Product Information

When it comes time to reshaft your irons, reach for the True Temper Project X Rifle Shaft. Patented Rifle design features a discrete constant taper for each Project X shaft. Longer taper rates result in more energy transfer to the ball and higher trajectory for increased distance and carry. True Temper Project X shafts use a more precise, Frequency Matched (FM) system, for measuring flex. The number on each shaft represents a frequency in cycles per minute to precisely define the shaft's flex.


  • Designed to allow clubmakers to fine tune spin and launch of the Rifle to exact DNA of a golfer’s swing
  • Rifle construction perfectly blends tip responsiveness and tip stability for tighter dispersion and control
  • Frequency-matched design ensures tighter specs and tolerances for consistent flex progress through set
  • Longer taper rate that achieve a more dynamic transfer of shaft energy into the ball
  • Country of Origin : United States of America
  • Brand : Project X
