being honest Viv Krishnan is indeed right about one point, you shall see it in this post,
notice the buttstock part...you see there are actually two buttstock adapters here ?

first adapter of course is on rear receiver side of the rifle itself with that round button, and other adapter is there from FAB kit...so this jugaadu arrangement not only uses two adapters for affixing a length adjustable buttstock but also, trichy's adapter folds on right side of the weapon while FAB one folds on left side...so both adapters are actually opposite side folding ones here!
^THIS is why standardisation matters...you can always jugaad out things for upgrades but then such things happen when their aim is only like 'just get it done' instead of 'get it done properly'...
I still have high hopes with Trichy and wish it from bottom of my heart that they just don't blindly kopy paste it but use their own fucking brains to make a true equivalent to what we are getting from russians instead of just experimenting out like this
