More about the rifle
MKEK JNG-90 or Bora-12 is a Turkish national sniper rifle with 7.62mm diameter, 1000m point target and 1200m effective target. TSK JÖH actively uses JNG-90 in operational regions. The first designer of the weapon was Necmi Güngör, a 1990 graduate gendarmerie non-commissioned officer.
I looked at some photos of the gun, and I realized that the end of the scope doesn’t have the glass bulging out like that.
This is more nit-picky, but the color of the modeled gun is lighter than the real life reference picture.
The part at the end of the stock is a little bit larger and more prominent than your model.
I don’t know what they call them, but the little handle that you pull on the gun is a lot smaller and thinner on your model compared to the real life picture.
The end of the barrel has a little raised piece. It doesn’t look like you have that on your model.
Maybe you should start texturing this gun, so it looks as realistic as possible?
