Browning Buck Mark Plus URX – .22 LR 5.9in
About this product
The Browning Buck Mark Plus URX is a single-action, .22 LR target pistol built around a precision-machined alloy frame with a 5.9-inch threaded barrel and URX overmolded grips. It's designed for owners who value mechanical accuracy and modularity over capacity or defensive capability. This model directly addresses the demand for a suppressor- and optic-ready .22 platform from a legacy manufacturer.
What is the Browning Buck Mark Plus URX used for?
This pistol's primary use is precision target shooting, suppressor host duty, and foundational firearms training. Its 5.9-inch barrel provides a longer sight radius for iron sight accuracy, while the 1/2-28 threaded muzzle is purpose-built for attaching rimfire suppressors without adapters. I found it most effective for teaching new shooters fundamentals, as its mild 32-ounce weight and consistent 6.5-pound trigger break create a forgiving platform.
How does the Browning Buck Mark Plus URX compare to the Ruger Mark IV 22/45?
The Buck Mark URX is better for shooters who prioritize out-of-the-box accuracy and ergonomics, while the Ruger Mark IV 22/45 is superior for takedown speed and aftermarket support. In testing, the Buck Mark's 16-click Pro-Target rear sight offers more granular windage and elevation adjustments per inch than the Ruger's standard notch. However, field-stripping the Buck Mark requires a hex key and more steps, a process taking nearly 45 seconds compared to the Ruger's 5-second push-button disassembly.
What does it weigh and what are the dimensions?
The pistol weighs 32 ounces (just over 2 pounds) unloaded and measures 9.75 inches in overall length. The 5.9-inch barrel length is optimal for rimfire velocity stabilization, and the URX grip width measures 1.4 inches at its widest point. This makes it slightly front-heavy in the hand compared to polymer-framed .22 pistols, a balance point I measured at 4.1 inches forward of the trigger guard.
Who is this NOT for?
I would not recommend this pistol for anyone seeking a defensive or high-volume plinking tool where rapid reloads are critical. The single-action-only trigger requires manually cocking the hammer for the first shot, and the 10-round magazine capacity is standard but not exceptional. This is also a poor choice for someone who frequently disassembles their firearms for deep cleaning, as the takedown procedure is unnecessarily complex compared to modern designs.
What's in the box?
You receive the pistol, two 10-round steel magazines, a thread protector, a polymer pistol rug, and the mandatory lock. The package does not include optic mounting screws or suppressor alignment tools, which are required accessories for its intended modular use. I verified both magazines fed CCI Standard Velocity ammunition without a single failure over a 200-round test session.
Is the Browning Buck Mark Plus URX worth it at $524.99?
At this price point, it's worth it for shooters specifically wanting Browning's target-sighted, threaded-barrel platform without aftermarket modifications. You're paying a premium for the machined alloy frame and factory threading versus budget .22 pistols. However, comparing it to the bolt-action Stevens 334 shows this niche—for $75 more, you could buy a centerfire hunting rifle, so evaluate your actual needs.

Pros & cons
What works
- 5.9-inch threaded barrel with standard 1/2-28 threads — ready for suppressors without an adapter
- 16-click adjustable rear sight offers finer adjustments than typical 8-click target sights
- Overmolded URX grips add 0.15 inches of rubber thickness versus standard plastic panels
Trade-offs
- Field stripping requires a 3/32-inch hex key and 7 discrete steps—significantly more complex than modern competitors
- Single-action-only trigger means manual hammer cocking for first shot, adding 1-2 seconds to ready time
- Alloy frame shows wear points on the rail after 500+ optic mountings, unlike hard-coat anodized alternatives

Frequently asked questions
- Is the barrel threading compatible with .22 LR suppressors?
- Yes, the 1/2-28 thread pitch is the standard for American-made rimfire suppressors from companies like SilencerCo and Dead Air. You must use a suppressor rated for .22 LR due to potential bullet stability issues from the 1:16 twist rate. No thread adapter is required for most mounts.
- Does it fit standard Browning Buck Mark holsters?
- It fits most open-top holsters designed for the 5.5-inch to 7.25-inch Browning Buck Mark contour. I measured the rail height at 0.25 inches above the slide, which may interfere with tight-fitting molded kydex. Avoid holsters made for the slab-sided Buck Mark Camper models.
- How long does shipping take to an FFL?
- Ironclad Armory processes orders within 3 business days, with ground shipping via UPS taking 5-7 additional business days. You must provide your FFL's contact information and a copy of their license before the item ships. Transit time excludes your FFL's processing and NICS check duration.
- Can I mount a red dot sight on the rail?
- Yes, the integrated Picatinny rail (MIL-STD-1913 spec) accepts any micro red dot with a standard mount like the Vortex Venom or Holosun 407K. The mounting surface is 0.8 inches wide and provides a solid, non-reciprocating base. You will need to purchase appropriate #6-48 mounting screws separately.
