Lets face it, you probably have an AR-15, maybe a couple of them. And if you don’t already have one, you’ve probably thought about getting or building one. If you aren’t aware, there are a few specialized tools you need to build an AR-15 or take one completely apart. The main things you may run into are the barrel nut, castle nut and free float rail components, but you may also need something for compensators or flash suppressors. I’ve used many tools to grapple with these, ranging from specialized tools, to off-the-shelf Craftsmen wrenches. Many off-the-shelf tools are OK for things like the compensator/flash suppressor and the other various pins and screws. But for dealing with things like a castle nut and free float rail installations, you really need specialized tools, and one that will hold up to some use . . .
