The Browning 039009218 BAR MK4 Medallion in .308 Win is a gas-operated semi-automatic rifle built on a lineage that traces back to John M. Browning’s original 1918 design. This model features a 22” polished blued fluted barrel, a satin nickel engraved aluminum alloy receiver that is drilled and tapped for optics, and a Grade III Turkish walnut stock with an adjustable shim system. The 4+1 detachable box magazine and Inflex recoil pad round out a package intended for serious hunting and long-range shooting.

Key Features
- Gas-operated autoloader with action bar/inertia block connection — reduces barrel vibrations during the firing cycle, which directly improves shot-to-shot consistency and overall accuracy.
- Grade III Turkish walnut stock with adjustable shim system — allows the shooter to modify cast on/off and drop at comb for a precise cheek weld, critical for repeatable accuracy.
- Satin nickel engraved receiver, drilled and tapped — the corrosion-resistant finish and factory-tapped holes simplify mounting optics without aftermarket gunsmithing.
- Polished blued fluted barrel, 22 inches — fluting reduces weight and increases surface area for faster heat dissipation, maintaining accuracy during extended strings.
- Inflex recoil pad and detachable box magazine — the pad redirects recoil away from the shooter’s face, and the 4+1 magazine enables rapid reloads in the field.
Who It’s For
Law enforcement personnel who need a reliable, fast-follow-up semi-auto for patrol rifle applications. Military shooters who appreciate a proven gas system and the ability to mount optics without extra modifications. Serious hunters who demand sub-MOA potential from a .308 platform with an adjustable stock.
Pros & Cons
- Pro: The action bar/inertia block connection minimizes barrel vibrations, a design detail that contributes to the rifle’s reputation for accuracy. Per Browning specs, the Inflex recoil pad reduces felt recoil by up to 25% compared to standard pads.
- Con: The detachable box magazine capacity is limited to 4+1, which may be a drawback for shooters accustomed to higher-capacity magazines in a .308 semi-auto.
