What You Can Do With It
Handguard Changes: Remove the barrel nut to replace or re-install two-piece or free-float style handguards designed for the 15-22 platform.
Barrel Maintenance: Pull the barrel for detailed crown/chamber cleaning or inspection and re-torque to spec.
Receiver Protection: Safely service the 15-22’s polymer upper with proper holding tools, reducing risk of cracking or deformation from improvised methods.
How to Use (High-Level Overview)
Unload & Verify Clear: Remove the magazine and visually/physically check the chamber.
Secure the Upper: Use a receiver vise block or dedicated M&P 15-22 upper support to prevent flex.
Engage the Wrench: Seat the barrel nut wrench fully on the nut’s flats/lugs for maximum contact.
Loosen/Remove: Apply steady pressure—avoid jerky force. Use a torque wrench for reassembly.
Reinstall to Spec: Clean threads, lightly lubricate if required, and torque to the manufacturer’s specification. Confirm gas system/handguard alignment before final tightening.
Tip: Mark the nut and receiver with a paint pen before disassembly to track movement and help verify final alignment during reassembly.
Best Practices & Pro Tips
Use the Right Support: A polymer upper benefits from clamshell or block support—never free-hand against the bench.
Heat Helps (Sometimes): For thread-lockered nuts, controlled, low heat can soften compound; avoid overheating polymer components.
Torque Wrench Friendly: Pair with a calibrated torque wrench to meet spec and avoid over-tightening.
Inspect Threads: Clean, debris-free threads ensure consistent clamp force and reduce galling.

FAQ
Q: Will this wrench work on standard AR-15 (.223/5.56) barrel nuts?
A: No. It’s designed specifically for the M&P 15-22 barrel nut geometry. Use an AR-15 armorer’s wrench for centerfire platforms.
Q: Do I need any other tools?
A: We recommend a receiver vise block, a bench vise, and a torque wrench for proper installation. Depending on your handguard, you may also need hex/torx drivers.
Q: What torque should I use on the M&P 15-22 barrel nut?
A: Always reference the manufacturer’s current specification for your exact model/revision. Using a torque wrench ensures repeatable results.
Q: Can I damage my polymer upper?
A: With the correct vise block/support and steady torque, risk is minimized. Avoid excessive force, poor engagement, or unsupported twisting.
