Primary Arms SLx Scope Mounts are made from 6061 Aluminum and feature steel hardware with an innovative three-bolt design that distributes recoil evenly with over 6 500 lbs of clamping force. Combined with dual machined recoil lugs and 3 cross bolt lugs SLx mounts can resist heavy impacts and sustained gunfire without ever shifting your zero—all while remaining lightweight and compact. Be sure to pair it with the SLx 30mm Top Cap Reflex Mount for adding an offset red dot sight to your setup. This mount is backed by Primary Arms’ lifetime warranty.
