A scope can be placed on a Taurus Tracker, but the process is not as simple as it would be with most other firearms. The reason for this is that the Taurus Tracker uses a unique bullpup action, which places the barrel behind the trigger. This makes it difficult to align a scope with the bore of the gun.
There are a few ways to overcome this obstacle. One is to use special weaver-type scope mounts that attach to the rear sight assembly. These mounts allow you to place the scope forward of the action, making it easier to get a good sight picture. Another option is to install a rail system on top of the gun so that you can more easily mount your optic of choice.
No matter which route you go, keep in mind that getting a proper zero will be more difficult than usual with a Taurus Tracker. Make sure you take your time and do plenty of research before committing to any particular setup. With a little effort, though, you should be able to get your Taurus tracker shooting straighter than ever before!
