MDT LSS Gen3 Chassis

MDT is expanding of its LSS Gen3 Chassis System with options for three more actions: the Tikka T3x in a left-handed short action, the Tikka 1X right hand, and the right-handed Howa 1500 Mini Action. These additions bring more options to the modular LSS GEN3 platform, giving shooters even more ways to build their perfect rifle setup.

The LSS Gen3 is MDT's most adaptable chassis system to date and is designed around a central core chassis that mates to the rifle action. This allows end users to customize their handguard and buttstock without compromising their zero and create a rifle tailored to their needs for either competition, hunting, tactical operations or general shooting.

These new configurations join existing models for Remington 700 short action, Savage short action, Tikka short action, Tikka T3x in a right-handed long-action and the CZ 457, expanding the system's reach across popular rifle platforms.

MDT LSS Gen3 Features:

  • Core center chassis with multiple buttstock adapter options, including XTN, carbine, pistol brace, and fixed
  • Handguards and buttstocks can be hot swapped without affecting rifle zero
  • Accepts standard AR-style grips.
  • Ships with MDT's Ambi Mag Latch; compatible with the MDT Adjustable Mag Latch.
  • Available in Black and Flat Dark Earth (FDE).
  • Choose from Competition, Hunting, and Tactical fore-ends to suit your mission.

The LSS Gen3 system is offered in a modular format. Customers select their desired inlet, choose a buttstock adapter and then pick from a lineup of mission-specific handguards to create a rifle chassis unique to their needs. With the addition of these new inlets, MDT continues to set the standard in modular rifle chassis design, ensuring more shooters can experience the precision, adaptability, and performance that define the LSS Gen3.
