13″ ARCA SWISS RAIL

The Fierce 13″ ARCA Swiss Rail gives your MTN Reaper or Reaper HTAC a full-length attachment point for tripod shooting, bipods, and bag riders. Instead of a single fixed mounting spot, the 13-inch rail runs the length of the forend, letting you slide the rifle fore and aft in a tripod head or ARCA clamp to find perfect balance — no tools, no remounting, no hunting for the sweet spot with a loaded pack on your back.

ARCA Swiss has become the standard interface for serious field shooting, and for good reason: one rail connects your rifle to tripod heads, ARCA-compatible bipods, and shooting bags without swapping adapters. Machined from aluminum at 13″ x 1.5″, the rail adds a rigid, repeatable clamping surface while keeping weight where a mountain rifle can afford it.

Steep-angle shots across a canyon, long waits over a tripod in a glassing spot, or a quick prone setup off a bag — the full-length rail turns your Fierce rifle into a stable shooting platform anywhere in the field.
