Rimfire rifles may not draw the attention of centerfire pistols, but the world of rimfires has changed in recent years due to the 'customization' of both rifles and pistols. A perfect example of an accurized .22 rifle is the Smith & Wesson M&P-15 .22. After given the special custom treatment by gunsmiths in the S&W Performance Center, you'll simply be amazed at the performance of this AR-styled rimfire, whether you're punching paper or zeroing - in on a headshot on a squirrel barking from a treetop.
