Anyone own a .177 rifle or BB/ pellet bore bristle/ cleaning brush?

Suddenly occurred to me they might make great brushes to clean the harness connector cavities for the ECU, the VR, and the distributor pickup connector

.17 Cal. Rifle Bore Brush

Yeah, almost 100% sure I have one in a kit. I have a Ruger .177 break action pellet rifle. 1250FPS. It'll put a pellet through a dog's skull.
