ATN TICO 6 Scope Mounting System 40mm Objective 46.7mm Clamp

ATN's TICO 6 hangs off the front of a day scope, and it needs a clamp cut for that scope's objective housing. This is the 46.7mm version, which covers most riflescopes built around a 40mm objective lens. The thermal mounts to the front of the ring, so the day optic keeps doing the aiming while the TICO handles the picture.

Objective lens size and housing outside diameter are different measurements. A 40mm scope can wear a housing anywhere from the mid forties to the low fifties in millimeters depending on the maker and the wall thickness. Put a caliper on the bell and check the number before you order, because a clamp that is close is a clamp that will not hold zero.
