Description
The BAR has been the standard for semi-auto hunting rifles since 1967, and the MK4 Hunter is the latest evolution of a design that traces its roots all the way back to John Browning himself. This version is chambered in 308 Win and pairs a 22 inch fluted, non-reflective matte blued barrel with a lightweight aluminum alloy receiver that keeps the whole package at a very manageable 7 pounds 2 ounces. The short-stroke gas piston system cycles smoothly and soaks up a noticeable amount of felt recoil, which is a big part of why so many hunters swear by the BAR for quick, controlled follow-up shots on big game.
Why the BAR MK4 Hunter Still Sets the Bar
At the core of the action is a seven-lug rotating bolt that locks directly into the barrel, giving you a tight breech-to-chamber fit and accuracy that holds its own against plenty of bolt guns. The action bar and inertia block linkup cuts down on barrel vibration, and an integral buffering system reduces wear on the operating parts over years of use. Feeding comes from a 4 round detachable box magazine on a hinged floorplate, so you can top off from above or drop the whole assembly to swap mags. The receiver is drilled and tapped for scope mounts, and Browning kept the same base hole spacing the BAR has used for decades, so mounting options are everywhere.
Grade II Walnut That Fits You, Not the Other Way Around
The oil-finished Grade II Turkish walnut stock is the kind of wood that makes this rifle stand out at the range, and it does more than look good. Included shims let you adjust cast on/off and drop at the comb so your eye lines up naturally behind your optic, and the Inflex recoil pad takes the sting out of a full day of shooting. With a 43.4 inch overall length and 13.75 inch length of pull, the MK4 Hunter handles quick in the deer woods and points like a rifle should. If you want walnut, real accuracy, and fast second shots in one package, this is the one.

Frequently Asked Questions
How accurate is the Browning BAR MK4 Hunter in 308?
Very respectable for a semi-auto hunting rifle. Independent range testing has produced three-shot groups right around an inch with quality 150 grain hunting loads, which is plenty for big game at practical distances. The seven-lug bolt locking directly into the barrel and the vibration-reducing action bar design are a big part of that consistency.
Does the BAR MK4 Hunter come with sights or a scope rail?
No, this model ships without sights or a rail. The alloy receiver is drilled and tapped for scope bases, and Browning kept the same hole spacing the BAR has used for generations, so bases and mounts are easy to find. Plan on adding an optic before heading to the field.
How does the magazine work on the BAR MK4?
It uses a detachable box magazine attached to a hinged floorplate, a design carried over from earlier BARs. You can swing the floorplate open to top off rounds without removing anything, or detach the magazine entirely for a quick swap. Capacity is 4 rounds in 308 Win, plus one in the chamber.
Can I adjust the fit of the walnut stock?
Yes. The Grade II Turkish walnut stock is shim-adjustable for both cast on/off and drop at the comb, so you can fine tune how the rifle mounts and where your eye sits behind the scope. Combined with the Inflex recoil pad and the recoil-softening gas piston system, it makes for a comfortable rifle even during long range sessions.
