When weight matters, the Defiance Machine anTi delivers.

If you watch your scales as closely as you watch your targets, you will want to check out the Defiance anTi action—a minimalist take on Defiance’s legendary precision actions. Weighing under 21oz, it still carries the same guaranteed headspace as the Ruckus or Tenacity with integral lug. The Defiance anTi is made of pre-hardened 416T aircraft-grade stainless steel with a chrome moly bolt. Featherweight. No compromises.

Like everything Defiance Machine products, the new anTi is built with a "no compromises" mentality to ensure the end user's expectations are exceeded.
