Q&A Section:
Q: Will this magazine extension fit the newer FN Five-seveN MRD/MK3 model?
A: No, this magazine extension is specifically designed for the FN Five-seveN USG/MK2 model. If you're looking for extensions compatible with the MRD/MK3, please check our dedicated page for those models.
Q: Is professional installation required for the magazine extension?
A: We recommend professional installation for the best experience and optimal performance.
Q: What should I be aware of when handling this aluminum extension?
A: Aluminum magazine extensions should never be dropped. Dropping them may cause damage to the extension and/or the polymer body of the magazine.
Q: Do I need a different spring when using this magazine extension?
A: No, a different spring is not needed. We have extensively tested this extension with factory springs in proper operating condition. If you experience any cycling issues, it is highly likely that either there is an installation error or that your magazine is past its serviceable life and may need replacement.
Q: Can I use this magazine extension with aftermarket magazines?
A: No, this product is designed to work with OEM FN 20 round magazines only. Using it with aftermarket magazines may result in improper fit or function.
Q: Can I take the magazine extension on and off?
A: No, this magazine extension is designed to be installed semi-permanently. While careful removal is possible, it should not be taken on and off repeatedly, as doing so can wear out or potentially break the polymer magazine body.
Important Notice: Aluminum Magazine Extensions should never be dropped. Discoloration on non-visible areas (when installed) from the anodizing processes may be present. Not tested with or approved for FN 10 round magazines. Magazine not included.
