Hey, so the model on the RVN sights is pretty bad atm. Its very "low poly" feeling if you look at the sight ring in the centre, all of the edges are very jagged and it doesn't even create a proper circle actually because of this, if you look at the top left and top right of the inner circle you can see what I mean. I think the red dot in the centre is also just a tad too chunky? It could maybe be replaced by the red dot that is used for the baraka sights or the m68 optic imo.
