Looks good tbh. Finally a replacement for the older uzis for Para. Might become as good as MP9 after MK2 and later versions. Simple blowback mechanism afterall.

@Noob @Mr.Evil what say?

It's beautiful already won one competition and will compete in any 9mm competition in the future their is no MK2 for now for Asmii but good to see less yahoodi guns in Indian army arsenal
 
I think NSG does that Sig-716 in G2 variant, which were procured earlier than the IA's deal of 72k Sig-716i variant.
The 716 G2 variant is heavier and was more costly than the 716i variant.

Indonesians use G2 Variant I don’t know if it’s DMR or CQB one
NSG indeed uses G2 variant procured before IA deal and even SG might be using G2 Variant which was also before IA deal happened my question was for 12.5 inches version compared to our 16 inch ones
 
Different Variants of SIG716
We use SIG716i & SIG716 G2 DMR
The other SIG716 that we have with NSG and few other SWATs are not the exact SIG716 G2 DMR.

Between SIG716 DMR Gen 1 (continuos pic rail) and SIG716 DMR Gen 2 (the pic you posted) there existed another "Gen 2" before it got discontinued; it had KeyMod mounting. After a while SIG completely ditched KeyMod in favour of M-Lok and also adopted an improved handguard mounting system (you can see two black retention tab near the barrel extension in the pic) and it became the current Gen 2 DMR.

When NGS got their hands then it was yet to be launched so we use the "older generation Gen 2" of SIG716 DMR
The 716 G2 variant is heavier and was more costly than the 716i variant.
Because only 716i uses DI as opposed to short stroke gas piston. Infact it was designed from ground up after IA explicitly asked as a bid to lower cost because before that there was no DI SIG716.

After delivery started SIG launched a civilian variant of SIG716i as SIG716i Tread.
 
Can anyone briefly explain different gun operating mechanisms like DI/short stroke/blowback with 1/2 popular examples?

@johny_baba must have written something somewhere about this. or has them in his notes.

• DI or Direct Impingement
There is no gas piston or gas cylinder; the gases directly impinges on the bolt face. Extremely simple but inefficient so only two three guns use them. MAS-49 is one example
Interestingly AR-10/15 is not a DI based gun
• Short Stroke
Gas is vented from the barrel to a piston assembly which then cycles the gun. What makes it "short" is the fact that the piston travels less than the distance of the cartridge. All modern assualt rifle are more or less SS; SCAR, Bren, MSBS Grot
• Long Stroke
Same as SS but here the gas piston travels the whole length of the bolt cycling. Almost all machine guns are Long Stroke, so are all AKs.
• Blowback
The only system that's "unlocked" meaning the bolt and barrel are not positively locked and are just together using either spring tension or some delaying mechanism. It's the simplest as it works on action-reaction principle. Gases push the bullet down the barrel and the same gases pushes the case rearward, which cycles the gun. Except for few all SMG are simple blowback; MAC-10, Uzi, Asmi
• Delayed Blowback
Same as blowback but there is some additional mechanism that creates a mechanical disadvantage for the bolt causing it to open slowly; these can be roller/lever/cam/gas/radial delayed blowback. All of H&K's previous generation of guns are roller delayed blowback; MP-5, G3, HK-23E.
• Quasi-DI or DI-SS Hybrid
An ingenious way invented by Eugene Stoner to use half the DI system and the actual bolt as a short stroke piston. AR family of guns are the best known example.
• Short Recoil
Here the bolt and barrel are locked together during the initial phase of firing and they both "recoil" together for a distance less than the cartridge length; after this the barrel stops and the bolt continues. Almost all modern semi-auto pistols use this only; from the very first 1911 to the latest CZ P series pistol.
• Long Recoil
Same as Short Recoil but just like SS Gas Piston the barrel and bolt travel the whole distance of cycling. Kind of obsolete system; Auto-5 is perhaps the best example.
• Interia
Bit difficult to implement so currently only low powered shotguns use it. Here the interia of the Bolt Carrier Group itself is used to operate the gun. Can be very easily confused with a blowback system but it's a locked breech system as opposed to unlocked of blowback.
 
Entire AK203 is the scam pulled by OFB Babus and Russians. Now Russians went one step ahead and scammed the OFB Babus.


No wonder we are the country trying to give tenders for 5.56x45, 7.62x39, 7.62x51 mm guns to improve the infantry while screw logistics.

Great bc lad maaro saare Akal aaye thodi bkl mai
 

Its classic case when most of the time Russian equipment is disqualified they go to court like spoiled brat who isn't getting his way
they also went to court when india selected K30 biho Russian went to court thanks to them we have shitty shilka ciws
Same thing happened with aps when army wanted yahudi aps
