Please note: you need to download GTA V Weapon Data which made by fkngoob due to ancient data corrupt my gameplay
Also after replace weapon.dat, you need to replace default.ide to avoid game crash due to game cannot understand what animation supposed to that weapon.

Copy and paste this lines in weapon.dat made by fkngoob:
$ M4 INSTANT_HIT 900 900 356 -1 5 rifle 30 35 0.74 -0.04 0.13 0 0 0.45 1.3 7 9 7 7 9 7 99 7001

I recommend use God Mode mods for CLEO from gtagarage, use for kill aggressive drivers from cheat with infinite ammo for more fun.
