Product Description

This custom-built 6mm ARC ELR / PRS rifle was assembled by Three Oaks Tactical with a focus on precision shooting, adjustability, stability, and long-range performance. At the heart of the rifle is an American Rifle Company Coup de Grâce barreled action, paired with a Lothar Walthur heavy taper 26″ barrel. Mounted in an Ultradyne UD Picatinny Chassis and a complete suite of adjustable Ultradyne components.

The rifle features an Ultradyne Apollo Max .264 / 6.5mm muzzle brake, custom oversize shrouded timing nut, adjustable grip, adjustable thumb rest, Gen 2 adjustable butt stock, chassis weights, and Gen 2 bag rider. The chassis is also equipped with an NV bridge and M-LOK spare-round holder, providing a highly configurable platform for precision applications.

A TriggerTech Diamond trigger provides a premium trigger system, while the Vortex Strike Eagle 5-25x56mm EBR-7C MRAD scope is mounted using an American Rifle Company MBRACE 20 MOA scope mount. Upon request; we can exchange the MRAD scope with a MOA scope.

The rifle includes two MDT 12-round 6mm ARC magazines, a bipod, and a custom Pelican protective case. Three Oaks Tactical performs the build and provides the rifle bore sighted and range ready.
