Weapon base/mod

[bloodmasked]

Looking for a weapon mod/base to use in a server which has better or more 'realistic' features and capabilities

such as:
- damage drop off at range
- increased spread and recoil for every consecutive shot, with a cap/limit of the inaccuracy
- recovery times for spread and recoil
- movement speed changed while equipped
- reload timing and equip time
- stagger enemies (think csgo mechanic)

-features typical from m9k, penetration, movement accuracy, etc

thanks for responses
