Can a worn Gas Cyl cause failure to feed?

[Bill Hollinger]

Agree with the others. I left the screw lose once and withing two clips it started having FTF issues. If the gas escapes (worn cylinder or lose screw) it will have problems.

The back side is supposed to be somewhat oblong. You are supposed to measure the end with the gas port. A .530 Pin Gauge should not enter the power storke area more than halfway. The less it enters the less wear it has

Have You also preformed a tilt test with Your Rifle with the op rod spring removed?Have You checked the cylinder lock screw for tightness or cracks?Just a few things more You can check before You buy a new gas cylinder,and Yes,these were all culprits with My Rifles as well.

Thanks for responding. I did the tilt test with the spring removed - it slid smoothly on its own weight. I checked the cyl lock and screw for cracks, debris and tightness - all good. Unfortunately I dont have a gauge to test with, I'm using an inside mic and digital calipers.
