One of the things i love in other games is being to customize your "loadout" in shooter games like for example Call of Duty.
For rifles, currently there is attachment options are amplifiers, protection, scopes.
* Amplifiers haven't been implemented yet.
* Protection is for the gas masks (if more options for gas masks could be made + updated visual for the current one (view while wearing it)), would be great.
* Scopes - if its possible please make the scope view different for the different type of scopes, and add more options

Would like to see a thermal scope too, for sniper rifles (did i mention sniper rifle would be awesome?? (high damage (more than current high), high range (idk 185m?), slow firing (like 1 shot 3 sec?))
* If there was option of "night/day" or, places on the map where it is caves/tunnels/ valley, in other words "dark" places, then could add the items "nightvision goggles", and attachment for rifle - flashlight.
* make attachment "silencer" (to change sound, at cost of some range)
add grenades (or some type of explosive weapons)(or tactical weapons) (besides bombs with UG), make attachment "grenade launcher"
* For scopes, have changes lenses - for lense, be able to customize the color or lense (clear or see very light see though color) and also crosshair options and colors)
* Be able to paint your gun different colors or "patterns" "styles", for even more customization.
For most people they will not use these options, when skilling. Some might be used for hunting. but for pvp they would be used.
For melee weapons, I'm not sure what kind of customizations are possible.
