Old World Craftsmanship Meets Modern Tactical Billet Performance Up for auction from Shepard Arms is a true heirloom-quality masterpiece. We have synthesized the absolute pinnacle of modern billet engineering from San Tan Precision with the exquisite, traditional aesthetics of genuine walnut furniture from Woox. This is not a "parts bin" assembly; it is a meticulously sourced, purpose-built rifle designed to turn heads at the range while delivering sub-MOA reliability in the field.
The Shepard Arms Advanced Gas System Tuning We don't just bolt components together. We spent the time in the shop tuning this system to perfection. Utilizing a Superlative Arms Adjustable Gas Block and a specific spring/buffer combination, we have optimized the dwell time of this 16" Faxon barrel. The result is a rifle that cycles with incredible smoothness, minimal recoil impulse, and reliability that "out-of-the-box" factory rifles simply cannot match. This unit is tuned for reliability using Frontier Hornady 55GR ammunition.
