How to confirm the fit
- Read your bar. The pitch and gauge are stamped on the guide bar near the saw body — e.g.
3/8" LP .050". - Count drive links. Lay the old chain flat and count the teeth that ride inside the bar groove. This number must match exactly; length in inches is not enough.
- Match all three. Pitch, gauge and drive-link count all have to agree with a row in the table above. Two of three is not a fit.

FAQ
What size chain does a Stihl MS 271 take?
The Stihl MS 271 runs a .325" pitch, .050" / .058" / .063" gauge chain. Available bar lengths: 13", 14", 15", 16", 18", 20". Match the drive-link count to your bar (see the table above).
How do I know which gauge my MS 271 chain is?
Check the number stamped on your guide bar near the tail, or measure the drive-link thickness with calipers. Common gauges for the MS 271 are .050" / .058" / .063", .050", .050" / .063".
Can I put a longer bar on my Stihl MS 271?
Oregon lists 13", 14", 15", 16", 18", 20" bars for the MS 271. Stay within this range — a longer bar than the engine is rated for cuts slowly and accelerates wear.
