The Browning AB3 .300 Win Mag rifle (brand part no. 035841229), wrapped in Mossy Oak Bottomland camouflage, brings Browning’s AB3 platform to a long-range magnum cartridge over a weather-resistant composite stock. The 26-inch barrel is free-floated and threaded for the included radial-style muzzle brake, which takes a meaningful bite out of the .300 Win Mag’s recoil. A short 60-degree bolt lift keeps cycling fast and a shooter’s hand clear of scope turrets, and a detachable box magazine makes follow-up shots quick to load. It is built for a hunter chasing elk, mule deer, or other large game at distance who wants magnum reach without giving up a manageable, lightweight rifle.
