Depends on what's broken. Do you just need to get a new Windage Turret? Or is there an issue with the windage adjustment not working?
Unfortunately if it needs any major repairs it will likely cost more than what you paid for the scope. The newer made Tasco scopes don't have a great reputation for the older Japan production tacos scopes. Trace Scope repair is an option but I believe they only work on Japan made Tasco scopes.
Nothing is physically broken (at least outside) but the windage adjustment is not working...you can hear and feel clicking (less crisper than elevation turret) but there is absolutely no horizontal crosshairs movement.
Likely just from wear over time. I would think it needs a rebuild. Reach out to Trace and see if he can assist. Which model is this scope and do you know the country of manufacture?
Cheap Chinese copy. I think the labour cost will be more than a value of the scope...I'll toss it.
Sounds about right for Tasco as soon as they come out of the box.
