How long until the sigger rifle gets dropped entirely?
So now they lose the range advantage the M7 had?
We are going to end up with M4s and AR10s shooting ultra high pressure NATO calibers, which is the best move anyways.
Fun times. Can't imagine how many times you can shorten a battle rifle's barrel before you start seeing significant impacts on velocity and energy... which this whole program was intended to improve over the M4A1...Really starting to think if they wanted extra firepower that bad they should have just resurrected the M16A5 and called it a day.

>>65246471The "rifle" only had a 13.5" barrel to begin with.
>>65246602It's not even about the trigger at this point. If a new rifle doesn't present the exact operating order as the M4, they don't want it. You could give them a fucking lasgun and they'd still go "Where's the forward assist?"
>>65246551unironically a better choice than Sigshit
>>65246636how retarded are grunts that learning a new manual of arms is impossible for them?
>>65246676It's more that big army is unwilling to go through the complicated bureaucratic process of making slight changes to official instruction procedures. Except for the ones that make absolutely no sense or increase misery of course.

>>65246712You dumb motherfucker.
>>65246629Seriously what the fuck is wrong with the army? When did this short barrel mental illness take over, when it was readily understood that anything under 14.5 was impractical for non-specialized doorkicker applications, and soldiers did just fine with 20+ inches for decades?>muh weightYou bought a heavier rifle with heavier ammo and a heavier logisitical train in every sense.>muh lengthYou cant use your gun without a suppressor. You can't even grip an SBR properly because it's so short.>muh suppressorsThey make them shorter now. And if you have more barrel you get less muzzle blast, and if you want range and armor piercing overmatch its gonna be supersonic anyway.>muh armor piercing capabilityMake and hand out more black tips. If a black tip can't kill it use a grenade launcher or drone.
>>65247061The point is to suppress every rifle without making them pike length.If your suppressor is 5 inches long, then your barrel has to be 3-5 inches shorter to avoid excessive length.
>>65247061>You cant use your gun without a suppressorthe gun is nigh unusable without it. it is incredibly concussive.
>>65246398Is it so hard to make a simple bullet tube? When the slavs want a new weapon they make the barrel wider on the AK47.
>>65246478>overmatchorwellian nonsense word. just say surpass.
>>65247061>When did this short barrel mental illness take over,GWOT and the SOCOM disease becoming something that the bugchasers in the pentagon wanted to infect themselves with
>>65246835Same reason the original M5 designation was dropped in favour of M7, because Colt own the trademark for "M5"LWRC owned the "M6" trademark
>>65247061>soldiers did just fine with 20+ inches for decades?Short barrels were always more popular with soldiers whenever the chance existed, all the way back to vietnam and korea. It was simply during GWOT when bureaucrats started listening to them.
>>65246398The correct answer is a 5-6mm C-T carbine effective to 400m, combined with MGs and airburst HE out to 800m and guided HE for anything past that.
>>65247346>Short barrels were alwaysNo, short *rifles*. 14.5 inch barrels are for faggots. M16 is far more effective and deadly than M4, but here we are everyone is issued the CAR. (Not to mention the OP nuSIG giga-atrocity)Mentalities, groupthink, overall culture, leads to these situations. Nothing to do with engineering, doing the actual job, or combat effectiveness.
>>65246398I really didn't want this to be true but this is going to end up being the smoothest adoption of a service rifle in a long time. Really didn't expect this from a company that puts the "automatic" in semi-automatic for their handguns.

I was gonna type out a whole paragraph on how fucking gay this whole situation is but I don't think I need to.
>>65246712You are comically dumb
>>65247586M16 is deadlier than an M4 combat or not. Small arms are irrelevant, indirect fire is the arbiter of warfare.
>>65247619>doubling down on zoomerloreSince small arms are irrelevant, you can carry a musket with a 40" barrel and a +10lb lead weight added to the stock.I had the option to choose between a musket and a M4 on my first deployment. The musket never left the armory.
>>65247635You do you. M16 is a deadlier firearm than the M4. (Different firearms can be more appropriate, suited to certain jobs—and in service of/wielded by particular users—than other firearms are)
>>65247650Look at some ballistics gels by ammo and impact velocity, retard-kun. There's nothing magical about unadjustable stocks or excess barrel lengths.
US soldiers can thank the ukrainian conflict for that.Why don't they just get hk416 like marines and french army.
>>65247664>muh barrel length stocksNot what any of this is about. Sniper rifles and DMRs exist. The M27 exists, and is now the entire USMC's standard rifle<--didn't start out that way.

>>65247575Its already been super rocky and there have already been QC issues with the M7. Its also about to become completely irrelevant as we pursue new alloy casings for 556 and other calibers we already use that weigh less and allow us to load the same rounds much hotter. I cannot conceive of a rockier start, especially when the this very thread is talking about a pretty significant modification to the rifle already when it literally just got adopted at all
>>65247069It's the opposite. If your barrel isn't that short, then the suppressor doesn't have to be that long. Mini suppressors don't suppress as much but if you're not engaging in a hopeless drag race trying to spit the bullet at acceptable speeds out of stupid fucking snub barrels then all that excess energy becomes speed instead of noise, flash and heat, so you can afford to have a less effective, less large and complex and expensive suppressor on a rifle that isn't that much longer.And you also don't beat your gun to death in the process for that matter, what's the life expectancy of an XM7? 50k rounds?
>>65247061>Seriously what the fuck is wrong with the army? When did this short barrel mental illness take over, when it was readily understood that anything under 14.5 was impractical for non-specialized doorkicker applications, and soldiers did just fine with 20+ inches for decades?Because the big conflict zones of the future have been predicted to be urban zones for the last 15 years. The guys upstairs think that everyone needs a short rifle because they're going to be having gun fights in stairwells and alleyways.
>>65247812have fun with your long rifle in a trench
>>65247820if you are having trouble with a 20 inch rifle in a trench, then I think you may genuinely be retarded.
>>65247807>50k roundslol, lmao. It would be lucky to see 10k rounds. Especially now with the skeletonized BCGs they are using on the M8. This thing is ONLY going to have maintenance problems
>>6524765011b in the US Army (Afghanistan, Iraq) to YPG anon in Syria to MMC anon in Syria to TDF infantry anon in Ukraine to drone anon in Ukraine here.Not a single time, ever, even once, did I think "Geez, I sure wish this barrel was 5 1/2 inches longer, that sure would be helpful right now".Not sitting in a trench, not doing MOUT, not taking pot shots at retards across a valley, not in training, not even on a flat range, never. Never once. The amount of annoyance from the length alone just walking around with it slung in thick brush is not worth the marginal ballistics gains.>>65247741Go take a 20" rifle and walk through some shitty brush with it for a day or two, then do the same with a 14.5". Go practice clearing a room with it. Practice clearing a 24" wide trench with it (or just restrict your hallway in your suburban home with some boxes or some shit).>>65247834Trenches get ridiculously tight, so tight you can't fit two men side by side. So tight you can barely fit yourself in kit sometimes, let alone with your rifle and all the other bullshit you ferry up and down the lines during an assault. IDK what the fuck is up with you niggers acting like war is always (ever, even once) going to be some pretty sanitized open hallway you can practice a rolling T in or some shit.>>65246398The entire program is just wasting time when we could have just marginally upgraded the M4A1 inventory. Every single dollar we have put into small arms should have been allocated for optics and NODs in the past 15 years anyway.
>>65247965I would like to ask if you've ever held a designated marksman role or similar, not disagreeing with your sentiment at all but your answer could give us some extra perspective.I'm not even a big fan of the M4/M16 platform but it was obviously the wrong choice to go with the Sig offering. The GD option was superior at the time but I feel like the war in Ukraine has made it clear that battle rifles cannot be the standard for riflemen now, since shooting down drones with rifles is such a concern for infantry and volume of fire has proven to be very important (and because 5.56 and 5.45 have both proven to be effective against drones of all sorts). We don't really ever see footage of it, but do you ever find your drone surviving after taking a hit from a rifle?And then of course, as the anti-drone infantry meta evolves, it increasingly seems like cqb is the one place where they're not going to help much, which is yet another point in favor of a 5.56 carbine.Makes me wonder if 9mm or 5.7 or 4.6 SMGs will swing back around into the meta. Being able to carry an absolute fuckton of rounds compared to 5.56 is a big advantage, and unless you have tungsten core in every single one of those rounds, they're not going to be any better against armor.
>>65247965>11b>did I think ___ , ___ , ___ , never once ___ not worthThanks for the anecdote.
>>65246398>XM8Are they reusing the same designation for a different rifle or is this the straight up original XM8 they skipped over after it fit all their demands including looking futuristic?
>>65248033(NTA) in this case the anecdote is highly relevant because it adds real-world context to an otherwise technical and detached argument (ballistic gel performance, muzzle velocity, etc). On-paper expectations do not always match field performance.
>>65247735Good pic

>>65247228It's not Orwellian in the slightest. It is in fact, very Germanic.
>>65248161it's orwellian in that it is a nonsense word that everyone has to use because of bureucracy. either you match or go over, in which case you surpass. It is an act of doublethink to seriously say a word that means nonsense.
>>65246602Make it electronic.
>>65249126"the ministry of production overmatched their quotas. we congratulate them for beating their quarterly objectives, for which they will suffer a demerit for just meeting the standard and not going beyond"
>>65246407No, they had reduced the pressure to reduce recoil and now they're increasing it again. Also the carbine is lighter so that's going to increase recoil as well.
>>65247580whose fault is it? EVERY TIME
>>65246495Yes
>>65246398>keep finding ways to shorten it when you could have just had a full length bullpup with no cons from the startGuys, are bullpups really that bad?>>65246629It was always a carbine, hence why it started as the M5 (after the M4), rather than M17 (after the M16)

>>65249325No, but the RM277 really was that bad.
>>65246593Such a (((br*tish))) concept like the bullpup is unsuitable for the brave, freedom-loving men of our armed forces. I say we go back to modernizing the m16a2.
>>65246398The great satan strikes again…
>>65250372Garand Thumb tested this. He said it's the most effective suppressor he's tested, at least from a signature reduction standpoint. It gets hot very fast, though.
>>65250874I think the mirage problem is a non starter for it especially on anything that isnt a mk18 with a red dot anything magnified is no go. I heard rumors of less than 10 rounds on a 338 or similar sniper and its unusable
>>65250944Wow, that sucks. They should probably incorporate the techniques used by Ambient Arms on their self cooling suppressor.
>>65247069Then get a chode suppressor. Either the potato we saw in the NGSW, something like the YHM fat cat, or there’s an even shorter 2” one for 5.56 that I’m blanking on who makes it. The latter obviously isn’t hearing safe but it takes the edge off. The 6.8 with a suppressor isn’t hearing safe either, so if you’re using ear pro already you’re fine with a short, less functional suppressor. Also a 14-16” barrel, with a 4-5” suppressor isn’t “pike length”.
>>65246712fucking kek
Would someone in Ordnance please explain why chopping the barrel on the M7 a couple of inches necessitated an entire new M designation but a tank with an entirely new engine, completely redesigned interior, fire control system, and a remote turret is still an M1?
>>65246835>M7 Carbine>Needs M8 Carbine-erI don't like it
>>65248033>NOOO YOU HAVE TO HAVE MY HECKIN BASEDERINO LONGER RIFLES! YOU HAVE TOOOO!Your opinion is based on nonsense that you haven't even experienced. Shit, show me a guy who gets shot with an M4 that survived but magically wouldn't have with an M16 lmao, and then manage to convince me that this absolute unicorn scenario outweighs the benefits of a carbine. What if you didn't have breakfast this morning?>>65248009Qualified on the M110 and carried it around for a bit, but we relegated them to the platoon that stayed back on tower guard 99% of the time. I simply believe they do not currently have a place in warfare; snipers are starting to be replaced with FPV teams. If I am slinging lead from a distance that warrants precise 7.62 from a concealed position, I can take cover and sling a drone your way instead, more accurately and with much greater impact.>We don't really ever see footage of it, but do you ever find your drone surviving after taking a hit from a rifle?Never had a mobik even manage to aim at a drone from my end, let alone get accurate shots off. This is mostly because I was rarely chasing infantrymen; I am sending an FPV into dead space like bunkers or random dugouts, or hitting vehicles or antenna. If you see an infantryman killed by an FPV it is to repel an assault/buy time for your guys, or because your battery was about to die anyway and you might as well instead of waste it on the ground. Even though FPVs are comparatively cheap, much better to try and destroy material with them than a replaceable grunt.I have seen video footage and feeds of FPVs being shot though; a lot of the time the inertia of the drone will manage to finish the job either way by the time the infantryman on the ground manages to hit it. Shotguns are better than rifles for this if you have anything approaching the right load.

They explained that no matter how good a shot you are, it's a moving target at an odd angle, moving quickly and potentially erratically, and often pretty far away. So, their strategy is to down them with sheer volume of fire, with multiple guys simultaneously taking rifle shots until it goes down.Anyway all that's to say, I just really have no idea if the russkies are doing something similar. Apparently not.

>>65254070>The US army won't buy a new high psi upper Yes they will >it'll buy a Federal PEAK style cartridge which gives +400fps without needing a new chamberHigh pressure 5.56 would either not be safe in existing chambers, or fatigue the barrels way too fast. Not to mention break the bolt lugs prematurely due to bolt thrust.>That way they can keep using their stockpile of old ammo.A high pressure 5.56 chamber (TBD) would accept normal 5.56What may happen is that some manufacturer can make a conversion kit that would be a bolt+barrel, that can be retroffited into an M4 upper. But at that point, there's really no reason to not buy a new upper with more bells and whistles.
>>65254660In an AR-15 the bolt is the weak point. The chamber, barrel, and barrel extension can handle higher presssures just fine. All you need is a stronger bolt and a gas system that is tuned for the higher pressures.

>>65254660>he doesn't knowThe whole point of Federal's PEAK is that it safely enables high pressures in existing chambers - that's why they are selling it to civilians in 6.5 creed.

>>65254826Notice how they aren't selling in 5.56, 7.62 or other legacy calibers The reason Federal is selling PEAK in 6.5 is because all those guns are of recent manufacture and can handle the higher pressures.
>>65254865>7.62x51 starts seeing adverse effects under 16"Because no one making 7.62x51 designs their powder burns for under 16"
>>65254337Not the point of that post (and see upthread from it). M4s are shitty.>lighterM4 is heavier than an M16. (And see upthread discussion, plus >>65248395)
