>The Army has identified a potential gap in the capability of ground forces and infantry to penetrate body armor using existing ammunition. To address this operational need, the Army is looking for an Interim Combat Service Rifle (ICSR) that is capable of defeating emerging threats

>The service plans to initially award up to eight contracts, procuring seven types of weapons from each gunmaker for test and evaluation purposes. Once the review is concluded, the service "may award a single follow-on Federal Acquisition Regulation (FAR) based contract for the production of up to 50,000 weapons," the solicitation states.

>The Army's Interim Combat Service Rifle should have either 16-inch or 20-inch barrels, a collapsible buttstock, an extended forward rail and weigh less than 12 pounds unloaded and without an optic, according to a May 31 Army request for information.

>The competition will consist of live-fire testing and evaluate the following:

>Dispersion (300m - function, 600m - simulation)
>Compatible with Family of Weapon Sights -
Individual and laser
>Weapon length (folder or collapsed)/ Weight (empty/bare) / Velocity (300m and 600m calculated)
>Semi-Automatic and Fully Automatic function testing (bursts and full auto)
>Noise (at shooter's ear) / Flash suppression
>Ambidextrous Controls (in darkness or adverse conditions) / Rail interface
>20-30 round magazine to support a 210 round combat load
>Folding sights

So anons what's the best tool for job?

Just fucking use m995 or the 308 equivalent or get some 20 inch barrels and use m193 or better yet the new m855a1 with the hardened penetrator. What they want they already fucking have. Or just make a new hardened steel core bullet if the tungsten carbide m995 is too expensive.

This.

we all know the sensible answer would be an AR10.

yikes. with that 100 trillion a year budget they really cant figure out 260 is a superior caliber.

>>34768675
No you wouldn't, just take off the barrel and get a 20 inch one. And do they still have the 20 inch m16s? I'm sure they do in some warehouse.
>>
>The Army's Interim Combat Service Rifle should have either 16-inch or 20-inch barrels
Why? The M16 was ditched by the marines and has been more or less phased out by the army because it was long and the extra length and weight didn't really translate into improved performance downrange compared to the 14.5 M4A1. Why are we doing this all over again, trying to make everybody into an DM.
>So anons what's the best tool for job?
Probably a SCAR, SOCOM already use them and the military gets them way cheaper.
>>
H&K M110A1, the amount of waste in the US military must be astronomical.
>>
>>34768700
so now we are sending a hundreds of thousands of rifles to depot level maintenance to be converted. then we have to convert them back to 14.5 barrels when we inevitably change ammo again.

Army should have just fielded all Scar Hs plus 5.56 conversion kits. This would also allow for 6mm conversions in the future.

someone just needs to make an ar-15 with a bigger magwell to fit larger mags so you can load 80-90 grain 223 bullets and take advantage of their out of control ballistic coefficients.

also trijicon needs to make a 4x acog with 3 inches of optimal eye relief instead of 1.5. army is ran by retards and people making contract money.

Harder to control in full auto vs 556, and that's the only comparison that really matters. Then everything associated with it weights more so you carry less of it on top of the already too much equipment.

In the vacuum of space or in a pressurized vessel? If vacuum, use the lowest recoil cartridge possible that will pierce the space suit and torso. Like .17 HM2. If it's pressurized then you need to actually kill him via blood loss so bump up to 5.56.

plz plz plz I love swiss guns
>>
>>34769135
Thermal shock, certainly. Going from ambient temperature of 3 Kelvin to whatever the approximate temperature of firing would likely cause damage to the weapon.

Rather than redesign the weapon, an insulated cartridge could be used. As I recall there are Russian or Soviet handguns that use a modified 7.62x39 cartridge that contains the gasses. Insulate the cartridge so thermal shock doesn't fuck up the internals.

I'm not sure how much good rifling will do in space, but friction has to be minimised to be able to have barrels with a practical lifespan. Teflon coated bullets might help, but I can't imagine that being economical. I can't really think of any other solutions without veering off into science fiction territory.
>>
>>34769266
The problem is not thermal shock, the problem is there's no way (beyond radiating it away slowly) for a gun in space to get rid of the heat.
>>
>>34769014
the M14 would win in a tile truck testing competition done by big army.
>>
>>34769263
I dont know, just seems weird. Like selling someone a kit to convert their civic into a lambo, and the kit is just a lambo with no wheels.
>>
>>34769320
Radiating on Earth is slow, sure, but in space it is a bit different. The Stefan-Boltzmann Equation describes the behaviour of radiators depending on their environment.

eσA(T4 - Tc4)=P

Where e is emissivity, σ is Stefan's constant, A is the radiating area, T is the temperature of the radiator and Tc is the temperature of the surroundings. P, in this case, in the net radiated power. I'd imagine that heat dispersal wouldn't be too much of an issue unless in direct radiation such as unobstructed sunlight. In which case, some sort of refrigeration and heat equalization would be needed. I can't think of an effective solution for that outside of specific radiators that aren't exposed to sunlight, like those used on satellites. Even then, those have pipes in order to transfer heat, but the presence of a shadow and direction of the radiator are both problems in that regard.
>>
>>34768464
They're only ordering 50,000 of whichever one wins. This is not a replacement of 5.56, it's the Army getting more DMRs. I for one welcome an American take on the SVD concept.

300. blk is basically fucking done for at this point then. If light weight ceramic armor is the chief concern that the modern militarizes are going to base their doctrine around then that will halt the further adoption of all but a very few units.

The best thing about this is that this proposal will be Commercial off-the-shelf or commercially available off-the-shelf (COTS) just like the MHS pistol program.

This means we will probably get a new generation of battle rifles (biggest competitors will probably be FN MK17 SSR, LMT 308MWS 2.0, HK 417A3, Knights M110 2.0, tavor 308) like we did with windernines (M&P2.0, FN 509, beretta APX, Glock Gen 5 and SIG P320)

Push for a 7.62 NATO infantry rifle was the brainchild of an HK gun salesman who was highly connected in the Army. He wanted to push the HK417 (which turns out to be a pretty shitty gun) so he created a powerpoint presentation that top level decision makers would see that emphasized Taliban outranging our guys by hundreds of meters based on by-the-book manual copied max effective range for point targets. So now the viewers of slideshow are like "Holy shit, i knew it was bad but not this bad!"

The HK merchant knows he has them at this point, the hook is in, they believe we're getting hammered in A-stan by small arms when though small arm casualties are the lowest of any conflict we've ever fought. Now its time to set the hook and yank. After showing the graphs of range parity against goat herders with occasional buttfuck rusted PKMs, his next slide is pic related, grossly incorrectly labeled as "Russian infantry squad in Ukraine"

Rooms suddenly smells like feces because a bunch of ignorant brass, who don't know any better but should, just shit themselves.

"Mother of God, do they really have two PKs, a VAL, and a RPK-74 in every squad? As God is my witness, I will fix this!"

HK guy is thrilled, victory is his. But he dies before contract is signed and now HK's 417 has a shitty reputation and most likely won't win the procurement selection for an entire new infantry weapon requirement they created out of thin air in the first place. Instant Karma. RIP IN PISS Jim Schatz.

I suspect they'll suggest a Mk17, but also a FNAC-style Mk17 to lower cost for the army and increase their chances.

That said, I kinda doubt this procurement proposal will actually go anywhere.

Since FN-H has gotten the short end of the stick so often, it's possible they just decide not to compete with anything they don't already have. Meaning only the Mk17 will get entered.
Making new guns each time the US military asks for something gets expensive as fuck when each time the military backs out for political reasons.

Brett Westcott who ran the program from 2006-2010 had this to say.

>This is a very STRONG disconnect between what most of the trigger pulling operators are saying and what makes it to the decision makers. There is a bold and obvious movement against the SCAR program at many levels inside key positions all the way up the chain of command. I am not going to give specific names or positions; I don’t think that is a good way of doing business, but I do know who they are and why they are doing it! I’m sure one day it will all come out.

It took the secretary of defense ordering the M16 to be implemented immediately and unchanged to overcome the army corruption 60 years ago.

Back then there wasn't a huge defense industry with multiple companies selling M14 clones, accessories and parts. The corruption is way worse and I doubt that anyone can clean it up now.

Jumping at every tender & trying to customize your offer for it can easily bankrupt a company in the long run.

The whole SCAR development was retarded from the start, with the US military barely meeting their stated promises to FN.

Frivolous bullshit like the development of the HAMR takes some serious R&D, and to then have the contract go to a rifle which didn't even try to meet the stated requirements is a huge slap in the face. FN-H could've just entered a beefed up SCAR instead of developing the HAMR to meet the automatic closed to open bolt requirement.

Then you have stuff like the P90 being cockblocked by German politicians to help save face for HK and ensure that the MP7 still had a shot at future contracts was insulting.

Not like it didn't bite the USMC in the ass when the M27's magwell was too tight for gen2 Pmags and nearly got all of them banned. But I suppose watering down the requirements so that FN wouldn't automatically win was fair... to everyone but FN.

Other than that I've seen a couple of unsubstantiated rumors about FN's entry.

1) FN felt the base SCAR on its own was good enough, but the HAMR was made to meet the original requirement for open bolt capability. The current M27 would have been disqualified.

2) FN's IAR grip broke off. Originally FN made it so standard AR grips could be used on the early SCARs.

However, this was a mistake as 1:1 polymer ≠ aluminum like the vast majority of AR lowers are.

This is the real reason why the grip tangs of later SCARs are thicker and why grips meant for the AR need to be modified to fit... or so the story goes.

Agreed. While there are 5.56 loadings that can punch through most armor, the same concept can be applied to .308 for even greater results. I think the reliance on suppressive fire and air support is short sighted and won't be nearly as effective if we engage in a more symmetrical conflict. If troops aren't able to accurately put rounds on target and put down enemies the answer isn't more bullets, it's more training.

LOl No. Space suits weigh hundreds of pounds. No earths gravity means not having to constantly use energy to keep yourself from falling down. No atmosphere means no drag when having to move and pressure pressing against you at all times.
The only downside would be that it take more energy and be harder to slow down if you wanted to but it would also take less to make you move.

I think we've reached peak delusion from the macho retard crowd.

Hate to break it to you, Juanito, but this isn't the Army replacing 5.56. They're only buying 50,000 of whatever wins, assuming the trials don't get cancelled like 90% of US Small Arms trials do. This is just there to supplement 5.56 in certain squads operating in certain areas.

Welcome to the logic of US military procurement and German shitheeling.

France and Britain wanted .280 or some similar calibre due to totally different combat experiences and knowing 5.56 wouldn't allow them to drop the heavy ass support weapons.

Jump to today and the US is looking to adopt ANOTHER 7.62 rifle for some reason instead of just adopting .280 etc as the primary round and then keeping a DMR.

But we can have this conversation in 20 years again when NATO wonders why their new rifles now lack the capacity for effective city fighting when we invade Beijing or Delhi or Laos.

Almost as if it'd be better to just have listened to the actual infantry focused nations back in the 70s.
>>
>>34773736
HK does not have enough resources to suck enough dicks to get the HK-416 approved. Even IF the Generals sign off on it Congress still has to approve it which will never happen given the insane price tag it has. Even the overpriced Colt M4's we buy are still one 3rd or less the price of HK's bullshit product.
>>
>>34775895
what on earth could have possibly convinced you the m82 was even in the same ballpark of being considered to be trialed?
>>
>>34775908
Yeah but it doesn't take a lot to move them now does it? And the reason they suck to move around in is because of the bulk not weight.
Are you retarded? If there's an atmosphere then there's some drag and then there's also pressure(do you know the definition of that word?) which means the atmosphere exerts a force down on you making it take more energy for your muscles to move you.

Italian guns were in service for decades and are now being replaced with another foreign design. I believe tooling to make M82 have been destroyed long time ago so just making it in US of A should not be biggie

I think a 6.5 would be better, with a 140 gain bullet weight with half of that being hardened steel and the other half hard cast lead with a steel jacket with a hardness of 80 brinell. Have it go 2650 fps from a 18 inch barrel.

does this mean that 7.62 will be as cheap as 5.56 when this happens?
>>
>>34776027
The hardened steel wouldn't be touching the rifling and standard steel jackets are 120 brinell.
The reason for 80 is to have better accuracy but to also have less wee than standard steel jackets.
>>
>>34775885
There is already one M249 per fire team and they have an effective range against point targets of 700 meters. Also, neither the M203 nor the M320 has an effective range of over 400 meters.
>>
>>34776027
I also forgot to add that the projectile should also have a small air pocket at the tip. Also since it will be back heavy that will itself be enough to achieve tumbling.
So this would tumble easily in flesh and pierce hard body armory and barriers while also having a bc of a least .5 so it is also good for long distance.

.308 is outdated, especially for combat. 6.5 is just as lethal to humans, but shoots farther, flatter, is lighter and kicks less.

Yeah but the Brinell of Copper jackets is only 35. Wears the barrel a lot slower.

Why hasn't there been a new, viable intermediate cartridge like 50 fucking years?
>>
>>34776301
There is plenty but they're mostly wildcats.
>>
>>34776264
Pretty sure it's 40 but even so 80 isn't that much more.
120 is for regular steel jackets and that decreases barrel life by half so clearly it's not linear in its effect. Another thing my rifle would have both melonite treatment and chrome(or something else that's better) and it would have polygonal rifling. Actual polygonal rifling not what Glock has with a very distinct hexagonal shape). This would further increase barrel life but also increase accuracy and fps.
>>
>>34776089
No, at thisbrate it's just the rising cost of brass and lead not being smelted anymore
>>
>>34776301
>Why hasn't there been a new, viable intermediate cartridge like 50 fucking years?

Because ammo design has pretty much peaked and reached a plateau. It's probably not the best ammo tech is about as good as it's going to get.
>>
>>34776324

I'm curious, how do they get the brinell of steel jackets down to just 80 when the brinell of regular mild steel (about as soft as you can get for steel) is 120?

Because the constant reality of how battles are fought combined with what is technologically feasible leads to a small range of options that are objectively the best, and once you have settled on one of those options it will take a significant change in how battles are fought or what is technologically feasible to justify the costs of changing to a different option. You also have to consider how little of an effect on overall squad performance a small change in what cartridge is issued would likely have vs other things that money could be spent on improving instead. The LSAT program seems to be the first recent attempt that may actually produce a new viable intermediate cartridge for military use.

>>34776409
Probably an alloy. Maybe steel and zinc or steel and copper or whatever metallurgists come up with.

>additional money, time, R&D dedicated to a cartridge that isn't caseless, is more complicated to manufacture, and doesn't even exist yet
USMIL wouldnt give the sales pitch 30 seconds

here's an idea, most of whatever you said, except projectile dia is 1.5mm too narrow and steel jacket is a regular hardness.
For finishing, projectile is wrapped/dipped in copper until its too thick, then swaged down til its balanced right and matches spec.
but wait, thats how bullets are already made. turns out you go the rifling in place, and subsonic 5.56 is jacketed 22lr
>>
>>34776725
pls stop. Unfucked FALs are bad enough.
>>
>>34776754
Yeah
It would cost millions to figure out an alloy with an 80 brinell hardness.
That is fucking retarded. I bet such an alloy already exists and i bet it's a steel and copper alloy. This wouldn't cost anymore money than if the us waned to switch to a different cartridge like 7mm magnum for whatever reason. It's no different and complex than what we already use.
>>
>>34775842
How am I wrong. If current techniques rely on air strikes or artillery coupled with suppression, won't a conventional war where our plans are being engaged by enemy planes and our artillery is being taken out potentially leave the soldiers on the ground on their own? If they're on their own with underpowered weapons geared towards suppression against an enemy with more powerful weapons, they'll be at a disadvantage, right? I know 5.56 can penetrate armor, but it doesn't have stellar terminal ballistics after having passed through a rifle plate. If I'm wrong I'd appreciate if someone could tell me why.
>>
>>34776957
so to sum up your idea
>polygonal rifled, melonited barrel
ok I like it, should also make it a progressive twist for maximum cool
>with chrome
what? like chrome chamber?
>6.5mm projectile
no arguments here
>overly hard jacket made of some as-of-yet-unnamed soft steel alloy
you are literally suggesting shoving a hard round peg with a higher coefficient of friction through a square hole at supersonic speeds. this will murder barrel life like a .260 in a regular not special barrel

youre almost headed in the right direction, but seriously, why the steel/alloy jacket? why not oiled phosphor bronze ffs
>>
>>34777251
No, the barrel is both melonite treated and chrome lined(if possible) or use a different process for chrome or melonite that's even better.
Polygonal rifle has exceptionally better life than regular rifling and regular rifling already stands up to normal steel jackets that are HARDER than what I'm proposing. Also if the jacket makes it more accurate and a soldier uses less rounds than the effective statisticial barrel life is the same. I mean it won't be since it won't be twice as accurate but 30 percent isn't out of reach.
>>
>>34777355
>No, the barrel is both melonite treated and chrome lined(if possible)
zero point. afaik, chrome lining won't stick to a melonited surface.
> or use a different process for chrome or melonite that's even better.
I'd have to find the document again of Nitriding process comparisons between against salt bath, Ion/plasma, and gas, but I think Ion/plasma nitriding would be the best.
>regular rifling already stands up to normal steel jackets that are HARDER than what I'm proposing
sauce. But if you post a fucking artillery barrel I'm writing you off

>Also if the jacket makes it more accurate and a soldier uses less rounds than the effective statisticial barrel life is the same. I mean it won't be since it won't be twice as accurate but 30 percent isn't out of reach.

I don't even know where to begin with that statement, except to say that it doesnt answer my question
