MBR - Machined Ball Retention

Big Sky Precision's Sky-Loc with Machined Ball Retention (MBR) was awarded a patent with twenty-nine claims in May of 2002.

Traditional methods of ball retention swage the edges of the ball hole. In essence, an operator would pound the metal at the sides of a drilled hole, sometimes by hand with a hammer. Big Sky's MBR process revolutionized production and quality by utilizing precision computerized machines and our own proprietary, custom tooling.
