The Rifle Project X Taper Iron Shaft in 6.0 flex is a tour-proven, stepless steel iron shaft trusted by elite players worldwide. Engineered by True Temper under the iconic Project X banner, it delivers a penetrating, low-trajectory ball flight with exceptional stability and control — ideal for stronger swingers who demand precision from their irons. This individual shaft is cut specifically for a 6-iron at 39 inches with a .355 taper tip, making it a perfect custom-build or replacement option for discerning clubmakers and serious golfers alike.
Unlike conventional stepped steel shafts, the Rifle Project X uses a smooth, stepless profile. Each iron shaft in the set is built with a discrete constant taper length — meaning the 6-iron shaft has its own unique taper rate different from the 5-iron or 7-iron. This precise engineering optimises how flex is distributed along the shaft and how energy is transferred at impact, resulting in consistent feel and performance across every club in the bag.
The Project X Rifle 6.0 is engineered for a low-to-mid launch angle combined with low spin — characteristics that produce a piercing, workable ball flight. The stiff tip section resists unwanted twisting through impact, keeping dispersion tight even on off-centre strikes. This makes it the preferred choice for stronger players who prioritise accuracy and shot-shaping ability over high-launch assistance.
