LIMITED EDITION SPECIAL RUN
 
               Armorer's quality gas cylinder wrench. Steel 3/8 thick, manganase phosphate coated. The gas cylinder wrench is a must have tool to safely hold the gas cylinder to remove the piston for periodic cleaning. Without the wrench, you can easily over-torque the gas cylinder and damage the internal splines and the slots in the barrel.  To remove the piston, use the wrench to hold the gas cylinder and with a 3/8 6-pt box wrench remove the gas cylinder plug.  Re-torque to 15 ft-lbs.
Dual-purpose wrench - The wrench also has a D-shaped hole to convenently hold the small end of the piston, from rotating, during cleaning. 
CNC machined and designed to fit all original USGI M14 and most commercial M1A gas cylinders.
Special Note: Some later model Springfield Armory rifles have investment cast gas cylinder that are larger diameters than the orginal forged USGI M14 gas cylinder.  If you have an investment cast gas cylinder you will need our oversized Alum wrench p/n: 140112.
