You get what you pay for! - Sako Optilock Ring Mount

I wouldn't use any other brand name ring in place of the Optilock rings, regardless of price. These rings fit the Sako integral mount precisely and they look as good as they preform.
Pros: Perfect fit, strong and solid ring with outstanding clamping force.
Cons: Hard to get.
