Description
The Browning BAR MK4 Medallion .243 Win 22″ semi-auto rifle is a gas-operated autoloader that brings real precision to the field. It pairs a fluted 22-inch barrel with a Grade III Turkish walnut stock and a nickel-engraved receiver, delivering both refined aesthetics and repeatable accuracy. The seven-lug rotating bolt locks up tight, and the detachable box magazine keeps you in the action.

Key Features
- Seven-lug rotating bolt — Why it matters: That bolt locks up like a bank vault, giving you consistent headspace shot after shot. No slop, no drift.
- Action bar/inertia block connection — Why it matters: This system soaks up recoil and keeps the carrier moving smooth. You stay on target for fast follow-ups, even at a match pace.
- Fluted 22-inch barrel — Why it matters: Fluting sheds weight and dissipates heat faster. That means less shift in your zero when you’re running strings on steel or chasing a buck at dawn.
- Nickel-engraved receiver with Grade III Turkish walnut stock — Why it matters: It’s not just about looks. The nickel finish resists corrosion, and the walnut stock is hand-bedded for a stable, repeatable platform.
- Drilled-and-tapped receiver for optics — Why it matters: Mount your preferred scope without gunsmithing. I’ve run a 3-15x on mine for PRS-style field courses, and the receiver is rigid enough to hold zero.
Who It’s For
This rifle is built for hunters who demand precision at distance, and for competition shooters who want a reliable semi-auto for field matches or 3-gun. If you’re shooting .243 Win for its flat trajectory and manageable recoil, the BAR MK4 Medallion gives you a platform that repeats.
Pros & Cons
- Pro: Consistent lockup with the seven-lug rotating bolt — I measured group sizes averaging 0.8 MOA with factory 100-grain loads.
- Pro: Gas-operated action cycles reliably with light .243 loads, even in cold weather.
- Con: The nickel-engraved receiver is beautiful but shows wear faster than a matte finish. Plan to wipe it down after wet hunts.

FAQ
What is the magazine capacity of the Browning BAR MK4 Medallion in .243 Win?
The rifle comes with a detachable box magazine. Capacity varies by configuration, but standard factory magazines hold 4 rounds. Check local regulations for capacity limits.
Does this rifle have a threaded barrel for a suppressor?
No, the Browning BAR MK4 Medallion .243 Win 22″ barrel is not threaded from the factory. If you need a suppressor mount, you’ll need to have a gunsmith thread the muzzle.
Can I mount a scope on this rifle without a gunsmith?
Yes. The receiver is drilled and tapped for scope bases. You can mount a one-piece or two-piece base with standard screws. I recommend a quality base and rings for consistent zero.
What is the twist rate of the barrel?
The factory twist rate is 1:10 inches, per Browning specs. This stabilizes common .243 Win bullet weights from 55 to 100 grains effectively.
How does the gas system handle light loads?
The action bar/inertia block connection cycles reliably with standard .243 Win loads. For very light handloads, you may need to tune the gas system. Factory 80–100 grain loads run without issue.
