MK1C has metal butt profile, It was MK1A who had polymer one though in practice it is also changed to metal one.
Assam rifles MK1A share same buttstock as regular 1B1 folded one, I think in practice MK1C will also share same buttstock as 1B1`s have ..
What you suggested can be true, But my suspicion is due to its hand-guard design which looks like a rectangle..
=======
Usually its one LMG, one grenadier and marksman given as per need, 1B1 and SVD are used by Marksmen ..
One cannot shoot a human size target at +500m with iron sights at field conditions ..
How many machine guns are available in each squad?
Sharpshooter with which caliber? And can any one shoot at 600m with iron sights?
I haven't seen .50 cal with IA in any pics?
Kunal, that is regular insas, foldable butt version. The metal pipe construction of the butt is quite visible. The Mk1c has a flat polymer butt profile.
