The rank and file liked 30 calibers they had previously.
Ah, but does it have a mix of metric AND non-metric screw threads scattered through the weapon like the Indian made FN-FAL rifles did.
Evidently they copied bits from the British license built version and the Belgian original in their own license built version. So the screw threads are not compatible with other models *consistently*
Or so I read many years ago.
ISTR that, even today, not all units of the Indian Army have 'modern' rifles and many were, until recently, still equipped with SMLEs! I presume these would not be frontline combat units, but back when the FN FAL was the service rifle it was certainly more prevalent even in some combat units.
A lot of Indian 'Security Services' (aka 'Police' of various sorts) are evidently also still equipped with SMLEs ... not the elite guys, but those that are merely a step up from a Beat Cop equivalent.
(Note: Even though I call them SMLEs and FN-FALs they were, after Independence, largely manufactured in India and have Indian designations, but are, in fact, lightly modified from the originals).
