I came across this forum and started reading some of the posts and they all sounded very intelligent and helpful.
I have owned a couple different Sigs: 1911 scorpion, SP2022, mosquito and my latest Sig purchase is a 516 Patrol in FDE. Now, right out of the box I had an issue- it was dirty, like a thin black residue all over the BCG parts and the piston rod. I bought the 516 because I learned that they run cleaner and longer without having to clean. So, I asked the private dealer that I bought it from what his take on it was and he said "they test fire them." From what I have learned about the 516 is that it would take about 5000 rounds to get it as dirty as mine was. Trying to be optimistic, I just figured it could have been some sort of lube/oil that I am not familiar with that is darker in color. So I took a Rem Oil wipe to the BCG and wiped it all off. I then took it out and shot about 100 rounds through it, took it apart and it did get pretty dirty from just that, lots of carbon build-up. I understand the gas should not even reach the BCG so im not sure why it is that dirty.
Next is a simple question: I have a drop-in .22 conversion bolt. Can I use it with the gas piston system and if so, what setting should I have the piston on? I have heard mixed reviews on this topic.
So, if anyone has any information on why the rifle was dirty and/or information on the .22 conversion that would be great. Thank you.
