Defiance Machine (Classic, Tenacity, Ruckus, anTi, and anTi X) Fixed Shoulder – 1.061″x16Px.950″

Defiance Actions Prefit Gun Barrel: Classic, Tenacity, Ruckus, anTi, anTi X 

Defiance Machine offers several actions with .001″ tolerance on their headspace datum. The Classic, Tenacity, Ruckus, anTi, and anTi X all have an offering with a .966″-.9665″ headspace length, which is what this fixed-shouldered builder is for. Our barrels are made with the counterbore for the bolt head, just like an R700 barrel, with enough clearance for the M16 or other extractors to function properly. *CRF or flat nose bolts will not work with our barrels at this time
