All weapons so far are fine, but when I drop the M82 on the ground, the metal that attached the scope to the rail and the scope lenses are purple/black textures for me.

Please can someone tell me what source I need for those textures? I play DarkRP and it really irritates me. I have all the counter strikes, TF2, portal 2, Day of defeat, L4D2, HL deathmatch, and HL episode 2.

I'd love it if someone can help me, thanks guys!
