Util.Effect AR2 particle?

Hello. I’m currently expanding the emitter tool, and someone asked me to put the AR2’s Muzzleflash. So using this list: http://maurits.tv/data/garrysmod/wiki/wiki.garrysmod.com/indexe14a.html I searched for it, but i couldn’t find it

anyone happen to know the ar2 Muzzleflash Particle name that i can use with the Util.Effect script?

Thanks in advance
