The Bergara BMR Micro .22 WMR (brand part no. BMR004) is a compact bolt-action rimfire rifle built by Bergara for shooters who want centerfire-grade fit and finish in a small-game and pest-control platform. Its 20-inch carbon-fiber barrel and micro-length action shave weight without giving up the rigidity Bergara barrels are known for. The rifle ships with both a 5-round and a 10-round detachable magazine, so a shooter can switch between a compact walk-around setup and extended capacity for an afternoon of pest control. A threaded muzzle, drilled-and-tapped receiver, and included 30 MOA rail mean it is ready for a suppressor and a dedicated rimfire optic right out of the box. It is a natural fit for a hunter, rancher, or varmint shooter who wants a serious .22 WMR rifle rather than an entry-level rimfire.
