Taran Tactical Innovations Base Pad for STI/SV Magazines Gen 4 Red 1

Taran Tactical Innovations Base Pad for STI/SV Magazines Gen 4 Red 1. Tightening the base pad screw is not recommended and may be difficult because the screw is set with Loctite; trying to force the set screw to turn could result in stripping the screw. We do not warranty base pads for stripped heads on set screws or pins lost in result of tampering with the set screw. The 4mm is our mid profile extension for the Staccato/Infinity/Springfield Prodigy/Atlas/Infinity 9/38 2011 style magazine. Alth
