Learn the step-by-step process to install a fixed Blaser mount for Zeiss scopes, including alignment tips and common mistakes to avoid.

Quick Answer

To install a fixed Blaser mount for Zeiss scopes, first ensure the rifle is unloaded, then attach the INNOMOUNT QD base to the Blaser or Sauer receiver, align the Zeiss scope rings, and torque all screws to specification.

Why Choose a Fixed Mount for Zeiss Scopes

A fixed mount like the INNOMOUNT QD for Blaser and Sauer rifles provides a stable, repeatable platform for Zeiss scopes. Unlike detachable mounts, fixed mounts offer a lower profile and fewer moving parts, reducing the risk of zero shift over time. This makes them ideal for hunters and shooters who prefer a permanent scope setup.

Tools and Preparation

Before starting, gather a torque wrench (inch-pounds), a hex key set, and a non-marring mallet. Clean the receiver and mount surfaces with isopropyl alcohol to remove oil or debris. Always verify the rifle is unloaded and safe before beginning any installation.

Step-by-Step Installation Process

1. Prepare the Rifle and Mount: Ensure the rifle is unloaded and the action is open. Clean the receiver mounting area with a solvent. Place the INNOMOUNT QD base on the receiver, aligning the recoil lug with the slot. Hand-tighten the base screws to hold it in place. Check that the base sits flush without rocking; if it does, re-clean the surfaces.
2. Attach the Scope Rings to the Scope: Loosely attach the lower halves of the Zeiss scope rings to the scope tube. Do not tighten fully yet. Ensure the rings are centered over the scope's ocular and objective bells for proper eye relief. Common mistake: Overtightening rings before aligning the scope can cause tube damage or misalignment.
3. Mount the Scope Assembly to the Base: Place the scope with rings onto the INNOMOUNT QD base. Align the ring bases with the mounting slots. Tighten the ring-to-base screws evenly in a cross pattern to the manufacturer's torque spec (typically 15-20 in-lb). Use a torque wrench; guessing torque can strip threads or cause the mount to loosen under recoil.
4. Set Eye Relief and Level the Reticle: With the rifle in a stable rest, slide the scope forward or backward to achieve a full, clear sight picture. Rotate the scope to level the reticle with the rifle's vertical axis. Tighten the ring screws to the specified torque (usually 18-22 in-lb). Check eye relief from your natural shooting position; a scope too far forward can cause a black ring at high magnification.
5. Final Torque and Verification: Re-check all screws with the torque wrench. Apply a small drop of blue Loctite to the base screws if not pre-applied. Cycle the bolt to ensure clearance. Take the rifle to the range for a bore-sight confirmation before live firing. After the first 20 rounds, re-torque all screws; heat and vibration can cause slight loosening.
