PLx Scope Mounts are 100% US-made from 7075 Aluminum and feature grade 12.9 steel hardware with a proprietary Electroless Nickel coating for unmatched durability in austere conditions. The innovative three-bolt design distributes recoil evenly with over 6 500 lbs of clamping force. Combined with dual machined recoil lugs and 3 cross bolt lugs PLx mounts can resist heavy impacts and sustained gunfire without ever shifting your zero—all while remaining lightweight and compact. Like all of the products this mount is backed by Primary Arms’ lifetime warranty.
