MDT The Competitor - LSS Gen3 Kit - Left Handed

The MDT The Competitor - LSS Gen3 Kit - Left Handed is a rifle stock and chassis component from MDT (Modular Driven Technologies), makers of precision rifle chassis systems, stocks and accessories. Available by action (Remington 700 SA, Tikka T3/T3x SA); colour (Black, FDE).

Optimized For Competition

If you're building a match rifle and want to skip the guesswork, this is it. The MDT LSS GEN3 Competition Kit takes the most modular rifle chassis system on the market and dials it in for one thing: winning stages.

No picking parts. No mismatched accessories. Just a rock-solid, competition-ready rifle foundation—straight out of the box.

Purpose-Built To Compete

Every piece in this kit is selected for one thing: to give you a leg up in PRS, NRL, and precision competitions. It’s not just modular. It’s optimized.

Shoot Fast, Stay Steady

The flat, wide Competition Forend with an integrated ARCA rail makes running barricades feel automatic. Lock in a tripod, clamp your bipod, and go.

No Flex, No Guesswork

This may be a pre-built kit, but it’s certainly not a compromise. You get the same rock-solid fitment and zero-retention the GEN3 is known for—with competition-ready parts already installed.

Upgrade-Friendly

Already a beast, but still fully modular. Swap the grip. Switch the stock. Add weights, bridges, and accessories. Make it yours.
