Rifle model and first time using substance painter

Jaston3D

Hey everyone it's been a while since I've posted anything, started my last year of highschool.
Lately I managed to finish this model and get a decent bake out of it so I could move onto texturing. This was my first go at substance painter and I am in no means finished quite yet but I just want to get some critique on my texturing or even the piece all together. So any critique would be greatly appreciated!

maybe more shots from different angle? Lack subtle wear and tear but overall looks good and would be nice to see more

I don't think it needs any wear. I think it gets over used sometimes. The scope is way too shiny though. Look up some real scopes and see what I'm talking about.
