140mm Magazine Extension for FN 509 9/40

$39.50

Springer Precision 140mm extended capacity basepads for FN 509 9/40 are CNC machined from aluminum and hard anodized for a long service life. This lengthens the magazine and adds 3-4 rounds to your magazine. The unique locking mechanism allows a very solid attachment with a simple backing out of the discrete set screw. They are specifically designed to work with our mag wells and fit the USPSA 140mm magazine gauge. 

*We include a .050 hex driver that makes installation and removal a breeze.
