About the Cobra KING OS
The KING OS (Oversize) is Cobra's 2016 revival of its 1990s oversize concept: a full-hollow, oversized head whose CNC-milled face carries what Cobra called its largest "Sweet Zone" ever. Zone Weighting pushes mass low and around the perimeter, a tungsten toe weight centres impact on the enlarged face, and the grooves are progressive — V-shaped in the 4-6 irons, U-shaped in 7-PW and wedge-spaced on the GW and SW. Lofts are moderate for the class, with a 30-degree 7-iron and 45-degree pitching wedge. The stock set is eight clubs, 4-PW plus gap wedge, in steel or graphite; it reached retail on 25 November 2016 at $999 in steel. Lengths and swing weights below are the steel build, and offsets are converted from Cobra's published millimetre figures.

Finding a used set
The Cobra KING OS ran from 2016 to 2017 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.
