The standard M-4 / AR-15 pistol grip pisses me off to no end. I suffered through my time in the service with that piece of crap, as did a lot of people. I still see them sold on stock rifles and with lower parts kits.
Recently I got my hands on a couple grips, and rather than sending them to the landfill, I figured there had to be a way to get something useful out of them. As it turns out, with a small in vestment of time and a few tools, you can make a decent grip out of them. In this video I explain how-to take a stock rifle pistol grip and hack it into something ergonomic for your next rifle build.
