"Rh_m14ebr_LongSD" ---- M14 Long Barrel Short Dot
"Rh_m14ebrLong" --- M14 Long Barrel Iron Sight
"Rh_M14Ebr" --- M14 Standard Iron Sight
"Rh_m14ebr_SilSD" --- M14 Silenced Short Dot
"Rh_m14ebr_SilGrip" --- M14 Silenced Iron Sight Grip
"Rh_m14mag" --- Standard M14 mag
"Rh_m14sdmag" --- Silenced/Subsonic Mag
