About the Bridgestone J36 Cavity Back
The J36 Cavity Back was the better-player cavity iron of Bridgestone's J36 forged line, aimed at "professionals to mid handicap amateurs." The head is premium-forged from 1020 mild carbon steel with progressive muscle thickness through the set for enhanced feel, a progressive-offset cavity design, a tapered sole for shot-making versatility and trailing-edge relief for a variety of lies. Lofts are traditional for the era (35-degree 7-iron, 47-degree pitching wedge), built to a D3 swing weight on a stock Rifle Project X flighted steel shaft with a Golf Pride Tour Velvet grip. It was sold right hand only as a 3-iron through pitching wedge. The Condition of Competition rule made the J36 irons non-conforming for professional play from 1 January 2010 (grooves), the same year the J38 generation succeeded it.

Finding a used set
The Bridgestone J36 Cavity Back ran from 2008 to 2010 and is no longer in production, so the used market is the only source. Search eBay, 2nd Swing, Golf Avenue and the PGA Tour Superstore trade-in listings, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.

- Note: the loft/lie/length/swing-weight/offset ladder published on Bridgestone's archived J36 Cavity Back page is numerically identical to the J36 Blade Irons page archived the same year — both are recorded here as published rather than assumed to be a data-entry duplicate, since the two models otherwise carry distinct construction copy (cavity vs. muscle-back) and distinct product photography
- year_introduced 2008 and year_discontinued 2010 follow Bridgestone's own archive path (clubs/archive/2008-models/) and the J38 generation's 2010 archive filing, which fixes this model's successor
