The Project X Rifle Flighted shafts were discontinued by Royal Precision and these are what we have remaining. The 5.0 flex which is no longer available was the 3B2M. Depending on your set make up you could make the 5.5 flex play closer to the 5.0 by what we call soft stepping the shafts. This means installing the 3 iron shaft into the 4 iron and cutting the 4 iron to the 4 iron length. This will make the shaft play closer to the 5.0 flex and the 3B2M code. The 5.5 (3.5B2M) play not quite a half a flex stiffer then the 5.0 (3B2M) would play.
