NOLFY Posted August 26, 2020 Report Share Posted August 26, 2020 Tech question. An mg34 using decent 8mm all of its life and generally has remained nicely functional. In the 40 years of ownership In the same family has always been properly cleaned. Always the same day immediately after each use. Always painstakingly hot soap and water and then oil...takes hours. The question. A small pit inside the main receiver. Well known and well focused on at all times. Understood how the receivers were soft metallurgy as to their history of twist. The question is once that very top surface is breeched even if ever so slightly, Is the metallurgy of such metal that it would deteriorate more quickly over time (like a Pennsylvania pot hole in the road). Regardless of how well it is cared for? Quote Link to comment Share on other sites More sharing options...
challenger70rt Posted August 26, 2020 Report Share Posted August 26, 2020 I don’t know the answer to your question, but I bet I know where your from. Do t worry, NOTHING deteriorates as fast as a Pennsylvania road! Quote Link to comment Share on other sites More sharing options...
johnsonlmg41 Posted August 27, 2020 Report Share Posted August 27, 2020 As you keep introducing more water into the gun, it will continue to "rust" as the oxygen travels in with the water. Don't use water, use appropriate solvents like hoppes 9 to clean it. Quote Link to comment Share on other sites More sharing options...
