Springer Precision STI/SVI 2011 140/170mm Base Pad

Springer Precision 140mm / 170mm basepads for STI/SVI 2011 are CNC machined from aluminum and hard anodized for a long service life. These basepads for 2011 magazines include special flaring that makes installation and removal much easier than many conventional basepads. Springer Precision also made a subtle relief cut "well" within the basepad that gives you a little more room for spring compression. The unique locking mechanism allows a very solid attachment with a simple backing out of the discrete set screw. They fit the USPSA magazine gauge for 140mm and 170mm mags. The unique attachment design provides a low profile, sleek design that is very stable and easy to remove. Grams Extra Capacity Follower Kit Please read the four options below carefully.
