The MDT Stalker Core LOP Spacer lets shooters extend the length of pull on their Stalker Core Buttstock, adapting its ultra-low stock length to a more traditional fit as needed. It's designed to slot easily into MDT's modular Stalker Core system, giving shooters flexibility to adjust their setup for different body types, clothing layers, or shooting positions without buying a new buttstock. Installation follows MDT's typical tool-friendly approach, keeping adjustments quick and repeatable in the field or at the range. This spacer is a natural complement to the Stalker Core Buttstock and Cheek Riser, rounding out a fully adjustable, minimalist stock system. As with the cheek riser, this is a newer accessory in MDT's lineup, so I'd confirm exact spacer thickness, weight, and included hardware directly with MDT before finalizing the listing.
