DEFIANCE MACHINE - AnTi ACTION

WHEN WEIGHT MATTERS
 
Weighing as little as 19.2 oz.
 
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 aircraft-grade 416 stainless steel receiver, paired with a chrome moly bolt. Featherweight. No compromises.
