Description
The MDT LSS Gen3 Tactical kit brings serious versatility to your Tikka T3/T3x short action rifle. This isn't a stripped-down base or a minimalist build. You're getting a complete, mission-ready chassis system that works right out of the box and adapts to whatever you throw at it.
The core of this setup is rigid and rock-solid. The extended tactical forend features M-LOK slots on all five faces, giving you unlimited mounting options for bipods, lights, slings, weights, or spare ammunition. The all-metal construction doesn't flex under pressure, so your barrel stays free-floating and your shot groups stay tight.
Adjustable Buttstock Built for Real-World Use
The included Skeleton Carbine Stock (SCS) is where the Tactical kit shines for ergonomics. Toolless adjustments let you dial in length of pull, cheek height, and buttpad position on the fly without hunting for an allen wrench. You can even completely remove the rubber buttpad and flip the cheekrest if you're sharing the rifle with a left-handed shooter. This level of adjustability is rare in factory configurations.
Modular Platform That Actually Works
This kit represents the best of both worlds. It arrives fully assembled and ready to shoot, but because it's built on the LSS Gen3 platform, you're not locked in. Swap the grip for something more ergonomic. Change the buttstock if your needs shift. Replace the forend with a hunting or competition variant. The chassis doesn't need re-bedding or gunsmithing because zero retention is built into the design. Drop in your barreled action, tighten the screws, and you're running.
What the Tactical Configuration Brings
The extended forend and SCS buttstock make this feel like an AR-platform rifle, but you get bolt-action precision. The ambidextrous mag latch works with standard AICS-pattern magazines. Everything is cerakote finished for durability in the field.

Frequently Asked Questions
Does the LSS Gen3 require any gunsmithing to install?
No gunsmithing needed. Drop your barreled action into the chassis, tighten the included screws, and you're done. Installation can be done at the range with basic tools. The free-floating barrel channel and bedding are already engineered into the chassis.
Can I swap out the buttstock and forend on this Tactical kit?
Absolutely. The LSS Gen3 platform is fully modular. You can swap the buttstock, forend, and grip independently without affecting your rifle's zero. MDT makes competition, hunting, and tactical forends that work with this chassis. Any AR-pattern carbine stock works with the carbine interface included on the Tactical kit.
What magazines does this chassis use?
The LSS Gen3 uses standard AICS-pattern external box magazines, which are widely available. If your Tikka originally came with a blind or hinged magazine, this chassis converts it to AICS compatibility. The ambidextrous mag release makes dropping mags fast and easy.
How adjustable is the SCS buttstock?
The Skeleton Carbine Stock offers toolless control over length of pull and buttpad position. The cheekrest and rubber buttpad heights are also independently adjustable. You can even flip the cheekrest if someone left-handed wants to use your rifle, and the rubber buttpad assembly completely removes if needed.
