Since you have loosened the restrictions on sights in the previous major update, there are currently a lot of gun sights for each operator, which is a good personalized option.
However, I found that there were some problems with the way these sights were installed. The firearm itself has its own Picatinny rail, but for some reason, a guide rail is often installed in the guide rail of sights and firearms. My guess is that the sight restrictions were released and the corresponding sight installation screen was not made according to different firearms.
I hope you can optimize the way the sights are installed for each weapon in the game so that the sights can be properly mounted on the Picatinny rails of different firearms.
I look forward to hearing from you soon and thank you for understanding.
Above,best regards
Your, sincerely player
