About the Epon AF-505
The AF-505 is Epon's one-piece forged pocket-cavity players-distance iron that preceded the AF-506, built from an S20C billet with the thinnest face of any one-piece forging in the line at the time - about 2 millimetres, roughly the thickness of a nickel - to combine forged feel with distance and forgiveness while carrying over the AF-503's loft/lie chart essentially unchanged. Epon's own AF-506 launch material describes that model as "keeping the loft/lie chart of its predecessor," which is the AF-505 - confirmed here by an identical 22-50 degree loft ladder across both models. Ginone Golf's custom-order catalogue places the AF-505 in its 2018 product year, roughly a year earlier than some marketplace descriptions suggest; the AF-506 succeeded it when Epon announced that model on 19 February 2021. Heads are built to order with no fixed stock shaft; lengths below are the standard steel assembly lengths from the Japanese retail spec chart, and offsets are converted from Epon's published gooseneck figures in millimetres.

Frequently asked questions
What is the loft of an Epon AF-505 7-iron?
The Epon AF-505 7-iron has a loft of 31 degrees, a lie of 62 degrees, and a standard steel length of 36.75 inches.
What replaced the Epon AF-505?
The Epon AF-506, announced on 19 February 2021, replaced the AF-505 while explicitly carrying over its loft and lie chart.
How thin is the face on the Epon AF-505?
About 2 millimetres - roughly the thickness of a nickel - the thinnest face of any one-piece forged iron in Epon's line at the time, intended to blend forged feel with super-game-improvement-level ball speed.
Finding a used set
The Epon AF-505 ran from 2018 to 2021 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.
