I really like the concept and design of Ghatak assault rifle but i think they should implement these things to their design too.
First thing is,Left-sided fire selector.
-------------------------------------------
As you can see in Polish Tantal Rifles,they put a 3-position fire selector on the left side of firearm (as majority of shooters are Right-handed so they can easily operate such fire selector with their thumbs).Even Israeli Galil rifles have them (and both Tantal and Galil are improved Kalashnikov variants.)
Tantal Rifle from Poland
Galil Rifle from Israel
even
Serbian Zastava M-21 rifle has Left-sided Fire selector similar to Galil
Note:Fire selector in Galil and Zastava rifles moves with Right side Dust cover cum fire selector (You can see it in following video)
but in Polish Tantals Right side Dust cover-cum-fire selector is independent to Left side fire selector and both Fire selectors are operated seperately.In Tantals,Right side dust cover-cum-fire selector has two mods - Safe and Fire (Like any Semi-Automatic only Kalashnikov rifle) and Left Side Fire selector has three mods - Semi-automatic (in middle position,marked as 'P'),Full auto (in far left position,marked as 'C') and 3-round Burst fire (in far right position,marked as 'S').
Left sided Fire selector in Tantal rifle,here the gun is set to Full auto mod.

Second thing is,Modular Right side Fire selector
-------------------------------------------------------------
Current Fire selector-cum-Dust cover for Ghatak is typical AK-type fire selector.I think they should implement this kind of Fire selector on Right side.

and Finally,Top Mounted Detachable Rails for Optics.
-------------------------------------------------------------------
Rails for Polish Beryl Rifle
This kind of Rails have little elevation so the Shooter can use Iron sights along with Optical sights,if Needed.
I know Rail section for INSAS rifle can do it too,but i think it should be put on Ghatak rifle in this format.
Some more things that should be added with Ghatak is,Folding+Adjustable buttstock,Illuminated Sights (so one can fire the gun during night using Iron sights).
P.S.
