The .17HMR is one of my favorite rimfire calibers. The hot 17 caliber rimfire cartridge is both supremely accurate, and light recoiling making it a good step up from .22LR in terms of both inherent accuracy and range. Bear Creek Arsenal is following up the success of their .22WMR AR-15 upper with the release of the new BC-15 17HMR Billet Upper Receiver to give rimfire enthusiasts access to yet another popular rimfire cartridge that they can plink, hunt, or target shoot with by simply slapping it on an AR-15 lower receiver.
