When weight matters

If you watch your scales as closely as you watch your targets, 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. Pre-hardened 416T aircraft-grade stainless steel with a chrome moly bolt. Featherweight. No compromises.
