Try giving the chamber a good cleaning to remove any fouling.

Inspect the ejector for wear or deformation.

Clean the bolt and bolt carrier, and receiver thoroughly and apply a good lubricant.

Check for any binding of the bolt and carrier in the receiver.

Clean and inspect the magazine for fouling or damage.....try a different magazine.

Install a new extractor, spring, and plunger.

Inspect/replace the recoil spring.  Lubricate it lightly.

Inspect/clean the gas port in the barrel.

Inspect/clean the gas tube and gas block.
