Springer Precision

140mm Magazine Extension for CZ 75 Mecgar 17 Rd


Springer Precision EZ CZ 140mm basepads for the CZ75 Mecgar 17 round magazines. Our extended capacity basepads are CNC machined from aluminum and hard anodized for a long service life. This lengthens the magazine and adds rounds to your magazine.  The unique locking mechanism allows a very solid attachment with a simple backing out of the discrete set screw. They fit the USPSA 140mm magazine gauge. 


Custom engraved and custom colors are non-returnable.

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

**Disclaimer: As with all competition geared changes, always make sure you test and check your gear before you take it to a competition setting.  With 140mm/170mm magazine configurations especially, check the magazine in a USPSA 140mm/170mm gauge to make sure it fits.  With mass produced items like magazines, sometimes they can vary slightly from one to the next, often in the magazine lips that connect with the magazine extension/basepad.
