Learn how to install a Blaser quick-release mount for ATN scopes, including alignment, torque, and zeroing tips for a secure fit.

Quick Answer

Install a Blaser quick-release mount by aligning the mount base with the rifle's rail, securing it with the provided screws, and then attaching your ATN scope using the correct size option. Always verify the mount is fully seated and torqued to spec to maintain zero.

Why a Dedicated Adapter Matters

A Blaser quick-release mount is designed to fit the specific rail system on Blaser and Sauer rifles. Using an adapter like the INNOMOUNT zero ensures that your ATN scope sits at the correct height and alignment, which is critical for maintaining a consistent cheek weld and eye relief.

The INNOMOUNT zero is engineered for ATN4 and ATN5 optics, including popular models like the Thor 4, Thor LT, X-Sight 4K Pro, X-Sight LTV, and X-Sight 4K INT. This compatibility means you can swap scopes quickly without re-zeroing every time.

Choosing the Right Size Option

The INNOMOUNT zero adapter comes in different size options to match your scope's tube diameter and your rifle's rail configuration. Before you start, confirm which size you need by checking your scope's specifications and the rail type on your Blaser or Sauer rifle.

If you are unsure, measure the tube diameter of your ATN scope (typically 30mm or 34mm) and compare it with the adapter's size options. Using the wrong size can lead to poor alignment and a loose fit.

Installation Steps

Prepare the Rifle: Ensure the rifle is unloaded and the rail is clean and free of debris. Wipe the rail with a cloth and check for any burrs or damage. A clean rail is essential for a secure fit.
Attach the Adapter Base: Place the INNOMOUNT zero adapter base onto the rifle's rail, aligning the recoil lug with the corresponding slot. Tighten the screws gradually in a crisscross pattern to the manufacturer's recommended torque. Use a torque wrench to avoid over-tightening.
Mount the Scope Rings: Attach the scope rings to the adapter base, ensuring they are evenly spaced. Place your ATN scope into the rings, aligning the tube with the center of the rings. Check that the scope is level before tightening.
Secure the Scope: Tighten the ring screws evenly, alternating between left and right, to the recommended torque. Avoid over-tightening, which can damage the scope tube. Use a torque wrench and follow the manufacturer's specs.
Test the Quick-Release Function: Engage and disengage the quick-release lever several times to ensure it locks securely and releases smoothly. Confirm the mount is fully seated each time. If the lever does not lock firmly, re-check the alignment.
Zero and Confirm: Take the rifle to the range and zero the scope. After zeroing, remove and reattach the mount to verify that the point of impact remains consistent. A good quick-release mount should return to zero consistently.
