Stihl MSA 120 C-B Chain Questions

What size chain does a Stihl MSA 120 C-B take?

1/4" pitch, 0.043" (1.1mm) gauge on the MSA 120 C-B. The standard 12" bar takes 64 drive links. Note: this 1/4" chain is not interchangeable with 3/8" LP chains used on the MSA 200/220.

How many drive links is an MSA 120 chain?

64 DL on the standard 12" bar. The DL count is usually stamped on the bar itself, or count the drive links on your old chain. You can also use our Search by Chainsaw tool.

Is this a genuine Stihl chain?

No — it's an Alpine Chain Co. chain manufactured to fit the MSA 120 C-B, replacing the Stihl 71 PM3 and Oregon 25AP. Same pitch, gauge and drive link options, with a semi-chisel profile chosen for Australian hardwood. Every fit is backed by our Guaranteed Fit system.

How to Verify Your Chain Size

If you are unsure if this is the correct chain for your Stihl MSA 120 C-B, check the side of your current guide bar. The Pitch, Gauge, and Drive Link (DL) count are typically stamped directly into the bar near the mounting bolts.
