Perfect fit - Atrius Development Forced Reset Selector

Paired this safety selector with my stock SOLGW LFT (liberty fighting trigger) that came in the Sons M4-L89 and it was an absolute match made in heaven. No hang ups and no binding. Removing the safety selector part of the system was a bit tough, I unscrewed the screw and I had to get a small punch and use the vise to remove the thumb selector part but other than that it went on as smooth as butter. Make sure you have hammer down and on safe with the safety hook thing towards the barrel when putting your upper on your lower. The rest will flow smoothly.
