Basic Information


The weapon is made almost entirely out of composite polycarbon synthetic materials, similar to that used in the P90, FN-Five Seven, and Ak-108 weapons. This material is cheaper to produce, lighter weight, and stronger than conventional stamped steel or wood, although harder to produce (specific shapes must be molded for each specific application rather than simply "Stamped out" or carved). The Barrel, chamber, and parts of the magazine are all made out of steel, with the barrel having a protective chrome lining to help resist corrosion, while the screws and other likewise attachment devices on the weapon are high carbon galvonized iron. The basic magazine is rotating, helical, 100 round stacked drum magazine, that is purely mechanical in nature using a series of gears, with a translucent flexible body made out of the same material found in the Hk416 and XM8 magazines. While it possible to possess both 50, 100, and 200 round drum magazines for the weapon, 100 round drums are the commonly produced magazines, and specially designed for the weapon. The weapon also uses the counter-balance system found in the Ak-108, which vents excess gas and uses rebounding kinetic energy to send a counter weight backwards inside the rifle to balance the weapon. The service life before the weapon needs any internal materiel replacements is roughly an estimated 20,000 rounds, with reports of only "225 jams per every 60,000 rounds fired in a dust filled environment", or 37.5 per every 10,000 rounds fired. The weapon also has three fire selectors- Semi-Auto, Burst, and Automatic. In burst mode, the weapon fires three rounds per every trigger pull, although this is technically possible be pushed to either two or five, although it involves a large amount of gun-smithing, engineering, and personal tinkering. The gun has a felt recoil of roughly 2 joules, which is practically nothing.

Extended Information





Material Composition

The weapon is made from roughly the same materials found in the P90 and Fn-Five Seven weapons, using high grade, light weight polycomposite polycarbon polymers. These materials are actually cheaper, stronger, and at a lighter weight for it's strength in comparison to basic materials such as stamped steel and wood, although more complicated to produce. The cost efficiency of the material is cheaper mostly due to the ability to fabricate the material rather than to find it, and in the fact that less man power is required to create and achieve the finished project (two steps compared to several for mining steel or chopping down trees for wood). The material is also composite, meaning that several lightweight materials, alloys, and plastics of differing flexibility and hardness can be used to achieve the end product rather than simply creating a "Super Material".

The stock is covered in a 1/8 inch thick black film of Impact gel, which increases the comfortability of the weapon and greatly reduces the nearly non-existent felt recoil. The same material is used on the grip, potential fore-grip, grenade launcher accessory, and sides of the weapon to increase the over-all comfort and felt recoil reduction of the weapon.


Magazine

The magazines are molded from a high-strength translucent polymer similar to what is found in the G-36 and XM8 rifle magazines. The magazine case allows for a lightweight, cheap, and flexible translucent material to view the rounds left inside the magazine. While not quite as rigid as steel, it is considered to be just as strong, if not more useful than standard steel constructed boxes.

The empty magazine weight is roughly 1 lb, or .45 KG. Fully loaded, with 100 rounds, the magazine weight is roughly 3.2 lb, or 1.45 KG. The Magazine also holds two end pieces of steel.

The basic magazine is essentially a helical, 100 round cross spiral mechanically powered gear driven magazine, that is powered to be in perfect synchronization with the firing system (although not programmed to be in perfect synchronization, as it's in fact the opposite). The magazines are designed to be relatively cheap, and achieve their power from the weapons primary firing system, or an external power source, rather than an internally driven power source to save on weight, price, and the complexity of the magazine itself.





Scope

The scope is essentially an enlarged TA11J-308: 3.5x35 Trijicon ACOGĀ® Illuminated Scope with Green Crosshair .308 Ballistic Reticle to basically fit a 4x40mm scope designation. The .308 ballistic reticles, which are pre-made and established to accurately follow the flightpath of the 7.62mm x 51mm NATO rounds to 1200 meters, reflect almost exactly the same flight path for the 6.5mm Grendel Rounds, with only a slight yet seeming unnoticeable difference. The primary marked difference between the standard 6.5mm Grendel rounds and the standard 7.62mm x 51mm NATO rounds, in ballistics flight path expectance, is basically the expected MOA, or accuracy, rather than the predicted flight path; although certain specific "Sniper Specific" 7.62mm x 51mm NATO ammunition carry a marginally different flight path and greatly increased MOA or accuracy in comparison to the .308 styled ammunition.

The scope of course, has a 40mm Thermal Vision addition which is expected to be added to the front, that allows the same view to be seen during the day time and night time with relative ease. The thermal addition also displays everything seen on the PDA in a HUD, including the round counter, current firing style, and RPM and burst amount selected.
