Compact, doesn't stick out too far.
Overview
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.

FAQ
Should I mount this in front of my scope or behind it?
It’s entirely your preference. That being said, we prefer it in front of an LPVO, so the distance from your eye is greater, thus opening up your field of view. Plus, with some scope mounts, it tucks nicely away in front of the scope. Mounting it behind the scope could also get in the way of some throw levers. Try it both ways and see what you like best.
Should I run it with the riser plate or without?
This is preference as well. You can choose to run it at the same height as your scope if you want a consistent cheek-weld on the stock. However, as shooters we love a more “heads up” posture when shooting, so we prefer to use it with the riser plate, regardless of how the scope is mounted.
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.
