BFSIII® Carbine Buffer Springs

The BFSIII® Carbine Buffer Spring is an increased power buffer spring that is useful for tuning a BFSIII® equipped firearm. Since gas system lengths, pressures, and other variables may change the way your firearm functions, we cannot guarantee that this spring will work in every application.  Franklin Armory recommends consulting with a professional gunsmith that is familiar with the AR platform for help with tuning your firearm.
