Saw a few threads on Rimfire Central and You-tube videos on this and decided to try it. Basically you just remove the trigger spring and flip it over. Doing so was said to noticeably lower the trigger pull. I did it by following along with a video, no gunsmithing ability needed. It was easy to do, and it indeed feels like it lessened the trigger pull. I've since put a couple of hundred rounds through my Buckmark with no ill effects. Nice, simple to do, free mod. Just Google Buckmark spring flip. Anyone else here tried this?
