M28 Next Generation Infantry Weapon
http://img.photobucket.com/albums/v383/Doomingsland/M28SOPMODthumbhole2.jpg
The M28 was designed both as a replacement to the ageing XM29 OICW, and to the venerable M27 rifle. This weapon includes both a next generation kinetic energy portion (based heavily on the Soviet Bloc designed SR90A1), and a deadly 20mm caseless grenade launcher, capable of using both airbursting smart rounds, and Special Light Anti-Armor Rounds (SLAAR). The weapon is in a lightweight bullpup configuration, saving room and improving accuracy.
Kinetic Energy System
The assault rifle's primary system is that of the 6.5mm. The 6.5mm round (140 grain) was chosen for its weight, its superior performance, and its capability. Couple this with the massive shell (7.62x54mm shell shouldered out and necked down to accept the 6.5mm), and you have a shell that can fly far, fly fast, and fly flat. This thing will rip apart its opponent at most any range, and it will do it fiercely and without remorse. You hit an enemy with this and they will go down.
The primary system is fired electronically. When the trigger is pulled (and the system is locked into 'Primary Only'), the trigger causes two conduits to touch, completing a circuit which leads to an electrical charge which contacts the shell's primer and fires, igniting the powder and so forth. The system works efficiently and allows for the soldier to actually fire both systems at once (one via electrical the other via mechanical linkage).
The barrel is free floating, which offers more accuracy.
The primary system is fed through a bull-pup type configuration (with magazine behind the trigger assembly). It accepts twenty, thirty, forty, and drum-type magazines. The standard magazine is a thirty round magazine. To replace or remove the magazine, the magazine ejection button is depressed and the magazine is simply slid out.
Grenade Launching System
Perhaps the weapon’s most deadly feature is its 20mm caseless grenade launching system. Mounted below the barrel, the weapon is duel fed from two horizontal magazines loaded beneath the launcher side by side. Each magazine contains five 20mm rounds. The rounds are loaded facing forward, similar to the way ammunition was loaded on lever action rifles in the 1800s. However, the obvious drawback is the fact that pointed rounds would be set off when the pointed tips hit the primer of the round in front of it. The caseless ammunition prevents that due to the fact that each round is encased in a small block of explosives. The reason for doing this is so both magazines can be mounted side by side to access the duel feed system on the launcher. When a round is loaded, it is pushed up into the chamber through a ramp system that separates the two magazines. Both magazines are loaded with separate types of ammunition, one with airbursting smart rounds (contains small computer that tells the round exactly when to detonate, laser range finder built into the weapon finds range of target, allowing for extremely accurate shots), allowing the infantryman to engage enemy soldier behind cover, and SLAAR rounds, allowing for an infantryman to engage lightly armored vehicles. The SLAAR round contains a HEAT warhead, allowing it to pierce up to 120mm RHA. This allows for normal riflemen to knock out APCs and other light vehicles, or even target the driver hatch of an MBT as to stop it.
The rounds are both selected via the electronic systems or manually.
Systems and Sighting
The M28 maintains a standard red dot sight which can be both manually and automatically leveled or adjusted. The red dot sight maintains twelve different settings for the size and intensity of the red dot as well as four types of 'cross hairs' [simple dot, circle and dot, diamond, cross-hairs] and can combine any of them. The M28 also incorporates a set of iron sights in the event of a red dot sight malfunction. The iron sights are universal and offer considerable accuracy for both systems.
Coupled into the red dot sight is the 'Information Display Sytem', which is a small projection system which displays data gathered from sensors inside the weapon. A laser rangefinder is included in the weapon (in between the barrels) and uses a laser frequency on the invisible spectrum, however, it can be viewed through the red-dot sight. This allows the soldier to view range to the target with the rifle and it automatically feeds that data into a computer located inside the rifle which then adjusts the red dot (or other cross-hair type) to where the soldier should aim to hit the target at the range tested. This same system gathers meteorological data such as humidity, wind-speed, and other environmental factors to compute into this as well, however, this system can be disengaged as its sometimes misleading (such as when inside a bunker, etc.).
The IDS also displays the amount of ammunition used or left.
However, the rifle was designed to be used with an infantry combat system, the VEPR NGCS, so it incorporates systems to allow for the attachment of camera, thermal imaging, nightvision, and other imaging sensors as well as other computer systems. A common rail system allows for items such as LED flashlights, vertical hand grips, underbarrel-grenade launchers or shotguns, and numerous other pieces of equipment. The rifle's computer system also maintains an uplink system for transferring data to the infantry combat system (range finder, weather conditions, etc.).
The weapon, with its advanced electronics, is also soldier-proof, with easy to use controls that take minimal time to learn. It can also stand the rigors of combat, its batteries last for nearly seven weeks without a charge (assuming non consistent firing, ideal conditons; it can also be directly linked into the VEPR system to use its power), can withstand temperatures ranging from -40 degrees to 139 degrees, and can operate in snowy, rainy, foggy, dusty, or smoky conditions with no effect on unit effectiveness. Its also fairly easy to maintain with an included maintenance booklet and tool kit inside the rear stock. It's also comfortable to the soldier as it weighs fairly light with its polymer and lightweight materials construction and has ergonomically-designed forward grips and a thumbhole-type stock. The weapon is also ambidextrous (in stock design). In addition to this, a second, manual trigger is provided for the grenade launcher. To change the 6.5mmx'06 firing mode to a left-hand operator, a small plate is flipped within its receiver and the casing ejector plate(normally on the right hand side) is flipped down over the ejector hole while a similar plate on the left side is opened, otherwise, the 6.5mmx'06 shells would hit the operator's face.
