HI,
I'M LOGAN.

I'm a retired Canadian Biathlete. Five years ago I bought a 3D printer, made a standing block, and raced it on the World Cup that season. Two years years later, myself and two friends raced at the Olympics, with rifle stocks I built by hand. Let me tell you more about it.

FROM A STANDING BLOCK,
TO A WHOLE STOCK.

After our initial success with 3D printing smaller parts, I set myself a larger target — race with a stock I'd designed and built from scratch. It took three attempts (at least) but I got there. Every stock I'd used before was one-size-fits-all, which means the range of adjustment is always compromised for either taller or shorter athletes.

My early prototypes used a 3D-printed core wrapped in carbon fiber, all done meticulously by hand. Each one took 2+ weeks from start to finish. They combined the features I'd liked best from stocks I'd seen on the World Cup with the things I'd preferred on my own rifle. Those design choices all carried straight into the Mk.6.

With the help of my Dad and our friend Brett, we built a CNC machine to handle the specific requirements of cutting biathlon stocks. It runs a 4th rotary axis, which gives us full design freedom — no compromises forced by traditional 3 axis CNC production constraints.

The goal was a stock with as much customization room as possible. The core is CNC-cut Maple, deliberately minimal, so every rifle-athlete interface can be 3D-printed and swapped: pistol grip, standing block, prone hand-stop, cheek-piece, butt-plate. Two core sizes — Mk.6 and Mk.6s, the latter shortened and lowered for smaller athletes.

Fully equipped the rifle comes in at ±3.55 kg, and we use variable infill in the 3D-printed sections to balance it to each athlete's preference. Grips print in engineering-grade PBT-GF, textured or smooth. Clips sit on neodymium magnets hidden under a printed shroud. The butt-plate is tapered to a 7 mm offset from the barrel centerline — in my experience that gives the most consistent cheek and butt-plate contact.

THREE PRIORITIES

01
FIT
CNC-cut Maple core for stiffness. 3D-printed PBT-GF interfaces for fit. The Mk.6 and Mk.6S share the same architecture. The S is shortened and lowered for smaller athletes — not a watered-down build.
02
Durability
Strength where required, sacrificial parts where required. Our butt-hooks are designed to be breakaway, and in a worst case scenario, the butt-plate bracket is also designed to bend away to protect the integrity of the maple core. All our stocks ship with spare hooks and a spare bracket.
03
Service
All Mk6 and Mk6s come with lifetime service done locally at our shop in Cochrane, Alberta.

THE MK.6.
BUILT IN COCHRANE.

The goal was a stock with as much customization room as possible. CNC-cut Maple core, deliberately minimal, so every rifle-athlete interface — pistol grip, standing block, hand-stop, cheek-piece, butt-plate — is 3D-printed in PBT-GF and tuned per athlete. Fully equipped, ±3.55 kg.
