This will edit Sniper "pbx4 super" and RPG "AT3-X" (the best sniper rifle and the best rpg). https://youtu.be/3LHm-8f0Ygs <- video here

Sniper:

full auto. No recoil. No scatter. High impulse on vehicles. Higher bullet speed. Lowest (almost 0) damage on vehicles, objects and people if not headshot. One-shot if headshot. Infinite ammo. No reload. Secondary shot as default.

RPG:

full auto. No recoil. No scatter. Infinite ammo. No reload. High impulse. No cooldown. Highest damage.
Primary shot mode: Higher bullet speed. 1 rocket per shot. Instant.
Secondary mode: I made it funny so no instant rockets  (you have already in primary mode instant rockets). No recoil and instant burst shot when pressing secondary shot button. All 4 rockets are shot from higher the player (took me hours to do this).

both weapons have a fire rate of 0.1 this means that even if they're fast but you'll always be able to shot only 1 shot with 1 click. If you lower this value, you'll often show twice with 1 click.
