Design History & Overview
The PR-91 (Prestonian Rifle, Model 1991) is the current assault rifle of the Prestonian military. Conceived in 1987 by a team of designers at a small civilian armory, the rifle suffered several setbacks and underwent several design changes, including a change in caliber, before she was finally approved for military use.
The development of what was to become the PR-91 began in 1987 when the military of Prestonia announced that their E19 series, by then over 20 years old, was to be evaluated and that there was a serious chance it would be retired. Upon hearing this news, the Westland Armory, already famous in the civilian sector for it's shotguns, hunting rifles and pistols, began work on a design which they hoped would win over the R&D team which was evaluating the challengers. Sadly, the PR-91, then known as the XPR-87 was not chosen, citing it's weight and questions about the rifle's ability to mount underbarrel accessories, such as a grenade launcher. Undaunted, Westland sold their creation on the civilian market as the W87, making a fortune in the process.
The next opportunity for the PR-91 came in 1991, when after several troop complaints the E19 was again put on the hot seat. Westland, which by now had merged with Augusta Arms, posted it's creation from four years prior, albeit with several changes. The fixed stock had become a folding and collapsible one. The weapon was now equipped with four rails, one on each side of the barrel. Synthetic materials and plastics had replaced many of the major sources of weight. For the armorers at Westland-Augusta, it looked like their moment had finally arrived. All that was left was the shoot-off between the two.
Sadly, it was not to be. While the PR-91 fared slightly better than her competitor, the contest had unknowingly been decided weeks in advance. The board of Eastern Military Industries Ltd., manufacturers of the E19, had payed off the evaluation board to keep their product as the standard AR of the Prestonian military. Though their creation had been superior, Westland-Augusta had been out-politicked. As one bitter executive remarked "at this rate, it'll be 91 years before our gun ever sees daylight."
Finally, in 2007, the plug was finally pulled on the E19. After 43 years, numerous troop complaints about the rifle's weight and frequent fouling and jamming had stirred the military to action. On October 3rd, 2007 the CEO of Westland-Augusta got the call his design staff had been waiting for for 20 years. The Prestonian military was interested.
The rifle as presented in 2007 was essentially the same as the one which had been presented in 1991, save a few minor changes. The rifle was now primarily composed of lightweight and durable metals such as titanium and carbon fiber, as well as lightweight shock-resistant plastics. The rifle had been rechambered to the infamous Doomani round. The Prestonian military was sold, and ordered the rifle into limited production in December of 2007. By March 2008, the rifle was in full service, and is now standard equipment for all members of the Prestonian armed forces.
Overall Design
The PR-91 rifle was built from the ground up with the mechanized forces in mind and as such is extremely compact compared to other battle rifles, particularly when the stock is collapsed and folded. With a 20 inch barrel, the rifle is maneuverable in close quarters, and accurate at long range. The barrel is free-floating, making it extremely accurate, and is fitted with a muzzle brake to compensate for recoil. The end of the barrel is compatible with several types of flash and sound suppressor, allowing for a wide degree of customization depending on what the user desires and has available.
The PR-91 stock draws much of it's inspiration from the DR-83M. Like it's Doomani counterpart the PR-91 features an adjustable cheek piece as well as an adjustable and collapsible stock. The stock features five locking notches, offering five settings for length depending on the size of it's shooter. When transported, the rifle stock is normally set to it's shortest setting and folded. While inadvisable, the stock folds in such a manner as to allow shooting to take place while folded.
The PR-91 comes with open iron tritium sights, using a front post and a rear peep sight. These provide for accurate fire in all levels of light, scoring an MOA of 1.31 in official tests. In Prestonian service, the rifle is frequently equipped with a red-dot scope of 2x magnification, which produces an extremely accurate shot.
The rifle uses a short-stroke gas piston with counterbalancing pistons similar to the mechanism on the DR-83. This mechanism allows for maximum reliability (official tests had the rifle log 11,236 shots without a jam) as well as minimal recoil.
To load the PR-91, the shooter rocks the cartridge into place until it clicks into place. The charging handle, located on the right side of the weapon, is pulled back and released. This loads the first round into the chamber. When the magazine has been emptied, the charging handle stays back in the cocked position. The magazine release, located on the receiver directly above the magazine, is pressed, releasing the empty magazine and allowing the bolt to slide forward. The process of loading is then repeated.
The receiver is milled from a solid steel forging, resulting in an incredibly durable component (soldiers claim it can stand being run over by a Nakil 1A3; official government reports have no comment.)
The rifle features a fire selector with four modes: SAFE, SINGLE, BURST, and AUTO. The burst is a standard 3-round burst.
Cartridge
The PR-91 uses a 6.7x53mm Doomani round common to the later versions of the E19. This round, which has proven highly effective in both Doomani and Prestonian service, features a "blended" construction, making use of several types of metal.The bullet itself is 135-grain; nearly twice the weight of a 5.56x45mm NATO round, it nevertheless boasts superb range and stopping power, piercing armor and soldiers with ease.
