Whether you call it an AR-15, a modern sporting rifle or a black rifle, this style of rifle is America's runaway favorite! The modern sporting rifle is versatile, accurate and fun to shoot ... but its inner workings are more complex than Grandma's old bolt-action. In this video from Smith & Wesson's GUNSMARTS series, instructor Ken Scott shows you the basics of field-stripping your AR-15.

Field-stripping is really nothing more than disassembling, cleaning and reassembling your gun. Knowing how to do it will not only make it easy for you to keep your black rifle in terrific working order, it will also give you more confidence in your rifle and your ability to use it effectively. As Scott says, "there's a lot going on here," but with this video and your friend the owner's manual, we know you've got this.
