The Browning BAR MK4 Hunter is a semi-auto centerfire rifle chambered in 7mm Rem Mag. It uses a gas piston operating system with a rotating bolt, and it feeds from a detachable box magazine holding 3 rounds plus one in the chamber. The rifle has a 24-inch fluted barrel and a matte blued aluminum alloy receiver paired with a black composite stock.

Owners of the BAR MK4 line generally describe the action as smooth and reliable once broken in, with the gas piston system keeping the rifle running clean between range trips and hunts. Some note that a new BAR benefits from a short break-in period before cycling feels fully consistent, and a few mention the detachable magazine as a welcome change from older BAR generations.

In the field, the shim-adjustable stock and the composite build get consistent praise for letting shooters dial in fit without sending the rifle to a gunsmith. The recoil pad and overall balance of the Hunter Composite are frequently cited as making the 7mm Rem Mag chambering more manageable to shoot from field positions than expected for a magnum autoloader.

On value, opinions split a bit: buyers coming from bolt guns sometimes balk at the price relative to a comparable bolt-action rifle, while semi-auto hunters see it as reasonable for a proven autoloading platform. The drilled and tapped receiver makes optic mounting straightforward, which owners appreciate when setting the BAR MK4 up for their preferred glass.
