The combination of this particularly narrow guide bar with the small-link 3/8" Picco Micro Mini 3 saw chain or the 1/4" Picco Micro 3 (designed especially for cordless chainsaws and the MS 150 / MS150 T) offers considerable savings in weight coupled with improved cutting performance. Like all STIHL guide bars, it is made of high-grade chrome molybdenum steel.
