Quick answer

Use the INNOMOUNT ZERO mount, designed specifically for Blaser and Sauer rifles, to securely attach your Infiray Hybrid thermal. This guide walks through the five key steps for a stable, repeatable installation.

Why a dedicated mount matters

Blaser and Sauer rifles have a unique rail geometry that differs from standard Picatinny or Weaver systems. Using a universal mount often leads to poor alignment, inconsistent zero retention, or even damage to the thermal unit. The INNOMOUNT ZERO is machined to match the Blaser/Sauer interface exactly, ensuring the thermal sits square and at the correct height.

What you need before starting

You will need the INNOMOUNT ZERO mount for Blaser/Sauer, your Infiray Hybrid HYH35W or HYH50W thermal, a torque wrench (inch-pounds), and a small flathead screwdriver. The mount comes with screws pre-installed, but check they are the correct length for your rifle model. Avoid using thread locker unless specified by the mount manufacturer, as it can complicate future removal.

Step-by-step installation guide

  1. 1. Prepare the rifle and mount: Ensure the rifle is unloaded and the action is open. Clean the mounting rail on the receiver with a dry cloth to remove oil or debris. Slide the INNOMOUNT ZERO onto the Blaser/Sauer rail from the rear until it clicks into place. Check that the mount sits flush against the receiver. Common mistake: Forcing the mount onto the rail from the front can damage the locking mechanism. Always slide from the rear.
  2. 2. Attach the Infiray thermal to the mount: Remove the protective caps from the mount's clamping surface. Align the Infiray Hybrid thermal's base with the mount's dovetail. Tighten the two clamping screws alternately in small increments using a torque wrench set to 15 in-lbs. Do not overtighten. Checkpoint: After tightening, the thermal should not wiggle. If it moves, the screws may be uneven or the base is not fully seated.
  3. 3. Verify eye relief and alignment: Shoulder the rifle in a natural shooting position. Adjust the mount's fore-aft position by loosening the rail clamp screws slightly and sliding the entire assembly. Re-tighten to 15 in-lbs once you have a full field of view and comfortable eye relief. Common mistake: Setting the mount too far forward or back can cause a restricted field of view or cause the thermal to hit the scope bell on recoil.
  4. 4. Torque all screws to spec: Using a torque wrench, tighten the rail clamp screws to 25 in-lbs (or the value specified in the mount manual). Then re-check the thermal clamping screws at 15 in-lbs. Work in a crisscross pattern for even pressure. Checkpoint: Under-torqued screws can loosen under recoil; over-torqued screws can strip the threads or crack the thermal housing.
  5. 5. Perform a function check and zero: Cycle the bolt to ensure the thermal does not interfere with the action. Take the rifle to the range and fire three shots at 50 yards to confirm the point of aim matches point of impact. Adjust the thermal's reticle if needed, then re-tighten all screws after zeroing. Common mistake: Skipping the function check can cause the bolt to hit the thermal, damaging both the rifle and the optic.
