Arjun MK1A. Only if we can get rid of it's rifled gun for good & put a 125mm smoothbore there. it will be a completed massacre at international border to our west.
so finally you accept that even Arjun MK1 has better frontal protection than leopard 2a4.
of course the newer leopards have L55 instead of previously L44. which can fire better rounds with 750mm or greater pen at 2km

Why we went for 120 mm is beyond me , all other tanks have 125 smoothbore .
That piece of junk zarrar also has 125 mm gun.
Such a beautiful tank brought down by due to gun

Does anyone else in the world make single piece 125mm ammunition? Do you think OFB can always be trusted to maintain proper QC and regular supply? It wouldn’t make any sense cuz all the other Indian tanks use 2 piece 125mm tank ammunition. So 120mm and 125mm single piece wouldn’t make any difference from logostics point of view. The OFB 120mm ammo is just a upsized version of the ammo DRDO developed for the the original 105mm gun and possibly is the reason why FSAPDS 120MM MK1 was so poor.

maybe because it has its derivations from british L7 105 mm gun used on vijayanta. and russia wouldn't give 125mm gun TOT.
so DRDO might have studied the 105mm rifled gun and made a 120mm rifled gun.
because L7 was also manufactured in India. so OFB had the tech for 105mm gun.

arjun MK1 with L7 105 mm made to go against M1 abrams with L7 105mm. both had same gun. and similar effective armour thickness.

yes. the FSAPDS MK1 penetrator was actually made for 105mm gun. so ~ 300mm pen at 2km is actually decent for a 105mm gun . even abrams M1 with 105 mm gun fired apfsds with 310mm pen at 2km.

OFB used the same penetrator and fit it into discarding sabots of 120mm total diameter.

You realize the life of Arjun gun is double that of Indian T90s
...And can fire twice the variety of shells, while all tanks in our sub-continent has equally shitty 500-550mm rated FSAPDS.

No noisy people don't realise that much. Just look how random & pointless the comment is, of the other guy too. Most chaps usually know what they've been spoon-fed from a few YT videos, not actually spent time acquiring information in details.

Then why it is criticised ? comrades answer my one more query .
If DRDO can make such a ingenious 120 mm rifled gun , then why not a 125 mm gun ?
Do we really need tot from Russia or does metallurgy plays such a great role in the manufacturing of a tanks gun that , just because it's caliber is changed , the gun may be affected positively or negatively ?

Well , I don't know about any other source to acquire information sirJi.
Lots of people criticise arjun for its gun , saying it's underpowered etc

Yeah that's what I said... But the fact is all tank-guns in the twin are equally underperforming & Arjun's 120mm holds the above mentioned advantages.

Apparently one was under development, but no news on this front for a long time. Maybe next Defexpo... Anyways 125mm Hill no advantage one 120mm only problems, like it'll need a bustle autoloader. So we had no reason to change. A 120mm smoothbore should have been imported & indigenised to save time.

Just read this thread only.

What are the protection level of Arjun MK1A? as for rifled gun advantage there are limits to how much chamber pressure can be increase without fcking life of barrel due to rifling.reduce muzzle velocity will be another problem. spin drift of rounds & spin induced ricochet off armour due to rifling induced round spin is another problem.
