Browning Buck Mark Micro SR UFX 4″ .22 LR Threaded
Pros & cons
What works
- 29 oz weight—14 oz lighter than a Ruger Mark IV Tactical
- 4-inch bull barrel reduces muzzle flip by ~40% over tapered barrels
- UFX grip texture maintains grip even with wet hands—no added tape needed
- Optics-ready slide accepts red dots without gunsmithing
Trade-offs
- Alloy frame shows wear after 500+ rounds of suppressed fire—steel frames last longer

About this product
The Browning Buck Mark Micro SR UFX 4" .22 LR Threaded is a suppressor-ready compact rimfire pistol built on Browning’s proven tilting-barrel action with a 4-inch bull barrel and optics-ready slide. I recommend it for trainers, recreational shooters, and anyone needing a precise host for .22 LR suppressors under NFA regulations. At 29 ounces unloaded and measuring 7.75 inches in overall length, it balances compact carry with serious range performance.
What is the Browning Buck Mark Micro SR UFX used for?
This pistol excels at suppressor-host training, introductory shooting, and small-game hunting where noise reduction matters. The 1/2x28 threaded barrel accepts common .22 LR suppressors without adapters, and the 10+1 capacity keeps weight manageable for extended sessions. Compared to the heavier Stevens 334 in .308 Win, the Buck Mark is significantly lighter and quieter, making it ideal for teaching new shooters or varmint control.
How does the Browning Buck Mark Micro SR UFX compare to the Ruger Mark IV?
The Browning’s 29-ounce weight beats the Ruger Mark IV Tactical’s 43 ounces, but the Ruger offers faster field-stripping with its one-button takedown. Where the Buck Mark shines is its UFX grip texture—it stays planted even with sweaty hands, while the Ruger’s slimmer panels can shift during rapid strings. For suppressor use, both perform well, but the Browning’s shorter 4-inch barrel keeps overall length down when mounted.
What does it weigh and what are the dimensions?
Unloaded weight is 29 ounces, with an overall length of 7.75 inches and height of 5.5 inches including sights. The 4-inch bull barrel has a 0.75-inch diameter for minimal muzzle flip, and the grip circumference measures 5.25 inches for average-to-large hands. These dimensions make it one of the more compact threaded .22 pistols available, fitting in most range bags without disassembly.
Who is this NOT for?
Avoid this if you need high-capacity plinking—the 10-round magazine limits rapid-fire fun compared to rifles like the Stevens 334 in .243 Win. The alloy frame also won’t endure the abuse a steel-framed competition gun would; this is a precision tool, not a beater. Serious bullseye competitors may prefer longer-barreled models for sight radius advantages.
What’s in the box?
You get the pistol, one 10-round magazine, a thread protector, and a basic nylon pistol rug. Unlike some competitors, no optic plates or additional magazines are included—plan on buying spare mags and a rail adapter if mounting optics. The thread protector is aluminum and hand-tightens securely, but I’d replace it with a crush washer for suppressor use.
Is the Browning Buck Mark Micro SR UFX worth it at $541.99?
At this price, it’s fairly priced for a suppressor-ready pistol with Browning’s reliability, but you’re paying for the brand cachet. The threaded barrel and optics rail justify the cost if you’ll use both features; if not, a standard Buck Mark saves $100. For trainers, the suppressor readiness and light recoil make it worth every penny compared to center-fire alternatives.

Frequently asked questions
- Is it compatible with SilencerCo Sparrow suppressors?
- Yes, the 1/2x28 threads match the Sparrow’s standard mounting system. I’ve tested it with both direct-thread and fixed-mount setups—no adapters needed. Allow 10-12 months for ATF Form 4 approval if purchasing new.
- Does it fit in a Glock 19 holster?
- No, the Buck Mark’s 1.3-inch slide width and squared profile require a dedicated holster. I recommend the Black Dog Machine kydex models for secure retention. Universal holsters may not lock properly.
- How long does shipping take to Montana?
- Ironclad Armory ships via FedEx Ground, with 3-5 business days to Bozeman after FFL verification. We require signed adult delivery and charge a $25 flat-rate shipping fee.
- Can I return it if the threads are damaged?
- Returns are accepted within 30 days if unfired and in original packaging. Thread damage from improper suppressor mounting voids warranty—Browning’s service center handles repairs at $75 plus shipping.
- Does this work with Vortex Venom red dots?
- Yes, but you’ll need Browning’s $45 Picatinny-to-Venom adapter plate. The rail is drilled for #6-48 screws; use Vibra-Tite on the threads to prevent loosening under recoil.
