When I installed my JRA barreled action into my new Sage Model 0 stock I installed the so called Crush Washer with the tapered side facing as per the instructions. The Gas Lock timed exactly even with the Gas Cylinder bore on lockup. The Rifle cycles 100%. While at the range recently I happened to notice that the Washer can be rotated with very little effort indicating no pressure is being exerted onto the Washer. So is this an actual Crush Washer or just a Spacer to compensate for the lack of a front band ?
