Here is great video info on the L-39;

QUESTION: HOW OFTEN SHOULD THE BUFFERS BE REPLACED?

Answer: The L-39 users manual does not describe buffer change and sadly I have never seen an armory/armorer service manual giving guidelines.

Based on use and rounds fired one could RKI-guess that;

- The cartridge case buffer (rubber) should be changed after first signs of wear and deformation (parts of rubber missing etc.) so that one does not end up with badly dented ejected brass cases or having an uncontrolled "bounce path" of the case if hitting bare metal upon ejection.

- The bolt buffer (rubber) should be changed if showing deformation upon inspection after 200 normal cartridges fired, or if bolt carrier seems to hit (metal on metal) increasingly hard during maximum rearward cycle.

----

Look at how controlled the cartridge case ejection is when case buffer rubber is doing its job (reduce video replay speed to just 0.25 to really see details of buffer function);
