The Howa Mini Action rifle in 6.5mm Grendel (brand part no. HMA70623+) puts an efficient, accurate cartridge into a compact bolt action scaled specifically for shorter rounds. Howa built this Mini Action receiver to save weight and length compared to a full-size action, and the 6.5mm Grendel cartridge is known for excellent ballistic coefficients and mild recoil at extended range. A 20-inch threaded barrel keeps the package short and ready for a suppressor, while the OD Green finish sets it apart visually from standard black builds. The 5+1 detachable magazine and compact action make this rifle a strong choice for hunters and long-range shooters who want a lighter overall package.
