Learn how to securely mount a Blaser optic using a multirail Picatinny adapter. Step-by-step instructions for 11mm rails, with common mistakes to avoid.
Quick answer
Mount your Blaser optic using a multirail Picatinny adapter like the INNOMONT model, which fits 11mm Blaser rails and includes secure mounting screws. Follow the steps below for a stable, repeatable zero.
Why a multirail Picatinny adapter for Blaser?
Blaser rifles use a proprietary 11mm dovetail rail that is not directly compatible with standard Weaver or Picatinny rings. A multirail adapter bridges this gap, letting you mount a wide range of optics without modifying the rifle. The INNOMONT Multirail Picatinny is designed specifically for Blaser 11mm rails and comes with four M3.5 x 5.8 x 5 screws and a slot for secure installation.
Common mistakes to avoid
Over-tightening the mounting screws can strip the threads or damage the rail. Use a torque wrench if possible. Also, ensure the adapter is centered on the rail before tightening; an off-center mount will affect eye relief and zero. Finally, always check that the screws are fully seated in the rail slots—partial engagement can lead to the mount shifting under recoil.
Step-by-step installation
- Prepare the rifle and adapter: Unload the rifle and remove any existing scope or mount. Clean the 11mm rail on your Blaser with a solvent to remove oil or debris. Place the INNOMONT multirail Picatinny adapter on the rail so the slot aligns with the rail's recoil stop (if present). A clean, dry surface prevents the mount from slipping under recoil.
- Insert and tighten the mounting screws: Insert the four M3.5 x 5.8 x 5 screws through the adapter into the rail slots. Tighten them evenly in a cross pattern (front-left, rear-right, etc.) to avoid tilting. Use a hex key or torque wrench set to 2.5–3 Nm if available. Uneven tightening can cause the adapter to sit crooked, affecting scope alignment.
- Attach the scope rings and optic: Mount your Weaver or Picatinny scope rings onto the adapter's top rail. Place the optic in the rings and tighten the ring screws to the manufacturer's recommended torque. Check that the scope is level and that eye relief is comfortable before final tightening. Recheck ring screws after the first few shots—they can settle and loosen slightly.
