Gas Cylinder Wrench
The gas cylinder wrench can also be used to conveniently hold the small end of the piston during cleaning. The large hole in the wrench has an internal D-shape that holds the piston from rotating without causing any damage. Both the ¼” and 3/8” steel and the ½” aluminum models are CNC machined and designed to fit all original USGI and most commercial gas cylinders.
*Special Note* - Springfield Armory rifles manufactured after 2014 have oversized gas cyclinders and will required part number 140112.
