climb of the weapon would also indicate higher pressure inside the weapon, higher than what would normally be expected for such a modestly sized cartridge.

| ==Influence==
| |
| | |
| The M7 appears to take its design from three real-world firearms. The first is the Heckler and Koch G11, a caseless prototype assault rifle developed in the 1980's. The second is the Fabrique Nationale de Herstal P90. The last one being the H&K MP7. The M7 takes its concept from the G11, and its design from the latter two. As the MP7 and P90 are both personal defense weapons, it can be assumed that the M7 falls under this classification as well. Its slanted front, foregrip, and expendable stock come from the MP7; while its ergonomic grip and the horizontal magazine in a bullpup configuration come from the P90.
