Compare the two INNOMOUNT QD mounts for ATN4 and ATN5 optics on Weaver/Picatinny rails. Learn which version fits your scope and shooting style.
Quick answer
Both INNOMOUNT QD mounts fit Weaver/Picatinny rails and work with ATN4 and ATN5 optics, including the Thor 4, Thor LT, X-Sight 4K Pro, X-Sight LTV, and X-Sight 4K INT. Choose the two-piece mount if you want the lowest price; choose the size-specific version if you prefer a tailored fit for your exact ATN model.
Same rail, same optics: what actually differs
The two mounts share the same core compatibility: a Weaver/Picatinny interface and support for the ATN4 and ATN5 families. The practical difference comes down to construction and how the mount is sized. The two-piece INNOMOUNT QD is a single configuration, while the other version is offered in specific sizes. Neither listing states a weight or material, so base your choice on mounting preference and price rather than unlisted specs.
Quick-detach convenience vs fixed simplicity
Both mounts use a QD (quick-detach) system, so you can remove and reattach your ATN optic without tools. That matters if you swap between thermal and day optics on the same rifle. The trade-off is that QD mechanisms add cost and require you to check zero after reinstallation. If you rarely remove the scope, a simpler fixed mount could save money, but neither of these two products is a fixed mount.
Price vs tailored sizing
The two-piece mount is the lower-cost option at USD 228.00 (compared to USD 325.71). The size-specific version costs USD 232.63 (compared to USD 369.26). The price gap is small, so don't let cost alone decide. If your ATN model has a known size requirement, the sized version may reduce guesswork. If you want one mount that covers multiple ATN4/ATN5 optics, the two-piece design is the more flexible choice.
Decision rules for choosing your ATN mount
- If you own multiple ATN4/ATN5 optics: Choose the two-piece INNOMOUNT QD (product 1732351). Its universal compatibility lets you swap scopes without buying a separate mount for each. Confirm your rail is Weaver or Picatinny before ordering.
- If you want the closest fit for one specific ATN scope: Choose the size-specific INNOMOUNT QD (product 1732354) and select the size that matches your ATN model. Check the product options for available sizes. Measure your scope's mounting area or check ATN's specs to pick the right size.
- If budget is the priority: The two-piece mount is about USD 4.63 cheaper at catalog price. Both include quick-detach, so you are not giving up QD convenience by saving. Factor in the cost of a sizing mistake if you are unsure which size fits.
- If you rarely remove your optic: A fixed mount would be simpler and potentially cheaper, but neither of these products is fixed. If quick-detach is not essential, look for a fixed ATN mount instead.
