Shooters usually replace magazine release together with magwell. Other than that, installation of this part is easy and you can do it at home with a few basic tools.
Thing to bear in mind is compatibility: these mag releases are designed to fit CZ Scorpion Evo models, not Evo 3+.
PS: You can find all CZ Scorpion Evo magazine releases here.
