MDT LSS Gen3 Competitor Kit Rem 700 SA

MDT LSS Gen3 Competitor Kit is a competition-ready aluminum chassis for the Remington 700 short action and its clones. The components are selected for PRS, NRL and other precision rifle competitions: a wide Competition forend with an integrated ARCA rail, an SRS-X Lite buttstock and an Elite Vertical Grip.

The flat, wide Competition forend has a 254 mm (10") ARCA rail on the bottom, so the rifle locks directly onto a tripod or bipod clamp and sits steady on barricades. The sides and bottom have M-LOK slots and pockets, plus drilled and tapped holes for control and NV bridges.

The chassis is built on MDT's LSS Gen3 platform: the action beds into an aluminum V-block bedding, it takes short action AICS pattern magazines and has an ambidextrous magazine release. Any AR-15 style grip fits, and the chassis has an integrated barricade stop and is compatible with an M-LOK thumb shelf.

Length of pull on the SRS-X Lite buttstock is adjusted with spacers. As the system is fully modular, the grip, stock and forend can be swapped later, and weights, bridges and other accessories can be added.
