ALG DEFENSE - ERGONOMIC MODULAR RAILS - PRODUCT INSTALLATION VIDEO

Ever been on website and wonder why ALG/Geisele has a purple wrench? What is it for? In this video Bill Geisele explains what is, what the ridges on it are for, and how it is used. I bought one because it was on clearance, haven't used it yet, because I haven't bought a hand guard that uses that style nut. This is a longer video, but it goes through in detail how to do it right the first time. I don't use a Geissele Action rod, I use the Brownells version which cost about half as much.
