Remington 700 trigger issues primarily involve risks of unintentional discharge, particularly in pre-2006 "Walker" triggers and 2006–2014 X-Mark Pro (XMP) models. Defects include firing when switching off the safety or without pulling the trigger, often caused by poor sear engagement, dirt, or excessive factory sealant.
Key Remington 700 Trigger Problems
- Unintentional Discharge: The most significant issue is the rifle firing without the trigger being pulled, often when the safety is moved to the "off" position.
- X-Mark Pro (XMP) Recall: Models produced between May 1, 2006, and April 9, 2014, were recalled due to excessive sealant (bonding agent) in the mechanism, which can cause failure.
- Walker Trigger Issues: Older models often face issues with the trigger connector becoming misaligned or contaminated, leading to accidental discharges.
- Trigger Failure/Tacky Action: Due to tight tolerances, the trigger can become contaminated with dirt or, in cold weather, oil can become thick (tacky), causing the trigger to fail to release the sear (failure to fire).
- Safety Failure: Some reports indicate that releasing the safety lever can trigger a misfire, a symptom often linked to poor maintenance or excessive modification.

Common Causes
- Contamination: Rust, debris, or dried oil/grease inside the housing.
- Excessive Adjustment: Too little sear engagement or a trigger weight set too low.
- Manufacturing Defects: Excessive sealant (on XMP triggers) or poor tolerance management.
- Replacement Issues: Some aftermarket triggers, if not adjusted correctly, can also lead to cocking or firing issues.

Remedies and Solutions
- Check Recall Status: Verify the serial number on the Remington recall website.
- Clean the Mechanism: Use aerosol gun cleaner/lighter fluid to flush the trigger assembly, followed by dry lubricant.
- Adjust/Replace: If comfortable, adjust the sear engagement, or replace the trigger with a high-quality aftermarket option like Timney, Shilen, or Huber.
- Professional Gunsmith: Have a qualified gunsmith inspect and clean the trigger to avoid potential firing issues.
