I have used frog lube for about a year. It is great to protect the finish while storing your firearms however it does get thick and has similar properties of syrup. I took a friend shooting and had the firing pin gum up and cause misfires from light primer strikes. I am switching back to oil.
I have been looking at all kind of complete uppers to complete a build. While I'm not sure what the final build will be, I came across Hardened arms. I did a search and found a few members own and an IP is selling their uppers. Can anyone give a review on them from experience?
