I always wanted the short MP5, cutscene M4 and the Sniper from VC in SA, so i converted them.
replace the files with the original ones in your GTA SA gta3.img (make a backup before)
knocked a star off because the PSG1 is done wrong. the VC beta psg1 has no suppressor BUT the barrel length isnt cut. the barrel length should be the same size as the original psg1
