Dont be to hard on me lol.. I'm a total noob to the gta modding scene and this is my first gun.
Modeled it by myself , used part of a picture found somewhere on google ^^

How to :
Use the imgtool from gtagarage to open gta.img located in XX\Rockstar Games\GTA San Andreas\models
Replace both AK47.dff and AK47.txd with the ones that are in the .zip file , look up the ak and youre ready to go! =D
