Learn how to diagnose and fix common issues with your Blaser fixed mount for Zeiss scopes, including loose screws, misalignment, and poor fit. Practical steps for a secure setup.
Quick Answer
Most issues with a Blaser fixed mount for Zeiss scopes stem from loose mounting screws, improper torque, or debris under the base. Check and tighten the screws in the correct sequence, then verify alignment before final torque.
Why Fixed Mounts Loosen Over Time
Even a well-installed Blaser fixed mount can loosen after repeated recoil or temperature changes. The INNOMOUNT FM for Blaser and Sauer is built for stability, but the interface between the base and the rifle's receiver relies on consistent torque. If you notice the scope shifting or point-of-impact changes, check the screws first before assuming a defect.
Misalignment After Installation
A fixed mount that appears crooked or doesn't align with the bore is often caused by debris or burrs on the receiver or base. Clean both surfaces with a solvent and inspect for any raised metal. If the mount still sits unevenly, the base may need lapping—but this is rare with precision mounts like the INNOMOUNT FM.
Diagnosis Steps
- Symptom: Scope shifts after firing: Likely cause: Mounting screws are not torqued to spec. Action: Remove the mount, clean threads, apply a drop of medium threadlocker, and retorque to the manufacturer's recommended value (typically 15-20 in-lb). If screws hold after 10 rounds, the issue is resolved.
- Symptom: Mount does not sit flush on receiver: Likely cause: Debris or burr on the receiver or base. Action: Clean both surfaces with isopropyl alcohol and inspect with a magnifier. If a burr is present, carefully remove it with a fine stone. If the mount still rocks, stop and check the base for warping.
- Symptom: Scope reticle is canted (tilted) after mounting: Likely cause: Uneven torque on the ring screws or misaligned base. Action: Loosen all ring screws, align the scope with a bubble level, then tighten in a crisscross pattern to equal torque. If canting persists, the base may need lapping or replacement.
