Features

  • Robust Three-Bolt Design – Distributes recoil forces evenly with over 6,500 lb of clamping force to maintain zero under sustained fire.
  • Dual Machined Recoil Lugs – Front and rear steel lugs bite into the Picatinny rail, preventing axial or rotational movement.
  • Premium Aluminum Construction – CNC-machined from 6061-T6 aluminum for strength and rigidity with minimal weight.
  • Hardened Steel Hardware – Cross-bolts and clamp blocks resist shear and deformation under heavy recoil.
  • 1.5″ Optical Centerline – Ideal height for consistent cheek weld on AR-style platforms.
  • Mil-Spec Torque Specifications – Ring caps torqued to 16–18 in-lb; base to 30–35 in-lb for secure mounting.
  • Lightweight – Weighs just 5.8 oz (164 g) to preserve rifle balance.
  • Lifetime Warranty – Backed by Primary Arms’ no-fault, transferable lifetime warranty.
