Kalantak: Possibly undergoing trials, no news.
Excalibur: Army rejected it without trials, as the Excalibur was an independent venture, which they did without consulting the army. As such it lacked stuff like Carrying Handle, and had stuff which army didn't want, like full auto. So it's been denied.
MINSAS: It failed as it overheated too much during trials.
INSAS Multi cal? I think you're talking about F-INSAS multi cal.
MSMC, undergoing user trials, most likely to pass the trials.
Amogh also overheats too much, but they are improving it, since they keep displaying new versions at Defexpo.
Trichy Assault Rifle is to be in service with the paramilitary.
Pathetic copy of AK-47 by Kanpur? I never heard of it. Are you talking about A-7?
Ordnance Factory Board
Th A-7 has been seen with some Indian troops in pictures.
