I have been asking around a little about whats avail. and what works and what doesn't work with NK bars and chains for my 346, and it seems like were a little limited with whats avail. out there . Does the stihl MS260 use an NK bar and chain , what other saws come factory with it ?? Oregon seems very limited with only the 95VP and then you got woodland pro 22NK, a much better choice . I've have been told not to run a regular chain on a NK bar as the rails are thinner and it will wear out the NK bar quicker . Just seems like its odd stuff and not much avail. for it . Any more ideas???
