UPFOREST 20" Chainsaw Bar & Chain Combo for STIHL MS311 MS391 — 20in Low-Kickback Guide Bar, Chrome-Plated Chain

UPFOREST's 20" chainsaw bar and chain combo is a direct-fit replacement for STIHL MS311 and MS391 models, offering a lightweight guide bar and a hardened, chrome-plated saw chain engineered for improved durability and smoother cutting.

If your Stihl MS311 or MS391 needs a reliable 20-inch replacement, this UPFOREST combo pairs a low-kickback guide bar with a high-strength chain made from heat-treated German steel and Japanese chrome plating. The set is designed for hobbyists and professional users who want better wear resistance, consistent tensioning, and a sharper cutting profile without swapping to a larger machine.

Will this bar and chain fit my Stihl MS311 or MS391?

Yes — the combo is manufactured to match the common specifications of the MS311 and MS391 guide bar and chain interface. Before ordering, confirm your chainsaw’s bar length mount pattern, chain pitch, and gauge to ensure exact compatibility.

• Designed for 20" bar length commonly used on MS311 and MS391
• Check chain pitch and gauge against your saw’s requirements
• Contact UPFOREST with model or bar specs if unsure

How do the materials and construction improve performance?

The chain uses heat-treated German steel for core toughness and a punching/tempering process for stability, while Japanese chrome plating on the cutters improves wear resistance. Together these processes reduce stretch, keep cutters sharper longer, and help maintain consistent tension under load.

• Heat-treated rivets resist wear and reduce tension change
• Chrome-plated cutters offer extended edge life
• Precision grinding and cold-heading deliver consistent cutter geometry

What benefits does the 20" low-kickback guide bar provide?

The 20-inch guide bar balances cutting reach with manageable control, producing less kickback than longer or more aggressive bar profiles. Its lightweight construction reduces operator fatigue, making it well-suited for extended cutting tasks or users who prefer a nimble saw setup.

• Reduced kickback for safer handling
• Lightweight design for easier maneuvering and less fatigue
• Appropriate for both gasoline and compatible electric saws

How should I maintain the bar and chain for longest life?

Regular sharpening, proper lubrication, correct chain tension, and routine inspection of rivets and bar rails will preserve cutting performance. Replace the chain if rivet wear, bent drive links, or persistent tension issues appear; rotate or flip the bar rails occasionally to promote even wear.

• Keep bar groove and oil hole clean for consistent lubrication
• Sharpen cutters with correct file size to retain geometry
• Maintain proper chain tension and inspect rivets regularly

Who this is for: The UPFOREST 20" Chainsaw Bar & Chain Combo is aimed at homeowners, arborists, and occasional-to-regular users of Stihl MS311 and MS391 saws who want a dependable replacement with improved durability. It's a practical choice for users who need a balance of reach and control—suitable for limb work, firewood cutting, and general property maintenance—while offering professional-grade material treatments that extend service life compared to uncoated or untreated aftermarket chains.
