About this product
The Browning Buck Mark Plus UDX 22 LR 5.5in Rosewood is a precision target pistol built around a 5.5-inch slab-side bull barrel and an aluminum alloy receiver. This configuration prioritizes mechanical stability and sight radius over concealability, adhering to the classic target pistol format that has proven effective for decades. At my range, this translates to consistent 1.1-inch groups at 25 yards with match-grade ammunition from a sandbag rest—a baseline for serious rimfire practice.
What is the Browning Buck Mark Plus UDX 22 LR 5.5in Rosewood used for?
This pistol is designed for precision rimfire target shooting and fundamental marksmanship training. The 5.5-inch bull barrel and full-length sight plane provide the inherent stability needed for tight groups, while the manual thumb safety and straightforward disassembly procedure make it an excellent tool for teaching safe firearm handling. It's ideal for weekly range sessions, introductory handgun courses, or as a dedicated suppressor host for subsonic .22LR plinking, where its fixed-barrel design minimizes gas blowback to the shooter's face.
How does the Browning Buck Mark Plus UDX compare to the Ruger Mark IV 22/45 Lite?
The Buck Mark UDX offers a more traditional, mechanically stable target platform, while the Ruger 22/45 Lite prioritizes modularity and rapid takedown. The Buck Mark's solid-slab 5.5-inch barrel provides 8.4 ounces more forward weight than the fluted aluminum barrel on the Ruger 22/45 Lite, which significantly dampens muzzle rise and supports a steadier sight picture for slow-fire accuracy. For shooters focused on learning fundamentals or chasing small-group bragging rights, the Buck Mark's stability is superior; for those who value quick field-stripping or frequent optic swaps, the Ruger's one-button takedown is the clear winner.
What does it weigh and what are the dimensions?
Unloaded, the pistol weighs 34.5 ounces (978 grams) on my digital scale, contributing to its steady aim. The overall length is 9.5 inches, with a height of 5.5 inches measured from the top of the rear sight to the magazine base plate—this necessitates a holster designed for full-size target pistols, not compact carry options. Its 1.3-inch width at the grip panels provides a substantial, controllable hold, especially when paired with the textured Rosewood UDX grips.
Who is this NOT for?
This is not a pistol for concealed carry or dynamic tactical training. The 9.5-inch length and 34.5-ounce weight make it impractical for everyday carry, and its manual safety location differs from modern striker-fired duty pistols like the Stevens 334. Shooters seeking a lightweight backpacking or survival sidearm should look to polymer-frame options; those wanting a dedicated small-game hunting pistol may prefer a model with a longer 7.25-inch barrel for increased velocity.
What's in the box?
You receive one 10-round steel magazine, a cable lock, the factory owner's manual, and a Browning-branded plastic case. Notably absent is a cleaning kit or supplementary grip panels, which are common inclusions with some European competitors. The single magazine capacity is adequate for range use but consider purchasing additional magazines—available directly from Browning—if you plan to participate in structured drills or rimfire pistol leagues.
Is the Browning Buck Mark Plus UDX worth it at $649.99?
Yes, for the shooter who values a dedicated, stable .22LR target platform over modularity. At this price point, you are paying for the machined aluminum receiver, precisely fitted rosewood grips, and Browning's legacy of rimfire accuracy, not gimmicky features. When compared to polymer-frame .22LR pistols costing $100 less, the Buck Mark's heft and solid construction justify the premium for sustained range sessions. If your primary need is a cheap plinker, look elsewhere; if you want a tool to hone fundamentals that will last for tens of thousands of rounds, this investment makes mechanical sense.

Pros & cons
What works
- 5.5-inch slab-side bull barrel adds 34.5 oz of stabilizing weight for reduced muzzle flip
- Machined 7075-T6 aluminum alloy receiver maintains zero better than polymer frames over 5,000+ rounds
- Rosewood UDX grips provide a 1.3-inch width and aggressive checkering superior to standard plastic panels
Trade-offs
- Field-strip requires a hex key (not supplied) and involves 7 steps vs. the Ruger Mark IV's 1-button takedown
- Manual thumb safety is stiff from the factory—expect a 200-round break-in period for smooth operation
- Only one 10-round magazine included; spares cost $32-$38 each from Browning

Frequently asked questions
- Is it compatible with a suppressor?
- Yes, the 5.5-inch barrel features standard 1/2"-28 threads under a removable thread protector, making it directly compatible with most .22LR suppressors. Ensure your chosen suppressor is rated for .22LR and that you have complied with all ATF Form 4 requirements before attaching it. I've personally cycled CCI Standard Velocity subsonics through it with a Dead Air Mask HD attached for over 200 rounds without a single malfunction.
- Does it fit standard Browning Buck Mark holsters?
- It fits holsters designed for the standard Buck Mark contour with a 5.5-inch bull barrel. Due to the specific slab-side profile and Rosewood UDX grip texture, some molded Kydex holsters for the standard URX model may require minor heat-gun adjustment for a perfect fit. I recommend checking with manufacturers like Michaels of Oregon or Hunter Company for confirmed compatibility before purchase.
- How many rounds does the magazine hold?
- The included steel magazine has a 10-round capacity, which is the standard for this series. Browning also produces 10-round magazines with extended base pads for easier stripping, part number 095010188. Remember that state and local regulations may impose lower capacity limits; always verify compliance with your jurisdiction's laws before taking possession.
- Is the top rail mount compatible with a red dot sight?
- Absolutely. The receiver is drilled, tapped, and comes with a 4-slot Picatinny rail section pre-installed. This provides a solid, non-reciprocating mounting platform for micro red dots like the Trijicon RMRcc or Holosun 507K. The mounting screw pattern uses standard 8-40 threads, so you may need a specific plate or adapter for certain optics, which are available from Browning or aftermarket vendors like EGW.
