This spring is NOT a factory replacement spring. IF you want a direct factory replacement spring for the 10 and 15 round magazines, contact FN America directly. With that said, we have tested this spring in both the 10 and 15 round magazines that come with the FN 502 Tactical 22LR. The factory springs in the 10 and 15 round 502 magazines are different in length from each other, the 15 being longer. The spring offered here as a replacement is shorter than both but will function. So if you are in need of a replacement magazine spring and can't find one, this one will work.

5 of 5 FN 502 Tactical / MRD 22LR Replacement Magazine Sp July 20, 2026
Reviewer: Ed Manning from Arlington, TX United States  
Very fast service and response, order processing and shipment was better than expected.  Quality product, while my personal FN was working well with extremely minor feed and/or extraction issues compared to others I decided to proactively change them out for the Taylor Tactical products.  So far, I am impressed with the performance - others who were experiencing feed/ejection issues when dirty are no longer experiencing the issues.

5 of 5 Fn 502 mag replacement springs May 15, 2024
Reviewer: Marcus M from Houston, TX United States  
They were amazing a little shorter then the factory original one, but work better now. With the 2 round mag extension they would not spring back up to cycle another round with the factory spring. After being replaced with this one works no problem now. Went to the range and fed over 300+ round with no issues.
