This complete set of headspace gauges provides a higher level of accuracy than a single go and no go gauge set. Perfect for competition shooters, or for those trying to get the highest level of accuracy as possible out of their rifles. Each gauge is clearly marked in .001" increments for very fine adjustments.
- Used to find exact headspace length by chambering each of the gauges working up in order of length.
- May be used for determining brass sizing or the reaming of a chamber.
