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 FASTER
STAY STEADIER
The flat, wide Competition Forend with a intergrated 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, accessories. Make it yours.
