Not all Enforcers were supplied with a scope - they would all have the scope mounts 'as standard' but depending on the 'cash left in the budget' they could be purchased with or without the Pecar scope, with or without a bipod, etc, etc. As funds allowed the local Police Force would buy the scope, bipod etc.
Talking with a 'scope repair' expert who was contracted to many of the Police Forces this resulted in some 'odd' (non-Pecar) scopes being used
