Shaft Weight 6.2 Grains Per Inch


Static Spine = NON FUSION ROD ADJUSTABLE 325 Spine


70S-50R Alloy Insert = 20 Grains

Stock "Inferno IBO Illegal Shafts" replace the 110 grain machined and heat treated Proprietary Mammoth SR Stainless Steel Machined insert with a lighter Proprietary Mammoth 70S-50R Alloy Machined insert. This is the only difference between the stock "Inferno IBO Illegal FOC KING Shafts" and the stock "Hot FOC KING Shafts." This makes a super strong externally footed dangerous game capable shaft with unprecedented GPI per spine in a non-unidirectional carbon arrow shaft configuration.  It can be shot at a super-light total arrow weight with a 100 grain point. It can also be set-up in a light total arrow weight with a 200 grain point to be able to run the heavier broadheads that you might want to utilize with lighter total arrow weights.


While there are other speed shafts on the market, they typically achieve lightweight gpi per spine with wimpy unidirectional carbon fiber construction designs that offer unacceptable hoop strength on animal impact and we do not do this!!! None of our arrows use wimpy unidirectional carbon fiber construction designs and the "Inferno IBO Illegal FOC KING Shafts" are the only speed shafts we know of that can be used on deer through dangerous game.  


Stock "Inferno IBO Illegal Shafts" are banned by most target archery sanctioning bodies do to their sub five grains per bow draw pounds with some arrow point configurations, unprecedented feet per second arrow speeds and/or target damage by the new Proprietary Mammoth SR Stainless Steel Shaft Saver-Bone Breaker Shock Collar External Footings, TM. "Inferno IBO Illegal Shafts" come with all of the machined inserts and components loose in the package. "Inferno IBO Illegal FOC King Shafts" can be used for antelope through elephant hunting and with 75 grain - 600 grain broadheads.
