A little off topic but the Indian army is not alone in having issues with its primary small arms system.

The fate of the trouble G36 rifle has been revealed: German Defense Minister Ursula von der Leyen announced on Wednesday that the Bundeswehr would seek immediate replacement for the rifle. From DW.de:

Germany’s military will have to find a replacement for the current G36 assault rifle, according to Defense Minister Ursula von der Leyen. Special Forces troops are to receive new weapons immediately.
Germany’s military was likely to get a replacement for Heckler & Koch’s G36 rifles after Defense Minister Ursula von der Leyen declared on Wednesday that the weapon had “no future in the German army in its current state of construction.”
The Defense Ministry would now work towards replacing the gun as soon as possible, von der Leyen said after she met with representatives of the parliamentary Defense Commission in Berlin.
Immediate replacement for soldiers
Special Forces deployed in conflict areas were to receive replacement weapons immediately, the minister added. However, she did not exclude the possibility of the army adopting a new version of the G36, produced by weapons company Heckler & Koch.
Problems with the assault rifle would be discussed within the Defense Ministry and initially there would be no parliamentary commission to examine the ministry’s findings, opposition parties said in Berlin.
The Left and the Green parties would at some point in time question Interior Minister Thomas de Maiziere on the G36 affair. De Maiziere served as defense minister in 2010, when problems with the weapon first came to light.
Low accuracy at high temperatures
The assault rifle’s capabilities came under scrutiny after a study commissioned by the German Defense Ministry last year claimed “the weapons system did not fulfill the requirements.”
The weapon’s capacity to hit targets fell to 30 percent when the surrounding temperature reached 30 degrees Celsius (86 Fahrenheit) or when the weapon became hot through constant use, the report said.
The reason for the gun’s poor precision was its “complete system,” the research revealed.

Von der Leyen did not exclude the possibility that the next rifle could be from Heckler and Koch, nor even that it could be a variation of the G36 itself. However, the possibility of retrofit of older rifles -beyond re-using some mechanical components – seems distant; the Bundeswehr appears thoroughly dissatisfied with the weapon. - See more at: http://www.thefirearmblog.com/blog/2015 ... dnBUK.dpuf

Thanks for sharing estousandy!

This is indeed a very courageous step taken by Lt. Col. Deepak Malhotra - I applaud his action - BRAVO! :cheering:

Lt Col (retd) Deepak Malhotra, the petitioner, alleged that because of "bureaucratic red tape" soldiers are made to use a "clearly inferior weapon" at the "risk of losing their lives".

Can anyone help me with the trajectory chart of INSAS 5.56 rifle or let me know the Ballistic Coefficient ?

If they are using standard 5.56 x 45 NATO, all you need is the barrel length and you can get a close approximation of its trajectory by comparing it to other rifles firing the same ammo.
As far as the BC goes, it depends on the bullet that they are using. For example, Hornady's 55 gr. .224 FMJ-BT lead core projectile has a BC of .243.

The trajectory of a 55 gr FMJ bullet in .223/5.56X45 NATO, out of a 16" barrel, can be seen on the second post on this page.

If the INSAS does not use the same bullet, then you need the BC of the bullet and at the very least, the muzzle velocity of the bullet to make an approximation.

5.56 is great to take a human down nothing else in my opinion also check out green tip 5.56 ammo love them have box’s full of them but for a Russia style ak weapon they should of kept 7.62 that’s what it was made for 5.56 is a Ar style rifle m16 type my 5.56 also can run 223. that’s the one good thing about Ar plat from.

Reading this in 2018.
What a beautifully written and detailed analysis.

This rifle is what a rifle shouldn't be.

It's a shame we can't build a weapon of international standards in our country.
