Description
The Buck Mark has been one of the most trusted .22 LR pistols in the country since 1985, and the Plus URX with its 5.9" barrel is one of the most feature-loaded versions Browning has put out. The frame is CNC-machined from 7075-T6 aircraft-grade aluminum alloy, and the matte gray finish gives it a clean, purposeful look that pairs nicely with the gold-plated trigger — a Buck Mark signature that's more than just cosmetic, it's a reflection of the care Browning puts into the whole package.
Buck Mark Plus URX Sights and Optic Mounting
The sighting setup here is genuinely well thought out. You get a 16-click Pro-Target adjustable rear sight with a white outline and a green fiber-optic front sight that picks up light fast. Both sit on a full-length Picatinny rail that runs the length of the slide, so dropping a micro red dot or reflex sight on is straightforward if you want to go that route. A lot of .22 pistols force you to choose between iron sights and optics. This one has you covered either way right out of the box.
What Makes the URX Grip Work
URX stands for Ultragrip RX, and the soft nitrile rubber with built-in finger grooves does a better job of locking your hand in place than most grips in this category. The pistol has a comfortable grip angle that feels natural on the draw and keeps muzzle flip minimal during rapid strings. At around 35 oz., the Plus URX has enough weight to settle into your hand and stay there, which makes follow-up shots easy and genuinely enjoyable to shoot.
The 5.9" barrel comes threaded at 1/2"-28 with a muzzle brake included, making this one of the most suppressor-friendly rimfire pistols at this price point. The blowback action cycles smoothly, the last round holds the bolt open so you always know when you're empty, and the single-stack 10-round magazine loads easily thanks to the assist button on the baseplate. Made in the USA.

Frequently Asked Questions
Is the Browning Buck Mark Plus URX suppressor ready?
Yes. The 5.9" barrel is threaded at 1/2"-28, which is the standard pitch for most .22 LR suppressors on the market. A muzzle brake is included from the factory and threads directly onto those same threads. When you're ready to run a can, just swap the brake out for your suppressor.
Can I mount a red dot on the Buck Mark Plus URX?
Absolutely. The slide features a full-length Picatinny rail that accepts micro red dots and reflex sights using standard mounts. The pistol also comes with a fully functional Pro-Target adjustable rear and green fiber-optic front sight, so you have solid irons to fall back on if you prefer to keep it simple.
How does the URX grip compare to other Buck Mark grip options?
URX stands for Ultragrip RX, which is Browning's soft nitrile rubber grip panel with molded-in finger grooves. It tends to be the most popular option in the lineup for range use because it grips well even with sweaty hands and the finger grooves help with consistent hand placement. If you prefer wood, Browning also offers UDX models with walnut-style panels.
What kind of .22 LR ammo runs best in the Buck Mark Plus URX?
Like most .22 blowback pistols, the Buck Mark runs most reliably with standard and high-velocity loads like CCI Mini-Mag or Federal Auto Match. Very low-powered subsonic ammo can occasionally cause cycling issues in any blowback-operated rimfire pistol. For suppressed use, quality subsonic loads from established brands generally work well once the gun is broken in.
What is the Buck Mark Plus URX good for?
It's a genuinely versatile rimfire pistol. It works great for casual range days and plinking, but the adjustable sights, fixed barrel, and Picatinny rail also make it a solid option for rimfire competition. The threaded barrel and included muzzle brake add value for anyone interested in running a suppressor. It's also widely used for new shooter training since .22 LR is affordable and the pistol is easy to control.
Does the Browning Buck Mark have a last-round bolt hold-open?
Yes, the Buck Mark locks the bolt back after the last round is fired, giving you a clear visual indicator that the magazine is empty. This is a practical feature for both range use and competition. The magazine also features an assist button on the baseplate that makes loading all 10 rounds much easier.
