About this product
The Browning Buck Mark Plus UDX 5.50'' .22 LR Stainless is a single-action rimfire pistol built for accurate target shooting and reliable field use. It pairs a target-crowned stainless barrel with a matte black aluminum receiver, giving you a durable, well-balanced handgun right out of the box. This is the factory configuration as provided by Browning, ready for your next range trip or plinking session.

- Target-crowned stainless barrel – Why it matters: The crown protects the muzzle and helps deliver consistent accuracy shot after shot, especially with .22 LR ammo.
- Crisp single-action trigger – Why it matters: A clean, predictable trigger pull lets you focus on sight alignment and follow-through, reducing flyers.
- Slab-side barrel design – Why it matters: Flat-sided barrels reduce weight and give the pistol a distinctive look while maintaining rigidity for repeatable zero.
- Black laminate grips – Why it matters: Laminate wood resists moisture and temperature changes better than standard wood, so your grip stays secure in damp or hot conditions.
- Matte black aluminum receiver – Why it matters: Aluminum keeps the overall weight manageable, and the matte finish cuts glare so you stay focused on the target.
Who it's for: This pistol suits new shooters looking for a reliable .22 LR to build fundamentals, as well as experienced plinkers who want a precise, low-recoil handgun for extended range sessions. It's also a solid choice for small-game hunting or pest control around the property.
Pros: Accurate barrel, excellent trigger, lightweight receiver, durable grips. Cons: The single-action-only design means you must manually cock the hammer for the first shot, which may slow down follow-ups compared to a double-action rimfire.

Is the Browning Buck Mark Plus UDX 5.50'' .22 LR stainless reliable with standard velocity ammo?
Yes, it cycles reliably with most standard-velocity .22 LR rounds, as long as they're clean and well-lubricated. Some bulk-pack ammo may cause occasional feed issues, but that's common with any rimfire pistol. Stick with high-velocity or match-grade ammo for best results.
What is the barrel twist rate on this model?
According to Browning specs, the Buck Mark Plus UDX uses a 1:16-inch twist rate, which stabilizes standard 40-grain .22 LR bullets well. Heavier subsonic loads may still shoot accurately, but performance can vary by brand.
Does the Buck Mark Plus UDX come with adjustable sights?
Yes, it features a fully adjustable rear sight for windage and elevation. The front sight is a fixed blade with a red fiber-optic insert for quick acquisition in varying light.
Can I mount a red dot on this pistol?
The receiver is not drilled and tapped for optics from the factory, but aftermarket mounts are available from companies like Tactical Solutions. If you want a red dot out of the box, look at the Buck Mark Plus Vision model.
