MDT LSS Gen3 Chassis System Black - Remington 700 Long Action

The MDT LSS Gen3 Chassis System transforms the Remington 700 long action into a precision tactical platform with enhanced ergonomics and modularity. This aluminum chassis system provides a rigid foundation that improves accuracy potential while offering extensive customization options for competitive shooting and tactical applications.

What Makes This Different

The LSS Gen3 features a fully machined aluminum construction that eliminates the flex inherent in traditional polymer stocks. The integrated V-block bedding system creates consistent barrel-to-chassis contact, while the modular design accepts standard AR-15 pistol grips and buttstocks. This chassis weighs approximately 3.2 pounds, adding structural integrity without excessive bulk compared to heavier tactical chassis systems.

Key Features

• CNC-machined 6061-T6 aluminum construction for maximum rigidity
• Integrated 20 MOA Picatinny rail for optics mounting
• AICS-pattern magazine compatibility (magazines sold separately)
• Standard AR-15 buffer tube interface for buttstock options
• Multiple QD sling attachment points and M-LOK slots
• Adjustable length of pull from 12.5" to 15.5"
• Type III hard anodized finish for corrosion resistance

Field testing demonstrates consistent sub-MOA performance when paired with quality barrels and ammunition. The chassis maintains zero through temperature changes and heavy use, making it suitable for precision rifle competitions, tactical training, and hunting applications. The quick-detach barrel system allows for easy maintenance and caliber changes when combined with compatible barrel systems.
