This is not the most appropriate forum for this, but I've always received better gunsmithing advice here than anywhere else. I have an AK with an aftermarket trigger that while smooth, isn't what my precision guns have. Following the "fuck it, it's an AK" mentality, I thought I might throw the hammer and trigger in the vice and polish the hook and travel area with a brass wire brush in a dremel tool, and maybe even the steel wire brush to see if that smooths things out any. Any thoughts? Think it will work or destroy the trigger?
