The .204 Ruger isn’t just a fast cartridge; it is a precision-engineered speedster that redefined the limits of the sub-caliber bolt gun. Built as a high-velocity solution for the varmint hunter, it rivals the terminal performance of the .22-250 while offering a significantly more efficient footprint.

This system thrives on its signature 32gr and 40gr loads, pushing projectiles at blistering speeds to provide an exceptionally flat trajectory that minimizes the need for complex hold-overs. If you’re building a dedicated long-range predator rifle or a high-volume bench rest setup, the .204 Ruger offers the "see-your-own-impact" recoil levels and the surgical accuracy required to dominate the open plains and push the boundaries of small-bore ballistics.

Ballistic Barn AR-15 uppers are American Made and machined by manufacturers of mil-spec AR-15 components.  All barrels are individually checked for headspace using Manson go and no-go gauges.
