First move is to deep clean the action.
Check the ejector for free movement and good spring tension.
The ejector should have a good amount of tension.
Remove the ejector assembly from the left side of the receiver by removing the two outer screws on the outside.
Pay attention to how the ejector and spring fit into the ejector "box".
Disassemble the bolt by lifting the firing pin out and carefully prying the extractor out.
Inspect the ejector, spring, and ejector box for wear or deformed parts.
Inspect the bolt for damage around the front, and inspect the extractor for wear, bends, or other damage.
A common fault is an extractor that's bent or has lost tension, or has a damaged hook.
Lubricate everything and reassemble.
Make sure the upper cartridge guide is in the inside "roof" of the receiver and make sure it curves downward not upward.
Remove and inspect the cartridge guide in the right receiver wall, clean it and the recess in the receiver wall and lubricate.
AT THE RANGE, load a round in the chamber and slowly operate the lever to pull the cartridge out of the chamber and watch as it attempts to eject it.
Try slowly ejecting a fired round and watch to see what's causing the problem.
Most times the problem is a worn, bent, or altered part, or a fouled receiver.
