AR-15 Extended Safety

thingiverse

A coworker recently approached me with a question about an aftermarket safety extension for his AR-15, specifically one that features a larger paddle designed for hunting in cold weather with thick gloves. He was unable to find this particular style of safety anymore, which prompted him to ask for my assistance. I began by searching online and discovered an STL file on GrabCAD (https://grabcad.com/library/safety-catch) that appeared to be a model of the stock safety on his AR-15. Using this as a reference point, I created a custom CAD design that incorporates an extended paddle onto the internal base of the safety. After testing the new safety, I'm pleased to report that it has performed flawlessly so far!
