RSR-51 Next Generation Infantry Assault Rifle

The RSR-51 was developed to give the ARSB a weapon to master both areas of combat, the accurate, long-range style (field combat) and the short range, close quarters style of urban warfare. This was accomplished by not finding a compromise in a round, but rather creating two seperate systems in one rifle. Because, why bother reducing lethality in field engagement just so you can have a good round in close quarters combat, when, not all combat is located within 200 yards of an adversary. The RSR-51 combines both worlds with a 7.62x51mm primary round to engage targets up to 1000 yards away with superior penetrating power and sub MOA accuracy; and a 5.56x31mm (.221 Fireball) secondary round to provide a fast firing, short range round perfect for engagements within 200 yards.

The RSR-51 maintains an internal system that links two seperate control systems, one based near the primary trigger, the second based on the forward grip. Each one has a series of buttons to switch firing modes between primary and secondary and to choose from Semi-auto and burst on the primary round and burst and auto on the secondary round. The RSR-51's fire control is all electronic meaning there is no actual physical connection between the trigger and the pin (which is 'hydraulically' driven by a small cylinder and a fluid that when hit with electricity expands and therfore knocks the pin out to hit the primer), except it does maintain a connection to the 5.56x31mm barrel and firing system, in the event the electronics fail. When the firing mode is set to the 7.62 barrel, a small motor system disconnects the trigger system from the 5.56x31mm firing system. However, when firing the 7.62x51mm round, trigger pressure is still maintained via a 'hydraulic' cylinder with a conduit running through it, when the trigger is pulled back so far (trigger pressure), the contacts touch and electricity is forwarded through to fire the round. A small device then acts to push the trigger back into the original position. An interesting feature of this is the dual-fire mode, which allows both systems to be fired at once, one using the pyhsical connection, the other using the electrical connection. This allows an infantryman to become a mobile firing system, peppering targets with heavy rounds and much more smaller rounds


Now, you may be asking about ammunition weight... Yes, that is a factor, a factor our soldiers can ignore. Due to the VEPR AMDCS infantry combat system, infantry can effectively carry three times the ammount (or weight) of ammunition than a non-VEPR system equipped soldier can. This allows us to use either heavier rounds or carry more ammunition, we decided we'd carry heavier rounds but still carry more ammunition than the normal soldier would.

The other notable feature of this weapon is its modularity... The 7.62x51mm 'primary' system can be easily removed, leaving the 5.56x31mm 'secondary' system... Also, night-vision, scopes (red dot, enhanced vision, or zooming), infrared, laser rangefinder, laser designator, and satellite uplink systems can be added on in bundles or singularly easily and efficiently. The RSR-51 can also accept most types of grenade launchers, under-barrel shotguns, and other barrel-mounted amenities (sp?). When a grenade launcher or shotgun is added on, the controls can either remain on the added weapon itself, or be integrated into a button-firing control system, which is wired to the two control 'centers' on the forward grip and near the trigger.

Another very notable feature is its advanced combat system inter-operabiliy. Being designed for the ARSB and its soldiers, it was built with that in mind, to have an easy way to hook up the camera and other systems that are used in conjunction with the VEPR system. However, this system doesn't only accept the VEPR suit systems, but can also accept systems from other notable future warrior systems such as LandWarrior or Future Force Warrior, making it an ideal weapon for those suits. Can you imagine a future force warrior-type soldier running around with a weapon mounted with up to three different modes of fire (7.62x51mm, 5.56x31mm, and either shotgun or grenade launcher)? Oooh... One word: Destruction.

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 56 hours without a charge, 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). To change the 7.62x51mm 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 7.62x51mm shells would hit the operator's face. This does not need to be done to the 5.56x31mm system.

What about recoil? Hmm... If a soldier can't handle the recoil of a 7.62x51mm round, why the hell are they in combat?! Besides, when coupled with numerous systems, recoil is reduced phenomenally (sp?). Besides, it was primarily developed for the ARSB soldier who wear the VEPR combat system which maintains equipment to reduce felt recoil on the wearer. The 5.56x31mm's recoil? Pfft, it has NONE (well, a bit). What about controllability? Well, with its design, it is VERY controllable with little barrel jump, even when firing bursts with the 7.62x51mm.

Comments? Questions? Anything?

Interesting configuration.

dual-fire mode = cool

Weight of the weapon itself still seems to be an unresolved issue...and what about the threat of Electro-Magnetic Pulse bombs? A simple EMP weapon could render all of your rifles inoperable, thus leaving your forces totally vunerable... :twisted:

About the EMP threat, not necessarily, to harden the systems requires a small amount of time and money, but it can be done. But this risk was known before hand, but what enemy would fire an EMP on the enemy they're fighting when that same EMP will render their electronics useless as well? (Although it will have a more profound effect on the men with the RSR-51)

Plus, the only ability you lose is your 7.62x51mm system, not the 5.56x31mm (due to actual mechanical linkage). So the men are far from defenseless although the 5.56x31 does lack some 'power', although it is only slightly smaller than the 5.56 NATO round. So, if the enemy does resort to EMP, the soldiers with this system still have a viable defense tool and if the 7.62x51mm system is fried, it can be removed leaving the much lighter 5.56x31mm system. And if its hardened against EMP (only the firing system, not any peripheral devices), you only lose night vision, laser rangefinding, etc, not the firing ability of your weapon.

The weight is fairly heavy but the M-16A2 can weigh in at just under 20 pounds with all add-ons (M203, NV scope system, etc.).

At about 9 and a half pounds, the system is actually really light for what you expect. The OICW base weapon weighs in at somewhere around 13-15 pounds and that has a grenade launcher and built in heavy electronics, unlike this.

Bump.

Why not make a timed-sabot round that opens at long distances, leaving the sabot to go farther?

short range:
you>------Normal Flight------>enemy

long range:
you>-------Normal Flight---------------o--------Sabot------------>enemy

In any case, nice system, and can you give a link to your VEPR system?

Hmm... A sabot round. Well, it doesn't really work in conventional weapons as the pressure from it firing (and the blow-back gases) is too much for the sabot... I don't know, a timed sabot round could work (if it was completely enveloped in the casing). I'll have to see about that one.



VEPR AMDCS Infantry Combat System (http://www.nationstates.net/forum/viewtopic.php?t=135920&start=0)

Doujin will... blah *tag* wait til tommorrooowww

A very interesting appraoch, so basically you are giving your troops a sort of PDW inspired priamry weapon (based on what little actual stuff i can find on .221fireball it is being comapred somewhat to 5.7mm FN, 4.6mm HK and .224Boz) with an optional long rnage attachment for those occasions firepower is required beyond 200m (although to be honest 6.8mm grendel will give you better perfromance at 1000m than 7.62mm NATO will, apparently).

A nice idea but persoanlly i'll stick with my 6.25mm round, all the power of 7.62 at 600m but with 5.56mm recoil...

Well, we would've gone with a different round (I was considering the 6.8mm as well as a vast array of other rounds, both smaller and larger), but with the amount of weapons that we currently use that are configured for the 7.62x51mm, we'd rather like to have some comminality between our ammunition.

The .221 Fireball is a round developed that has the same penetrating power and velocity as a 5.56 NATO (.223) with less recoil and better effectiveness at closer ranges. At least that's what I've been able to find about it.

Eh, to tell ya the truth, recoil really isn't too much of a problem to our soldiers, as most of them are outfitted with the VEPR AMDCS system, which really reduces felt recoil on the soldier and therefore reduces exhaustion, battle fatigue, etc. So we aren't really limited on recoil.

Anyways, yeah, we wanted a system to give our soldiers optimum ammunition for the two main types of engagements... And to give our soldiers twice the firepower (the dual-firing feature; one using the mechanical linkage, the other using the electrical linkage). And we were able to accomplish that with minimal weight and size gain. And with a grenade launcher attachment, this is truly a mobile gun system.

Bump.

Bump.

Where are these avaliable for purchase?

Right here, in this thread...
