About the TaylorMade rac MB
The rac MB was TaylorMade's muscleback blade of the rac era, shipping from February 2003 as the workability-focused top of the range above the rac LT and rac OS. It is coin-forged from low-carbon steel with precision-milled rac Feel Pockets in the back to tune impact feel, a narrow sole with a blunt leading edge, and a compact head with a high, forward centre of gravity for a controllable, low flight. The stock set runs 1-iron through pitching wedge on Tour Flighted Precision Rifle steel shafts, with a 36-degree 7-iron and 48-degree pitching wedge. Specs below are the standard steel-shaft build; published swingweights are D2 (D3 pitching wedge) in the 6.0-7.0 Rifle flexes.
Stock shafts
- Precision Tour Flighted Rifle — steel · flexes: 5.0, 5.5, 6.0, 6.5, 7.0

Finding a used set
The TaylorMade rac MB ran from 2003 to 2006 and is no longer in production, so the used market is the only source. Search the used listings on eBay, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.
