Primary Arms SLx Cantilever Mount Features The Primary Arms SLx Cantilever Mount uses an innovative three bolt design that distributes recoil evenly across the mount body producing over 6 500 pounds of clamping force to keep a 30mm scope tube locked in place shot after shot. Dual machined recoil lugs combine with three cross bolt lugs to resist heavy impacts and sustained gunfire without ever shifting a shooter s zero. That level of mechanical redundancy is exactly what professional and competitive shooters look for when mounting glass they cannot afford to lose alignment on mid match or mid mission. The mount is built 100 percent in the United States from 7075 aluminum the same grade of aluminum used throughout the firearms industry for strength critical components. Grade 12.9 steel hardware secures the mount finished with a proprietary electroless nickel coating that resists corrosion in austere field conditions better than standard zinc plated hardware. At a 1.5 inch optical centerline and a 4 inch length the cantilever design positions a 30mm scope at a comfortable height and forward reach for a wide range of shooting positions. The black hardcoat anodized finish adds further durability while keeping the mount s 5.9 ounce weight low enough not to burden the rifle.
