The Shepherd is the result of two brands pushing each other to the edge of performance. At its heart: a match-grade barrel mated to a Geissele MK8 handguard to create a rifle that points naturally, mounts optics cleanly, and lets you hold tight groups under pressure. Radian ambidextrous controls keep work easy and intuitive; the M16-milled lower gives a factory-solid feel that won’t loosen up after heavy use. The Annex Dead Wings two-stage trigger brings the kind of clean, confident break you expect from a precision build, while the A5 buffer system soaks up recoil and sharpens follow-up shots. Finished with Magpul furniture for proven ergonomics, the Shepherd is equally at home on the range, in competition, or on duty.
