Mr Mower Parts Chainsaw Bar 24" Forestry-Pro Professional Quality Solid Steel bar with a Replaceable Sprocket Nose Fits Stihl

What It Is

This is a 24-inch solid steel chainsaw bar with a replaceable sprocket nose, designed for professional or heavy-duty cutting. It’s intended for use with Stihl chainsaws, but is an aftermarket replacement part—not OEM.

Fitment & Compatibility

Before buying, verify these three things:

• Bar mount pattern: This bar is designed for Stihl saws with a specific mount pattern (typically “large” mount, e.g., MS 660, MS 880, or 090). Check your saw’s bar mount type—Stihl uses different patterns for small, medium, and large saws. Your saw’s model number is on the housing.
• Gauge and pitch: Confirm your chain’s gauge (e.g., .050″, .058″, .063″) and pitch (e.g., 3/8″, .404″). This bar will only work with chains that match those specs. Measure your current chain or bar groove width.
• Drive link count: A 24″ bar typically requires 84–92 drive links depending on gauge and pitch. Count the links on your current chain—if you buy the wrong count, the chain won’t fit.

⚠️ OEM vs aftermarket: This is not a Stihl-branded bar. Aftermarket bars may have slight differences in oil holes, bar thickness, or tail shape. Always compare physically to your original bar before installing.

Key Things to Know

• Quality concerns: The single 1.0-star review suggests possible fit or durability issues. Solid steel bars are heavy and durable, but poor manufacturing can lead to oiling problems or premature wear.
• Sprocket nose replacement: The replaceable sprocket nose extends bar life, but sourcing a compatible replacement nose may be difficult for an off-brand bar. Check availability before buying.
• Installation difficulty: Easy if fitment is correct—remove bar nuts, swap bars, reattach chain and tension. But if the mount pattern is wrong, you’ll need to return it.
• Common gotcha: The bar may not align perfectly with Stihl’s oiler port, causing poor chain lubrication. Test oil flow before heavy use by running the saw briefly and checking for oil on the bar.

Should You Buy It

Only if you have a large-mount Stihl saw and are comfortable verifying fitment yourself—and you can accept the risk of an unrated aftermarket bar. For the same price, a known-brand bar (e.g., Oregon) with solid reviews is a safer bet. Skip this if you need guaranteed fit or professional reliability.
