RAWR!

User Image

(The illustration above presents a model with both the top fed and bottom fed magazines in place, although the side magazine is rarely used and usually disconnected from the device all together.)

Basic Information


The weapon is made entirely out of synthetic materials such as black fiberglass-reinforced polymer for the pistol grip and heat shields, as well basic polycarbon composites, along with polymer and alloy-based materials. While it's complex material use is somewhat difficult to produce, it is actually cheaper, lighter, stronger, has a higher tensile strength, and is more resilient than previously used materials (such as stamped aluminum or wood, which require 2nd, 3rd, and 4th parties to physically remove the products from the ground and carve them into usable shapes, where as the composites usually take one or two parties to achieve the proccess).

The magazines are essentially 100 or 50 round translucent polymer cases, that are roughly 685mm long. They exploit a "turning" mechanism to slide the sideways loaded round into the chamber, basically just like the P90's. The magazines, being similar in size, do not require a large amount of changes- they are, however, different in length, as the rawr's magazine is nearly twice as long and holding twice as many rounds. The magazines are designed to be capable of stacking on top of each other, although this removes a number of rounds from the original magazine platform. The round loss is not completely infringing, as two stacked magazines results in a 190 total round combination magazine. A maximum of three magazines can be stacked upon each other, creating a 280 round load.

The barrel is a heavy, free floating polygonal hammerforged 24 inch barrel, that uses a 6 groove 8 inch twist. The barrel of course, is intended to use tombac coated 6.5mm grendel rounds, which are typically high explosive incendiary armor piercing rounds. It's accuracy is considered superb even for ordinary rifles, and being fully automatic the weapon preforms excellently. The firing system allows the weapon to be fired with very little recoil, allowing the user to operate the weapon without risk of the weapon "jumping" or experiencing muzzle climb, also increasing it's accuracy. The barrel is suspended in the rifle using impact gel inserts, which support the barrel and absorb the recoil of ordinary impacts, allowing the barrel to stay freefloating without the ordinary possibility of being misaligned due to excessive wear or force.

The round itself stays supersonic for 1200 yards, has an extremely flat trajectory, and a very predictable flight path. An infrared laser, designed specifically for the weapon, is usually positioned above the barrel, which is bent at an angle that represents the weapons usual flight path up to 600 meters. While not always completely accurate, it is a good representation of where the estimated bullet target will be up to 600 meters.

Firing System


The new rifle features a balanced system that functions along the lines of Newton's third law of motion, which states that for every action there is an equal and opposite reaction. This system uses a recoil-dampening countermass mechanism with two operating rods that move in opposite directions, thereby providing "balance". One operating rod, the upper, has a gas piston facing forward while the bolt carrier also has a gas piston. The gas tube at the forward end of the handguard is double-ended to accommodate the two rods. The enlarged gas tube cover of the upper handguard guides both rods in their travel.

When the rifle is fired, gas is tapped from the gas port to enter the gas tube, driving the bolt carrier to the rear and the counter-recoil upper rail forward. The critical timing of the reciprocating parts is accomplished by a star-shaped sprocket that links and synchronizes both components, causing both to reach their maximum extension, or null point where forces are exactly equal, at exactly the same instant. The felt recoil is therefore eliminated, enhancing accuracy and assisting control during fully automatic fire. The RPM is potentially elevated to 900 RPM from 600 RPM, due to the shorter strokes than a conventional AK-47 platform, which is selector controlled in 100 RPM increments from 600 to 900. However, as the felt recoil is virtually eliminated, the manufacturer claims that accuracy is enhanced, especially during burst fire. An enhancement of 1.5 to 2 times has been reported.

Rather than using the farily conventional rotary bolt with dual locking lugs operated by long-stroke gas piston located above the barrel, it instead exploits the same system derived from the AR-18 and G36 rifles, used in the HK416 Rifle. The bolt is a 7-lug rotating type, which sits in a bolt carrier and operates in a forged alloy receiver resembling those of the Stoner-designed AR-10, AR-15 and M-16 series weapons. It is gas-operated, with a short-stroke piston design similar to those found in the HK416, G36 and ArmaLite AR-18. The HK416 uses a proprietary gas system derived from the HK G36, replacing the direct impingement gas system used by the standard M16/M4. The HK system uses a short-stroke piston driving an operating rod to force the bolt carrier to the rear. This design prevents combustion gases from entering the weapon’s interior, a shortcoming with direct impingement systems. The reduction in heat and fouling of the bolt carrier group increases the reliability of the weapon and extends the interval between stoppages. It also reduces operator cleaning time and stress on critical components. The SA80 bull-pup assault rifle used this system long before the HK G36 was developed. According to H&K "experience that Heckler & Koch gained during its highly successful 'midlife improvement programme' for the British Army SA80 assault rifle, have now borne fruit in the HK416."

The same firing system exploited in the RAWR! weapon system, although it also uses the counterbalance system used by the AK-107-Ak108 series. The needs to be cleaned and thoroughly examined after every 10,000 rounds, which is relatively high due to the stronger firing system and fact that it fires from a "Closed bolt" (although no bolt exists on the weapon).
