DR-83 21st Century Tactical Rifle

http://img.photobucket.com/albums/v383/Doomingsland/DR-83-2g4.png

Design History and Overview

History has proven that "the more expensive a weapon is, the further behind the lines you have to send it to get it fixed." The DR-31 Assault Rifle has served in the legions of the Empire for many years, and has done so with distinction. With its high capacity magazine, superb accuracy, and compactness, the weapon has proven itself in combat on many an occasion. If there is one thing that Legionaries absolutely HATE about the DR-31, it is its complexities. First off, the weapon requires a battery simply to fire do to its electronic operation. Its caseless ammunition has also generated questionable performance in desert environments, prompting most legions stationed at home to adopt modified DR-78 battle rifles as their primary infantry combat weapon.

The complaints of the men did not fall on deaf ears, thankfully. Upon hearing of the issues, designers at Doomingsland Defense Industries set to work on a brand new rifle to meet the needs of the infantry. Working from experience with the DR-78 series of battle rifles, DDI designers knew what the men wanted in terms of performance. Of course, the legions were often engaged in fierce urban battles, such as the Battle of ViZion City, in which the DR-31 had proven itself as an excellent weapon for close quarters fighting.

The DR-78, firing its massive 7.8x63mm cartrage, was ill-suited to this kind of fighting. That, and it was a big, unwieldy weapon. This was not something a soldier wants to use to clear out a building. Looking back at such designers as Springfield Armory and Armalite, specifically the AR-10A4 and SOCOM-16 rifles, both chambered for 7.62x51mm NATO, DDI found precisely what they wanted: a compact, powerful, accurate weapon, capable of delivering the hurt from five hundred yards away, or just a few feet away. And do it without having to resort to a complicated electrincally-operated assault rifle.

Enter the DR-83 Tactical Rifle: a compact, poweful rifle, optimised for use with the heavily mechanized Legions in both a big, open battlefield, or the confined spaces of a building. From its sheer modularity to its superb reliability, the DR-83 delivers virtualy everything the men were asking for. And more.

Upon the weapon's release, it quickly found a relatively good market. The weapon has been adopted by numerous nations other than the Empire. Other than Imperial forces, it is in service with Tyrandisian special forces, the Spizanian Confederate Guard and Marines, the Parthian army, along with numerous other nations, and is currently under review by a number of other armed forces.

Overall Design

The DR-83 was built from the ground up for use with mechanized infantry. Thus, it is relatively compact in comparison to other battlerifles, such as the DR-78. Making use of an eighteen-inch steel barrel, the weapon is both maneuverable in close quarters scenarios, and lethal at great range. The barrel itself is free floating, allowing for even greater accuracy. In order to compensate for recoil, the barrel is fitted with an advanced muzzle brake. While this does increase the sound produced when firing the weapon, this is traded off with vastly reduced muzzle climb and lessened recoil. While the weapon is generally issued with a muzzle brake, the barrel itself is threaded, allowing for the shooter to swap it out with a variety of other accesories, such as flash or sound suppresors. The barrel is forged from 4150 chrome molybdenum steel and given a black finish, producing an excellent component.

Also aiding in reducing the weapon's size is the lightweight telescoping stock. This stock is very similar to that found on the American-made M-4 carbine. Centered around a strong, hollow steel cylander, the stock is capable of maintaining a high-strength buffer spring, allowing for overall recoil to be reduced. The purpose of the stock is to allow the shooter to easily adjust the length of the weapon based on personal preference, environment, and the gear he's wearing. A storage compartment is built into the side of the stock, allowing for the storage of a cleaning kit. A rubber pad can be fixed to the butt, further reducing felt recoil.

In order to be more maneuverable at closer range, the weapon had to be relatively light, while still maintaining low recoil and overall strength. As a result, the weapon's furniture (handguard, pistol grip, ect.) are constructed of a strong, lightweight polymer, allowing for a tough weapon that is still lightweight. The actual vented handguard maintains an advanced integrated rail system. This consists of four rails: a top rail, which runs along the whole the the weapon, two side rails, allowing for the mounting of flashlights, and a bottom rail. This allows for numerous accesories to be added: a forward assualt grip are generally mounted on the bottom rail to allow for easier handling of the weapon, while flashlights and lasers are often mounted on the side rails. The top rail can accomodate numerous scopes or even an ACU-352 semi-automatic grenade launcher. The pistol grip is highly ergonomical, allowing for easy use and added accuracy.

In regards to sighting systems, the DR-83's own iron sights are quite superb. Tritium sights, good for both day and night combat, are used with this weapon, using rear peep sights and front post sights, allowing for quick and easy range and wingadge adjustment for open engagements over long distances. These sights feature an MOA of 1.25, allowing for accurate fire over long ranges.

The weapon's operation allows for the greatest possible reliability. Using a long-stroke gas piston, as found in both the M-1 and AK-47 rifles, the weapon produces superb results in the area of reliability (tests by the Imperial Government put 10,000 rounds through the weapon without a single failure). Unlike most rifles, this configuration is not reliant on a tight fit with the bolt group. Rather, it uses rails along with irs recoil spring guide rod and long stroke piston to help keep the carrier in line, while leaving ample room for debris to fall. The DR-83's recoil reduction system is also utilized, reducing the hitting of metal against metal in the operation of the bolt.

Loading the weapon follows as such: The shooter rocks the magazine into place until it locks in nice and tight. With that accomplished, he or she pulls back the charging handle, located on the right-hand side of the weapon. By doing this, a round is exracted from the magazine. The shooter then simply releases the charging handle, letting it slap forward. This method of operation is quite common among other rifles, such as the Kalashnikov series, meaning that training a soldier to operate the DR-83 takes little effort.

The weapon's reciever is machined from a solid 4140 steel forging. While this method of manufacturing is more difficult, it produces a far more rugged, superior component. Tests by the Imperial Government on DR-83 recievers found that they were capable of withstanding tremendous pressure.

The trigger group is carefully machined and features an ultra-smooth pull, meaning that the shooter won't move the weapon nearly as much when squeezing off a round. This adds to the accuracy. Also aiding in accuracy is the use of a titanium hammer rather than a regular steel one.

Stripping down the weapon is incredibly simple: one needs only to remove the dust cover, withdraw the recoil spring, and pull out the bolt and piston to field strip the DR-83. This process is very similar to field stripping a Kalashnikov rifle.

The magazine cache is similar to most other rifles, requiring the magazine to be rocked into position in order to lock in. The magazine used by the DR-83 is similar to that used by the DR-78, constructed of black bakelite. This is both relatively strong and extremely cheap.

The selector switch is located on the left side of the weapon above the pistol grip. This allows for extreme ease of access, allowing the shooter to switch rate of fire with the flick of the thumb, without taking his hand off of the pistol grip. The switch has four settings: 'SAFE', 'SEMI', 'BURST, and 'AUTO'. The weapon's burst function is a two-round burst, allowing for greater accuracy. The magazine holds twenty-five rounds, however, a one hundred-round steel drum can also be fitted, and is widely used in the light machinegun variant of the DR-83, the DMG-83.

Cartrage

Drawing on experience from both the DR-31 and DR-78, designers and Doomingsland Defense Industries put together a round that would have managable recoil but superior kinetic energy and knockdown power. The result of this was a blending between cartrages: the 6.7x53mm Imperial cartrage. Standard issue cartrages use a 135-grain bullet. While it is more than twice as heavy as the 5.56x45mm NATO cartrage, it is still light enough to allow for superb kinetic energy from the long case, which is acualy a shortened, necked down 7.8x63mm case.

Using advanced quick burning powder and superb ignition with a steel case, the 6.7mm cartrage's combination of weight and kinetic energy produces what the Empire sees as the perfect round: excellent range, excellent penetration, excellent terminal performance. This allows for the penetration of body armor at long ranges while maintaining awsome knockdown power. When used in close quarters, the 6.7mm cartrage is positively deadly, piercing most body armor and dropping men with a single hit. When used in two-round burst, a kill is almost assured.

In order to penetrate armor and put down an enemy soldier, DDI designers came up with a blended metal bullet for the new 6.7mm cartrage. While this round is seen to have questionable results by some nation's militaries, blended metal rounds have served the Empire well through multiple wars with distinction, effectively penetrating body armor and causing horrific wounds.

We thank you all for your input. If appears that the DR-83 would be a good match for the Army. A few questions though:

1.) How long does the battery last?
2.) What's the capibility of integration with modern battlesuits/armor?
3.) Can grenade launchers be mounted (M203, AG-36, etc)?

Thank you again.

Hali-42 Assault Rifle
http://modernwarstudies.net/Lineart/bullrsm1.png
[This wonderful drawing was done by Mekugi.]


Abstract:
The Hali-42 is the next generation assault rifle designed for use in the Macabee army, destined to replace the long worn Hali-21, which has been the mainstay of Macabee forces for over a decade. The new rifle is the product of better understanding of rifle mechanics, as well as the developement of newer technologies that guarantee the superiority of the Hali-42 over older designs, although the project takes a wild turn away from previous design dogmatics, including a once determined stance on keeping the conventional rifle configuration, and the uses of caseless and cased ammunition. There has also been a very steep change in manufacturing technologies and rifle theoretics that have called for a change in the conentional 5.56mm NATO round to something radically different and lighter, although no less lethal, with even less recoil. The Hali-42 is within all meanings of the name, the epitome of Macabee rifle design, never known for its small arms ordnance.

The rifle uses a bullpup configuration, following the recent rise of bullpup rifles, but attempts to capitalize on the configuration to increase potential muzzle velocity, allowing for greater penetration. It also relies on caseless ammuntion, as opposed to cased ammunition, and Kriegzimmer has underscored this by converting manufacturing to mostly caseless ammunition, although it keeps the manufacturing of cased ammunition to be able to remain selling the Hali-21 and Hali-37 in the foreign market. There has also been a very new change in the propellant, and in general length ratios of the barrel to the rest of the rifle. The designated marksman rifle as includes very powerful scope technology.

Furthermore, unlike its predecessor, the Hali-21, the Hali-42 is an assault rifle in all aspects of the name. The Hali-21 was more accurately a battle rifle, using a 7.62mm round, which is one of many reasons why the change from Hali-21 to Hali-42 ultimately occured. The Hali-42 project also made the decision of ignoring international conventionals, and opted to use more lethal, but less 'civlized' round technology, including the use of the barbette. In the end, every little changed detail makes the Hali-42 amongst the more potentially lethal assault rifles in use around the world.

The Ejermacht has announced its decision to replace all existing Hali-21 rifles with the newer Hali-42, and it's expected that the international world will respond as well - mostly those that used the Hali-21 as their standard assault rifle design. This includes at least one million rifles for frontline use in the Ejermacht alone, not including stocks for reserves and replacement. The Hali-42 has the potential of being a very widely used assault rifle.

Operation and Recoil:
This particular assault rifle operates on delayed blowback, seen in action on the Heckler & Koch G3. This is to allow the rifle all the advantages of a blowback operation without limiting range or eventual muzzle velocity. Interestingly, the first prototype of the Hali-42 actually used an inertia operation on the rifle, but theoritically, the delayed blowback can be translated into a delayed inertia, offering all the recoil operations of an inertia weapon and giving it the power an effective assault rifle needs. A lot of inspiration to incorporate the delayed blowback, roller lock operation came from the Spanish CETME modelo 58 [now replaced], which's initial design was based off the model 45 Assault Rifle.

Further recoil is handled by the exceptionally small round in use [see below], a two round burst as opposed to a three round burst, and a muzzle break. Unfortunately, all these designs are counteracted by the fact that the rifle uses a magnum configuration, powering a 73 grain round with a large binary liquid propellant.

Frequent Rounds Operated:
.221 Aluminum Orchomenos
The new .221 bullet design is designed to keep the underestimated possiblities of the .221 Fireball, but to make it even lighter, allowing for an even greater achieved muzzle velocity. Total weight of the round is 73 grains. The rifle round has excellent aerodynamic properties at long ranges, mirroring that of the Fireball, which has already been suggested by many to replace standard NATO rifle rounds for the M-16 . In fact, throughout its history, the .221 Fireball has been underestimated by most. Fortunately, its cause has been understood by Kriegzimmer, and so an improved version was destined for use on the Hali-42. At the tip the round uses a series of barbettes, first used in the American Civil War, and it's designed to cause major damage within the impact zone, making the round harder to extract, and more damaging to the human body. Beyond that, the round also uses a delayed electrical spark fuze, allowing the round to puncture, then blow, causing the explosion to theoritically occur inside the victim's body, not on impact. Maximum muzzle velocity with the .221 Orchomenos has been caught at 1,070 meters per second.
[b].223 API Orchomenos
The .223 API Orchomenos is an armor piercing projectile designed to penetrate battle suits at high velocities. The round replaces the .221 Orchomenos when an enemy is known to use battle suits, but normally, the rifle uses the .221 version. This round also uses an internal barbette to maximize potential damage, with a delayed fuze.
.221 Binary Sarin Orchomenos Biological Round
In compliance with foreign needs, a variant of the .221 Orchomenos was designed to carry Sarin to make it even deadlier. Although not standard in Macabee forces, it is a round manufactured by Kriegzimmer. In order to increase shelf life the Sarin is composed and stocked in a binary method, making shelf life rather irrelevent. The round spins on terminal flight to produce the effects of Sarin. On impact the round will cause bleeding at several points on the subject, and permanent damange to the central nervous system, possibly killing them, but more likely to put them out of action indefinately. The Ejermacht has ruled out the use of Sarin rounds, but it is a popular export. Muzzle velocity, since the round is a tad heavier, is around 990 m/s.
Additional Information:
The Hali-42's barrel is fully modular, allowing it to be exchanged quite easily by camp forges in order to use other rounds. It can also be sold with a specialized muzzle to cope with the purchasing nation's round of choice, allowing the Hali-42 to be highly versatile and not dependent on the round in use by the Ejermacht. In other words, the barrel is interchangeable, although not on the field. The rest of the rifle is modular as well, making cheap replacement parts for the rifle easy, and making for a very simple cleaning operation.

ICCD would be interested in knowing more about your .22 AP rounds, it doesn't seem physically posible to build a normal AP round that small and get modern armour sheathing pentration?

How is it done, curious, we may be interested in buying the rights to the round if it is actually effective.

The .221 Orchomenos relies on velocity over mass, hitting at what's considered a very high speed. We understand that in case of very heavy body armour, like battlesuits, the .221 would simply be too small, and thus the .223 Orchomenos would be used in its place. The 7.92mm round is a .224 round. Furthermore, to avoid overpenetration of such a small round it features the barbettes, which are technically illegal by Geneva convention, but who follows the Geneva convention anyways? The barbettes would ensure that any wounds are not clean. The .221 Fireball is considered as ballistically capable as a standard 5.56mm round, which is slightly larger, with the same penetration capabilities - the .221 Orchomenos is fully superior to the .221 Fireball.
