CQB 50cal : Preview by Shimmering-Sword CQB 50cal : Preview by Shimmering-Sword
I have a bit of a project going on by the side, working on it a little every few days. I'm not sure how far I will render it, it's just a good practice of my technique.

Here's a preview crop, and a stand alone shot of my 50 cal rifle (cqb short barrel).

The design is very similar to the CARB in Avatar universe

Clean boxy guns, a common concept.

Hmm.
I find it interesting that when my brother told me to look up a cqb 50,
I happen to find yours first on the list.

For CQB use, you could go caseless, you could also try telescopic rounds.The military was messing around with those as a way to save weight, while still being able to carry the same weight of the bullet. (don't ask me how it all works, they've been doing tests with an M249) It's all just a suggestion. You may have to create a whole new round though. something that either hits as hard as a 50cal or a magazine that'll hold a good amount of ammunition. (drum/ barrel magazine comes to mind) Like the others have said, I think you've got a whole lot of potential to make your ideas a reality.

Got a link to any pics of such telescopic rounds?
Caseless is pretty dead afaik, saves brass, but little else.
The purpose of the gun is teamwide armor penetrating capability, versus heavy infantry.

Unfortunately the last time I read about the telescopic rounds it was in the Army Times. I can't find the article anymore and I've been looking online. Now I have found a picture of it: [link]

It is the one on the left.

armor penetrating capability, versus heavy infantry... Is it going to be general issued to everyone, or is it a specialized like a grenadier, SAW, or a DMR?

It's used in teams of the same "heavy" infantry, meaning muscle suits and moderate armor padding, like these [link]
About 1/3 of the team will have these penetrator rifles, then others with more modest calibers, and some with heavy weapons. These teams are rare, and are used in battle to combat. In regular infantry squads such a caliber would instead fall to a DMR.
So telescoping is shorter, and a little fatter, doesn't sound as lame as caseless :D

Very nice concept. Would bring up the issue of carrying all that ammo. What's the magazine capacity, just wondering?

Haha, yea when I first (3D) modeled it I didn't give that much thought, until I found it only carried about 8rds. Then I double stacked to get 14 in the mag, but that still wont do will it :D

That was a while ago though, I'm going to design a new cartridge, may/not be a lower cal, but the main point will be to reduce the brass (propellant) area diameter, that should get more rounds in there.

You could try a .408 caliber. Large and heavy, usually used for sniping. Has better accuracy and distance than a .50 cal.

The goal of the round would be to deliver maximum force and armor penetration at conventional rifleman ranges. Do you think a longer round would do this better?

Oh and thanks for the faves btw.

rymth Featured By Owner Aug 13, 2009
Yes, generally the bigger the better. But when considering it's designed for a CQB environment, one can give up 'some' size for the ability to carry more ammo, in the mag and on the person.
Anyways, why use a .50 cal when you've got a grenade! jk

hey everyone has done it including me when in the Hayfong story I made the MR-C (Modular Rail launcher- Carbine) that fires a 6.8mm x 30mm rail. no recoil though thanks to the use of rail balancers and that the gun pulls the rail out of the barrel please don't steal this

Shimmering-Sword Featured By Owner Jul 18, 2009  Professional Digital Artist
Rail balancers, do you mean a counter weight that moves to kill the recoil? It's a good idea, but it would have to have a low rate of fire to not cause recoil as it resets.
And just to be sure, your not one of those newbs that thinks rail guns make no recoil right?

IMO, rail guns will only work the best on large emplacements, like ships (seen TF2? :D ) As for the power needed, you could use propellant in the same space for rifles, unless batteries get a looooot better.
But go for it, just drop the special tech, recoil isn't that bad, but those extras are heavy and don't really work.

no actually i wrote a physics paper (89%) for my community college intro to physics on rail weapons the gun uses a small coil system as well to increase the power its meant for close quarters and the M-10 is a more powerful choice for open areas like urban warfare weapons like the MR-C is meant for SWAT and military units that perform in building combat. The ISMC has a small exoskeleton that allows soldier to carry the mirco rail cannon. In hayfong aliens gave humanity well the Inner Sphere anti grav tech that make fighters perform 23G manuvers with no effect on the pilot and the ASF-4s have aero-elastic armor that make the pull that stuff of without damage the teran Federation also has the grav tech but its only starting to field thing like the CSF-44 Vampire which is as fast as the ASF-4D super Raven which is only avalible in small numbers to the Inner Sphere forces that are trapped on Hayfong. The command carrier defiant has thre forward firing Rail guns that send out a three mile long slug from the back of the ship out the front. thank god for sci fi as I always say check it out [link] I need to post the other chapters

yeah i write sci fi with some belivability and the defiant is about 120miles long thanks to the Riglan's cheap cloning of matter that they shared with the known races of the galaxy including the Federation that is hell bent on human suppremecy and has wipped out a race of lizardish humanoids that never left their system or made much of a military due to the fact that they coexsisted since recorded time the Inner Sphere tried to protect them but lost misrably as their own military wasn't ready to fight that close to federal space and after they began project control making military fort worlds called Control 1-3 with four on the way carriers are 3miles and are smaller then cruisers are 7-8 miles in length to sheild the carriers and the majority of the ship's systems are automated giving the crews the ability to focus on fighting

I just hope that is not a .50 BMG but a more manageable .50 cal.
Looks good.

Yea think of a half way between the bmg and the ammo used in the beowulf m4. Big bullet, slight less grain.

No sir, they wont be getting back up either.
The rifle is meant to combat similar foes with strong body armor. It even gives them some punch against full power armor, but they have more suited weapons to handle that.

50 cal bullpup? How does its target groupings look? Also how about recoil?

:iconshimmering-sword:
Shimmering-Sword Featured By Owner Jun 19, 2009  Professional Digital Artist
Haha, kicks like hell and wont hit the same place twice :P
Well the infantry that use it have muscle suits that make the recoil manageable, and running the sights through their helmet makes keeping on target an easier task.
Oh, and thanks for putting me on watch man, I'll keep the stuff coming.

SuskaSuina Featured By Owner Jun 19, 2009
heheh

couple technical points I'd make;

"muscle suit" : Muscle isn't really the issue, the energy has to go somewhere. What you'd need is some kind of impact distributer - unless you've come up with a way to translate kinetic energy into some other form of energy in which case, assuming its portable it'd be part of the gun. My concept would be that the soldier's interior armor is a series of cased elastic straps that diffuse the recoil throughout the whole body-suit. It could look something like my City-Ball under-armor: [link]

"remote sighting" : Here the issue isn't whether the gun is pointed in the right direction, but how tight its target grouping is; suppose you clamp the gun to a big rock so that it absolutely will not move and fire off hundred of shots, each shot will still vary where it hits depending on its spin as it leaves the barrel. Even very sophisticated weapons shoot a little bit different each time. The reason pistols are used in short range is they suffer a great deal from this effect due to their short barrel. The higher velocity the projectile (50.cal armor piercing is as high velocity as small arms gets)the longer barrel is required to keep it on target.

Your weapon would dislocate an unprotected shoulder and probably fire with less accuracy than a pistol unless we can come up with some sci-fi rationale.

I've been thinking about hand held rail-gun designs lately... doesn't help us with recoil much or barrel length, adds another issue too because of power requirements.

Some sort of caseless .50cal ammo in a bullpup weapon would be really nice though.

Or, how about a short range explosive shotgun round, who needs accuracy when you can can shoot through cinder block walls, right?

Well its not just a suit to assist weight lifting. Similar to the suit in Crysis, it can tense and aid stability when the soldier fires. So like you say it needs, it can distribute the recoil across the body. Not to mention these tough elite soldiers with thick armor and training could fire it without the stability aid. I've seen barret marketers fire their 50 one handed and easily handle the recoil, muzzle break is the key.

This is a bullpup, but for a 50 it is still very short barreled, so no it's groupings will not be comparable to sniper 50s, as this is not a sniper. It's purpose is to penetrate body armor in an urban battle environment, at shorter ranges. Most are equipped with the standard barrel though, just the (unseen) soldier in this picture has a sniper rifle, so this is his side/backup rifle.
Yea the integrated sighting is purely for fast resighting if recoil throws off the aim.

Armor piercing delayed explosive if needed here :)
