“wrhinehart”What on earth is an “O ring tune?”


Instead of a parachute style piston seal an Oring is adapted to the piston either by adding an adapter with a groove for the O-ring or machining an O-ring groove into the piston.
Here’s an adapter from Vortek’s site-quite a few springer field target guys use them.
