I did it another way with my M14.
First i edited the ubersound/ubersound.scr and added the line:
[code:c84f0]//m14
aliascache m14_snd_fire sound/weapons/fires_new/m14/m14_fire.wav Mult 100 0 0 soundparms 1.3 0.2 1 0.2 500 5000 weapon_npc loaded ducking maps "1 2 4 5 7 moh dm mp"
[/code:c84f0]

and i called the firing sound m14_fire and put it in sound/weapons/fires_new/m14/

Then i modified the hag and replaced m1carbine_snd_fire with m14_snd_fire.

and now it works fine.
