100-500 USD
One can purchase rifle scope mounts from websites like Optics Planet, Cabelas, Amazon, Scope Mounts, Airgun Depot, eBay, Talley Manufacturing and Jmecks Scope Mounts.
Just about any rings and mounts made by Weaver will fit nicely. Using lesser quality rings will cause the scope to go out of adjustment when the shotgun is fired.
Its a 20mm weaver rail. So almost ALL scope mounts will fit on it
You will have to contact Weaver to find out.
It all depends on the Daisy Scope rings that you have. The M4 has a removable front and rear sight. This will allow you to add a scope to the Weaver rail mount on the M4 if your scope rings are the weaver size. If not, then you need to purchase weaver scope rings for your scope.
