Description

A3 Industries Modular Collapsible Telescoping Stock 8.5in Black. With an ultra-compact footprint and minimalist construction the MTS adds only 2.00'' of length to the firearm when collapsed (with the shortest buttplate). The system offers four length positions via a push-button mechanism and can be fired fully collapsed on most firearm platforms. The stock body can be mounted in two vertical positions providing a 1'' offset to accommodate various sight heights or ejection-port clearances. A proprietary Picatinny mounting interface replaces the traditional side clamp with a compact rail insert and two #8 set screws resulting in a stronger sleeker and more user-friendly design. All aluminum components are machined from 6061 and weight-optimized while the 3/8'' 4140 steel rods are Melonite-coated for durability and corrosion resistance. The MTS system supports four optional buttplates- A3T Magpul #1 Magpul #2 and Xtendo narrow-to fine-tune length and shoulder feel.
