This suggests that there might be a case for considering the use of rifle grenades instead. These are less accurate, but typically carry twice the HE load and avoid the need to carry a separate launcher.
I think this idea has a lot of merit in light of emerging optics technology.
The Army is looking to go from IR lasers to IR Laser with integral range finder:
Meanwhile, Matbock has come up with a simplified grenade launcher sight. The range to target is entered, and then the weapon is simply raised upward. When the right angle for the range is achieved, a light turns green, signifiing for a shooter to fire.
If the 'grenade launcher angle' feature of the matbock was added to the IR Laser range finder (seems like a pretty simple addition) then every soldier would essentially be equipped with a Grenade FCU for firing rifle grenades, with a minimal increase in bulk vs the current Ir laser sight + range finder.
The only problem I see - possibly insurmountable - is the switch to 100% suppressed use. At a minimum, this would require greatly expanding the diameter of rifle grenades to be able to slip over a suppressor.
I also imagine firing a RG with a 6.8 would result in pretty insane levels of recoil. Plus whether a bullet catch system could contain 6.8 AP.

All good points.
Recoil, in the end, is down to the mass of the RG and if you want less you just need to make them lighter, Old RG were quite heavy as they were initially meant for anti armor the non-overcaliber antipersonnel versions have tiny charge for given weight Only cca 70g of explosive for 500g grenade. The lighter grenade easier the bullet traps job ,There are walkarounds for absorbing the bullet by telescoping the trap and even by telescoping function compressing a secondary propellant that is discharged through the nozzles on the body but i don't think the RG is making comeback ,even tough it would make much more sense wen it comes to rifle launched drones or guided ammo.
The Grenade launcher is simply to entrenched ,and with 203 on the scrapheap the side opening ones can house longer payloads.
Altough when you look at PIKE its basicaly the size of a rifle grenade only constrained to fit the 40m Grenade launcher
This one looks like it uses missile seeker as aiming optic
Just need more trap material. Or a mag of blanks for grenade launching.

Or just a "pass-thru" grenade, like the old FN "Bullet Thru(R)" rifle grenade.
Interesting enough, this concept didn't catch up because it was nearly impossible to make a good HEDP.
If you read the rfi and know the backstory here you know that this is targeted for an American built xm25 redux (hk had to hand over the TDP) with a new revised optic based off either the fws cs fws i or the ngsar optic. Luckily the government owns basically all the IP for these options so it should be a straight up see who can build us x number of these for the best price and or something better.
The nicest part about that is the optics technology has gotten CHEAP in the years since this program stuttered out. (even the prototype STP ngsar optics are about $10k each for hand built low volume protos)
Also things like either ivas or envg b are already set up to interface with this and envg b runs $15k each while ivas prototypes are coming in at $10k each for the battalion set soldier touchpoints.
Between the DOD owning the IP and technology finally being of age to do this stuff in small cheap packages this is a program that should go fast.
I say should because we all know it probably won't, but on the surface very few of the usual roadblocks apply.
An HEDP grenade not designed in the 70's would be plenty lethal. There's been preliminary studies done on this already. As an added bonus they might cost less too.
Mr. T (MrT4) said:
downside is recoil.
I've had a chance to fire GM-94 this summer, although with Flash-bang rounds rather than HE/FAE. Recoil was not that bad, and certainly more bearable than that of the RMB-93 12 gauge shotgun which served as a starting point for design of the 43mm GL.
It is also pretty accurate, even with iron sights. I was able to land my 1st shot right at the feet of the target at 200 m.
I see that South Africa has purchased 40 mm MV grenade rounds from Rheinmetall.
The South African Army initiated the project in 2016 with the aim of fielding a new grenade launcher and family of 40mm ammunition. Armscor, the nation’s arms procurement agency, approved the procurement plan in February 2018, subsequently overseeing testing and evaluation of the Milkor Y4 multi-shot weapon. This involved firing Rheinmetall Denel Munition’s less-lethal, low-velocity and medium-velocity ammunition. Particular emphasis was placed on speed and accuracy.
The South African Army procured more than 20,000 rounds of medium-velocity ammunition, including high explosive ammunition, high explosive dual-purpose ammunition, practice ammunition, practice tracer ammunition, red phosphorous smoke rounds and orange target marker ammunition.
Rheinmetall Denel Munition’s medium-velocity ammunition has a maximum range of 800 metres, exceeding conventional extended range low-velocity (LV) variants by up to 375 metres while delivering unparalleled accuracy. The company’s ammunition suite currently encompasses nine different MV variants, six of which formed part of this procurement package.
With Rheinmetall Denel Munitions’s handover, Rheinmetall has taken the first step as the leading maker of new 40mm medium-velocity (MV, ca. 100 m/s) ammunition. The company is currently expanding its MV product. It now includes the new generation of 40mm MV ammunition, which has a maximum effective range of 800 metres, doubling the gunners’s operational reach and providing a flatter trajectory for those crucial close-in, accurately placed shots MV ammunition is. Currently undergoing NATO qualification, Rheinmetall’s 40mm MV ammunition family will soon be available in service and practice versions. It can be used with the multi-shot grenade launchers Milkor US M32A1 and AV 140. Furthermore, Rheinmetall’s 40mm Magazine-Fed Grenade Launcher (MFGL) is currently under development.
Does anyone know of any other countries which have adopted 40mm MV?
Also, does anyone have any details or illustrations of the MFGL?
