The T.REX offset mount is a minimalistic approach to mounting an offset optic on your rifle. Offsets provide a fast 1x aiming solution that is readily available by rotating the rifle in your shoulder. The offset optic also functions as a reliable backup optic platform. Each mount includes a riser plate, allowing users to run it higher than the standard height depending on your needs or primary optic setup.

For example, some scopes are very picky about eye-relief and in those cases, running a Standard ~1.50″ scope mount makes more sense as it allows the shooter to get a tight cheek-weld to the stock in the same place every time. Even still, we’d prefer to run the Offset with the riser so it’s easier to shoot on the move with. Again… this comes down to preference.
