Blaser-Sauer ATN4 vs ATN5 Quick-Release Mount: Which to Pick

The mount is the same; the rail option is the real choice

The INNOMOUNT QD adapter for Blaser and Sauer rifles is listed as compatible with both ATN4 and ATN5 optics. That means the ATN4 vs ATN5 decision does not change the mount model itself. What changes is the rail configuration you select: a 10 mm Picatinny rail, a 15 mm Picatinny rail, or no Picatinny rail.

So the practical question is not which mount fits ATN4 versus ATN5, but which rail option matches the rest of your setup. The supplied product information confirms ATN4 and ATN5 compatibility and names the supported ATN models, but it does not list rail dimensions for each optic or rifle. Use the rail choice as your main selection step, and verify the interface on your specific ATN device before ordering.

What the catalog confirms about ATN compatibility

• Montage amovible Blaser - Sauer - ATN4 | ATN5: The INNOMOUNT QD adapter is described as compatible with ATN4 and ATN5 optics. This is the core compatibility claim: the mount is not split into separate ATN4 and ATN5 versions.

  

• Montage amovible Blaser - Sauer - ATN4 | ATN5: The listed supported models include Thor 4, Thor LT, X-Sight 4K Pro, X-Sight LTV, and X-Sight 4K INT. These are the specific ATN devices named in the supplied catalog text, so they are the safest starting point for a fit check.

Rail options: 10 mm, 15 mm, or none

The mount is offered in three sizes. The catalog does not explain which ATN model uses which rail, so treat this as a decision you confirm against your own optic and rifle interface.

• With 10 mm Picatinny rail: Choose this only if your ATN optic or accessory interface is confirmed to use a 10 mm Picatinny rail. The supplied information does not state which ATN models require this size.
• With 15 mm Picatinny rail: Choose this only if your setup is confirmed to use a 15 mm Picatinny rail. As with the 10 mm option, the catalog does not map this size to specific ATN models.
• Without Picatinny rail: This option is for setups that do not need a Picatinny interface. The catalog does not describe which rifles or optics this version suits, so confirm your mounting interface before selecting it.

Blaser and Sauer fit: what is and is not stated

The product title and description name Blaser and Sauer rifles, and the mount is presented as a quick-release system for those rifles. That is the extent of the rifle-fit evidence in the supplied record. It does not list individual Blaser or Sauer models, receiver dimensions, or installation steps.

If you are choosing between this mount and a fixed mount for a Blaser or Sauer rifle, the quick-release design is the main difference. The catalog describes a fast and secure attachment, but it does not provide repeatability data or zero-retention claims. For a night vision setup where you remove and refit the optic, ask the seller to confirm the rifle model and mount interface before purchase.

Price and variant evidence

• Montage amovible Blaser - Sauer - ATN4 | ATN5: Catalog price is USD 269.56, with a comparison price of USD 369.26. The price applies to the mount family; the rail variant you choose is the same product record.
• Montage amovible Blaser - Sauer - ATN4 | ATN5: Available sizes are Avec rail Picatinny 10mm, Avec rail Picatinny 15mm, and Sans Rail Picatinny. These are the only variant options supplied, so your decision should start with the rail interface rather than the ATN4 or ATN5 label.

How to decide between ATN4 and ATN5 for this mount

Because the mount is listed for both ATN4 and ATN5, the optic generation alone does not decide the purchase. Start with the rail interface on your ATN device, then confirm the rifle fit with the seller. If your ATN model is one of the named supported models, the remaining question is the rail size.

Do not assume that a 10 mm or 15 mm rail option will fit every ATN4 or ATN5 device. The supplied catalog does not provide that mapping, and the absence of detail is a limitation of the evidence, not a statement that any rail will work. When in doubt, ask for the rail specification of your exact optic before ordering.
