Product Details
The Anti X is the centerpiece of Defiance Machine's competition action lineup. Machined from pre-hardened 416 stainless steel with a 4340 chrome moly bolt turned from a single billet — no welded or pinned components. The receiver features an integral skeletonized scope rail and integral recoil lug, eliminating separate components that can shift under recoil.
Built for F-Class, PRS, and long-range hunting, the Anti X is known for consistent ignition geometry, precisely controlled headspace (guaranteed ±.001"), and repeatable bolt lockup. Aluminum shroud and lightening cuts keep weight between 23 and 24.4 oz depending on configuration.
Accepts Remington 700 footprint triggers, barrels, and stocks. BDL or AICS/AW magazine feed. Right or left bolt. 0 or 20 MOA integral rail. As a Defiance Machine partner, MOA Rifles builds Anti X-based rifles as part of our standard lineup and can spec the action to your build before assembly.
