It seems all the talk about India joining the US Army LSAT program under the DTTI is actually going somewhere. From the sound of it it looks like the gun will not be a direct import from Textron but rather a modified MCIWS rifle. I do hope DRDO-ARDE can learn a thing or two about rifle ergonomics design :

Why long stroke piston ? I thought short stroke was better. What mechanism does the Textron prototypes use ?
This is the carbine prototype from Textron :

This of course is the MCIWS first prototype:

Prototype design from around 2015-16, notice the modified front handguard region and shorter barrel. Still no complete rail on top, that came more recently :

Butt folding mechanism similar to a SCAR at a later design, signifying the removal of AR type buffer tube :

Firing mechanism :
Notice how the BCG closely resembles a AR BCG, same with the trigger group.
Also I thought the Caracal carbine deal was scrapped. Is it still on ? Any updates on that ?
Thing is, if at all we're intent on following in the US Army's footsteps (which it doesn't really look like we are), then it would serve to strike up a partnership with whoever ultimately wins NGSW.
Textron is only one of the three competitors, each with their own rifle and own ammo tech (General Dynamics is offering fully polymer-cased ammo whereas SIG is offering a hybrid 6.8x51mm round with a steel base mated with the brass). If at all we choose to go ahead with what Textron is offering, and either SIG or GD end up winning NGSW, we risk being stuck at a technological dead-end in terms of what can be brought to the table from the US.
SIG NGSW-R offer:
SIG hybrid ammo:
General Dynamics NGSW-R offer (bullpup):
GD's polymer-cased ammo (collaboration with TrueVelocity):
Personally, I feel that perhaps SIG's offer is the most practical among the three NGSW competitors...partly because their ammo ensures that all the manufacturing infrastructure that's built up & existing as of today doesn't have to undergo significant changes to their production process, incurring substantial cost-savings...and this has to factor into what the US Army finally selects (remember, they might yet again just say screw this and throw NGSW out of the window as happened with multiple programs in the past like HK XM8 or LSAT).
Also, it does appear, at least at first glance of the exterior that both SIG's and GD's offers are at a far more refined stage of design than the admittedly awkward (if you ask me, UGLY)-looking Textron rifle.
Regardless, IA should learn to create a requirement after careful deliberation and study, and just stick with it. The Americans are already sitting on an excellent platform in the M4 which seems to be infinitely upgradable/modifiable so its not such an issue for them if the replacement takes longer to arrive. We don't have this luxury.
And I'm of the firm belief (now more than ever) that getting a GOOD rifle in the hands of the infantryman ASAP is far more productive & important right now than having a
supposedly EXCELLENT rifle on the drawing board which may or may not be realized 10 years from now.
As of CAR-816 deal, it's fallen through and the carbine tender (fast-track) is back to square one for all intents & purposes it seems like.
