You have been hired by the United States Army ARL Weapons and Materials Research Directorate to perfect the standard issue combat rifle, removing and problematic features, issues, and general failures when it was designed. They give you a month before they begin to re issue your version of the M16A5 rifle. What changes would you make?
>Gas Piston
>Remove Forward Assist
>Side charging
Chamber it for 6.8 special
>>28269678
Fuck the gas piston meme, and fuck you for fucking up the sealed system.
I'd add to, not replace, the full auto fiction with a delayed recoil 3 rnd burst, make the mags more reliable, and make the barrel as stable as I could.
I might mess with the trigger group a little, but really it's fine for now
>>28269730
Lol do you know anything except memes?
>>28269750
Nice response
>>28269678
I would just issue new full auto Knowvacheck AR-15s to all soldiers.
Russia would surrender the following day.
>>28269730
Because nothing is more practical than having all of the products of combustion shoot right back into the chamber and bcg. seems practical, no?

People like you are the reason god doesn't talk to us anymore
The M4A1 with a full auto trigger group is pretty much a rock solid standard issue rifle.
Sure, you could make small changes to things like the grip, stock, rail system, charging handle, etc, but the function of the weapon does not really change.
I could outright say that the HK416 14.5 with a VLTOR IMOD stock, M-LOK fore end, BCM ambi charging handle and Surefire Flash hider is the best weapon for our troops, but it's not feasible.

For the same reason SOCOM didn't start using them.

>>28269949
Because they are awkward weapons and really offer nothing over an M4A1 to the vast majority of soldiers
>>28269949
Not enough of an improvement to warrant a complete change of service rifle.
>>28269678
magnesium alloy receivers
well fitted moving parts (think butt stock and hand guards, removing rattle and parts movement when locked in place)
caliber change, to 6.5
100% ambi dexterous controls
additional charging handle that can be used separate from standard rear charging handle (would have both, with it being end user adjustable aka one person can have only the side charging, while another will have both, and a third will only have the rear charging handle)
monolithic upper receiver
fire control group to include safe-semi-burst(two rounds)-auto

>>28270131
Why Mlok compared to keymod? Not saying one is better, just curious on the pros and cons
>>28270142
Either or, I don't care. I think they're both good platforms. I like the ergonomics of a thin tube, and if you or someone else doesn't then there are any number of accessories to suite your tastes. Maybe they could use clothing allowance to purchase accessories, return furniture to the armorer, and then install their own stuff.
Just make it 12" free float and keep the direct impingement. Get rid of pressure on the barrel.
>>28269678
>remove the forward assist
why?
OP, all 3 of your suggestions suck
The ar15 was designed with the stoner gas internal piston in mind. There is no piston system on the market right now that can out do "di" on an ar15
Side chargers aren't ambi like the current system
Forward assist is something used by soldiers and part of our manual of arms, fuck you for wanting to remove it
>>28269699
Moron. Shit performance past 400 meters. Afghanistan proved we need that capability
>>28269786
Ignoring the fact that the stuff shot back is non corrosive, the fact the filthy 14 exists proves that di is reliable.
>>28269822
Have ever heard of paying for the pony cock breath? Colt 6920s over priced?
>>28270087
Mg Alloy heats up quicker, bad choice
Also all this user configurable stuff does not belong on a service rifle
Tuneable trigger? Retarded. Everyone would put it on the lightest setting. Save money, make a good 5 pound trigger
Finally, safe semi auto. Double taps is what's currently trained and what would be used. Less mechanical complexity. And with the lighter trigger, double taps are easier and faster
>>28270131
>>28270142
Mlok and keymod are both pretty similar and honestly one is as good as the other. Mlok has qd stuff now, but keymod is a stronger and more secure surface to mount to.
Your upgrade is the most reasonable and realistic yet. Look up the m4a1 plus proposal. It's what I agree with to be the next step in our service rifle.
Finally, flash hider, no brakes. Soldiers in this day and age do lots of interiors, and brakes suck to shoot indoors.
>>28270249
I think that's what I was trying to pull from. What else did they want? IIRC it was a nicer trigger and something else.

Mlok requires less machining operations to make the slots than keymod and is therefore cheaper to manufacture, it's also compatible with plastic hand guards.

I know civilians hardly ever use them, but seriously, forward assist is essential, you can't palm it home like an ak.
>>28270306
So is keymod, b5 systems has a keymod handguard.
Generally speaking, you can get a thinner rail from keymod too.
But again, both a pretty damn good, best modular systems yet
As for your idea,

Other than that, a fine idea
>>28270403
Yeah that. FH instead of brake. Also ambi please because it was annoying as fuck shooting in basic as a lefty.
Read through whole thread. Honestly can't believe all the nit picking. Not enough research/ development is going towards optics and sighting systems. You guys can bitch and complain about the firearms mechanical parts all day, but they really are fine, and get the job done. They HAVE gotten the job done for a long time now. But yet most troops don't have proper optics.
B.A.D. Levers for everyone!!!!!!!!!!!
>>28270488
ACOG and Aimpoint
Done
>>28270499
Yas
>>28269911
No, I was talking about MLP.
>>28270306
Forgot one thing, stay with 5.56 for the polymer cased ammunition unless recent advances in bullet design have made it possible for a smaller caliber to perform equal or better to 5.56 from a 14.5" barrel when that smaller caliber is fired from a 20" barrel.
>>28270403
>the 5.7 pistol's grip is long and uncomfortable, inside the pistol grip magazine won't work
Would be less of a problem on a rifle.
>if this ammunition has similar ballistic performance to 5.56, 20 inches unneeded and all these different models fuck with logistics, just have a mid length one
5.56 has better terminal performance at longer distances when fired from a longer barrel as it fragmenting is dependent on the bullet's velocity, see pic related. Ideally general issue would be the 20" version as it would be about the same length as the current M4 carbine and the PDW version for wherever an M4 size gun wouldn't work the best, skipping the midsize version completely.
>If its not a bullpup, why does it have to be downward ejecting, as a lefty, shooting ars has never been difficult and the ejecting brass is a non issue.
Due to the push through feeding mechanism and the gun feeding backwards out of the magazine, it would eject about 2" behind the magazine as the LSAT design has the chamber separate from the barrel and round being fed out of the magazine into the chamber pushes the previously fired round out the other side.
>>28270419
Again, I'm lefty, and I've had no problem shooting m4s. I adapted to the rifle
Ambi selector would be the only thing that's be really nice to have.
>>28270488
But they do.
Aimpoints kick ass
Acogs and eclans kick ass
Low power variables are constantly improving.
Thermals are now and for the foreseeable future, situational optics not for every weapon.
>>28269678
you gain nothing by removing the forward assist but lose relatively large. just leave it
>>28269678
Just fuck my AR up edition?
>>28270550
That's with m193 that 20 inches is essential
When using m855a1, or mk262 ammunition, they're designed for 14.5 and 18 inch barrels respectively.
The shorter length is worth the trade offs in velocity.
That loading system sounds complex. If i understand correctly, the gun would still feed even if the magazine was loaded backwards why not have soldiers just load the magazine the right way, like they're already trained to do?
![G11_2[1].gif](https://i.imgur.com/G4UCIhI.gif "G11_2[1].gif")

All guns do this. Including single-shots.
>bcg
Non-issue, since there's exactly 1 moving part that requires literally thousands of rounds to gum up to the point of impeding action
>>28270488
Digital rifle scopes would offer a huge advantage. Using digital zoom over optical zoom would allow for zero parallax at any magnification, large ranges of magnification with little to no added weight, 1-20x scopes could be general issue, unlimited eye relief at any magnification, and a moveable eyepiece for comfort without having to move the whole scope and rezero it. They could be set up to be modular so FLIR, night vision, and laser rangefinder (or the LIDAR windspeed reader that DARPA is working on that can read the wind speed at multiple points between you and the target) components could be added depending on what the soldier needs. The scope could also have a feature like the Trackingpoint rifle/scope that could be turned on and off to allow less skilled soldiers to take precise shots at longer ranges if necessary.

See the beginning of my post here >>28270550 about what I forgot to include in my first post
>the gun would still feed even if the magazine was loaded backwards
Do soldiers have a problem loading current magazines backwards?
>why not have soldiers just load the magazine the right way, like they're already trained to do?
You still load the magazines with the pointy end of the bullet facing the front. The advantage is having a barrel a few inches longer without going to a bullpup design. The feeding mechanism also eliminates the problems of stovepipes, double feeds due to extractor issues, extractor issues in general, and stuck cases can be removed by simply removing the magazine and pulling back on the charging handle.
>>28270698
>do soldiers have a problem loading current mags backwards?
Only the female ones.
>>28270660
I'm so glad you're not actually working on a replacement project.

It was actually designed around the 10.3" mk18, because literally everything else Geneva/Hague compliant fucking sucked out of shortys.

>fragments within 200m
Yeah, when fired from a 20" barrel, and it drops to about 130 meters when fired from a 14.5" barrel, see the chart here >>28270550, there's no reason to shorten the barrel of the M4 by 2".

>>28270841
Let me rephrase.

>>28270852
usgi mags with the latest followers(tan or orange) are perfect.
>>28270866
Sounds good. In that case destroy or sell all the old shit so nobody gets stuck with it
>>28269678
Develop a new cartridge that bridges the gap between the 5.56 and 7.62. This becomes the new standard round for LMGs, Carbines, DMRs and Assault Rifles. Aim for a caliber of exactly 6.35x48mm. 6.25x49mm is also acceptable. Call it the .250 American. Muzzle velocity should be at least 800 m/s when fired out of a 14 in. barrel. Of course, the actual new rifle will have an 18 in. barrel. We will just do the testing out of a 14 in. barrel to account for the inevitability that a carbine variant will be made. 18 in. will be standard barrel length. The emphasis here is on providing superior penetration and long-range accuracy in comparison to the 5.56 while still having a round small enough to be an assault rifle cartridge and be controllable enough for full-auto.
In terms of mechanics and appearance, just imagine a SIG MXC with an adjustable stock, an 18 in. barrel, and a .250 chambering. No burst fire. The only modes are safe, single-shot, and full-auto. Proper training obviates the need for burst-fire.
>>28270698
Thank you for clarifying.
That does sound cool and rids us of lots problems, but doesn't it introduce new ones? Mainly with ejection and increased number of small parts?
As for digital scopes, I still think that technology is years off. Current stuff is huge and battery hogs
>>28270904
black followers, the original ones, are prone to tilting
green followers, are still prone to tilting.
I've never had a tan or orange follower mag cause a stoppage.

>>28270817

M855a1 was designed for 14.5

Don't think it would add to many more small parts, from what I understand it has something to block the round being fed from being ejected, but I don't think there's to much else.

True, but the idea of a single scope that can do everything effectively would be great.
>>28270741
No because your first order of business was to remove the forward assist, you clod.

WAR and adjustable gas block is a redundancy, don't even say "quick adjustment and find tuning" because a military rifle doesnt give a shit about your super precise ejection patterns.
Furthermore, only socom uses cans and not often, so adjustable gas block shit is even less messecary
Again, worrying about the buffer spring is autistic ejection patterns bullshit
Finally, the super semi automatic cannot be used to shoot burst or full auto and does not belong in a military rifle

The marines I've talked to who have used the M27 or have had it in their unit have said it's only real advantage over a M16 is that it has a FA fire mode. Reliability is a little better than the m16, but it still has over heating issues.
