Fn Scar 17S reliability hinges on quick, practical troubleshooting. This guide provides fast solutions to get your Fn Scar 17S running again, with a focus on safety and performance. Whether you’re dealing with feeding issues, misfires, or a stubborn jam, these practical tips keep you in action.
Key Points
- Perform a safe, partial field inspection before disassembly or more involved steps
- Verify magazines and ammunition compatibility with the Fn Scar 17S to prevent feeding issues
- Check for carbon buildup and lubricate the action and bolt regularly
- Inspect the gas system and ensure proper gas port function for reliable cycling
- When in doubt, consult the owner's manual or a qualified armorer for guidance
Common Quick Fixes for the Fn Scar 17S
First, ensure the firearm is unloaded and pointed in a safe direction. If the Fn Scar 17S fails to cycle, start with the magazine feed and ammo compatibility as simple, often-overlooked culprits. A quick magazine swap can reveal if the issue is magazine-related rather than a systemic malfunction.
Feeding or chamber issues. Check the feed ramp for debris, wipe it clean, and apply a light amount of lubricant to the bolt face and operating group. If rounds consistently fail to chamber, inspect the magazine follower and springs for wear.
Failure to fire or misfires. Inspect the firing pin and strike surface for obstruction or damage, and verify the safety selector is in the correct position. A clean, lightly lubricated firing group improves reliability, but avoid over-lubing.
Unreliable ejection or jams. Confirm the extractor tension is correct and there’s no stuck brass in the chamber. A brief tap-assisted rack can clear minor jams, but avoid forcing parts beyond their normal range.
Maintenance Tips to Prevent Future Hiccups
Regular cleaning and lubrication help Fn Scar 17S stay reliable. Use quality oil and avoid over-lubing, especially in dusty environments. Clean the bore from muzzle to chamber, inspect the gas system periodically, and replace worn components through proper channels.
Store and transport equipment securely, and inspect magazines for wear. Use ammunition within manufacturer specifications to minimize feed-related issues and ensure safe operation of the Fn Scar 17S.
What is the first thing I should check on Fn Scar 17S if it won't cycle?
+
Begin with the magazine and feed mechanism to rule out feeding issues. Then inspect the gas system and bolt carrier group for cleanliness. Always ensure the weapon is unloaded before inspecting.
Can I fix Fn Scar 17S jams at home, or should I seek a gunsmith?

Simple, non-destructive maintenance like clearing debris and re-lubricating can often help. If the problem persists, or if you’re unsure about the cause, consult a qualified armorer or gunsmith to avoid safety risks.
Should I lubricate the Fn Scar 17S after shooting or during routine maintenance?
+
Lubrication is part of routine maintenance and should be performed after cleaning and drying the firearm. Use manufacturer-recommended lubricants and apply sparingly to high-friction points.
What ammo should I use with Fn Scar 17S to avoid feeding issues?
+
Follow the ammunition specifications in the owner’s manual. Use proven, quality ammunition that matches the recommended chamber pressure and bullet type for reliable function of the Fn Scar 17S.
