I have one very similar to that called the “Bristle Brush cactus” here’s pic:

Could very well be that but then again I’m not much of an expert

yes! good eye.  
the scientific name of this plant is right, the mammillaria spinosissima f. rubrispina. this specific variety though, characterized by the red spines, the common name is the red-headed irishman.
