Built as part of the elite PLx line, this mount delivers uncompromising strength, precision machining, and rock-solid zero retention, making it the ideal foundation for serious optics.

Crafted entirely in the USA from ultra-strong 7075 aluminum and paired with hardened grade 12.9 steel hardware, this mount is designed to endure harsh environments and sustained recoil without failure.
