Hi MPGH, after seeing krew951's post about m16a3 > g36e, i had a go at it, completed all the graphical stuff, but at the end, he says
"for the sounds extract GUNS_SND_AR using RezXtract and replace the m16a3 folder with mine", i've got rezxtract, and i have extracted the .rez file and replaced the m16a3 with his one.
But what do i do next? when i'm in game the m16a3 sounds the same

Have i missed anything out? Please help !
