Description
The Buck Mark Hunter Varmint SR is Browning's most capable rimfire pistol, introduced as a 2026 SHOT Show Special and built from the ground up for shooters who want more than a standard plinking gun. The heart of it is a 10.5" special-contour bull barrel machined with suppressor-ready 1/2-28 threading, giving you the option to run it can-ready right out of the box without any adapters or modifications. The aluminum frame is precision-machined from aircraft-grade alloy and finished in matte black, and the whole package carries the single-action, straight-blowback reliability that's made the Buck Mark one of the most trusted .22 platforms since 1985.
What the Buck Mark Hunter Varmint SR Gets Right
That extra barrel length isn't just for looks. A longer bull barrel adds muzzle velocity, reduces muzzle flip, and gives you a longer sight radius before you even mount an optic. The full-length Picatinny top rail runs the entire length of the slide, making it easy to drop on a red dot or a compact low-power scope for precise shots at distance. Below the barrel, a second Picatinny rail handles lights, lasers, or a bipod adapter if you're shooting from a rest. The flat trigger shoe is a nice detail too, the kind of thing you typically see on purpose-built target guns rather than general-use pistols. Rosewood laminate target grips with a Buckmark inlay round out the package with a comfortable, controlled feel that promotes a natural thumbs-forward hold.
Running Suppressed on the Buck Mark Varmint SR
The blowback design on the Buck Mark actually runs very well with a suppressor attached. The straight-blowback operating system doesn't rely on gas adjustments or a piston, so there's no tuning needed when you thread on a can. The 1/2-28 thread pattern is the standard pitch for .22 LR suppressors, so you're not locked into any specific brand. Running subsonic .22 LR through it with a suppressor is about as quiet and enjoyable as rimfire shooting gets. Note that this pistol ships with a thread protector to cover the muzzle when shooting without a suppressor. Keep the gun clean since rimfire carbon buildup is real, and the Buck Mark performs best with regular maintenance.
Capacity is 10+1 from a single-stack detachable magazine, and the magazine release sits right next to the trigger guard for easy access. The manual thumb safety is large and positive, and the slide release is reachable with either hand. For anyone doing serious rimfire work whether that's running squirrels out of a wood lot, paper punching at distance, or just building a suppressor host they'll actually enjoy shooting, the Hunter Varmint SR is a purpose-built tool that earns its price.

Frequently Asked Questions
Is the Buck Mark Hunter Varmint SR truly ready to run a suppressor out of the box?
Yes. The 10.5" barrel is threaded at 1/2"-28, which is the standard pitch for the vast majority of .22 LR suppressors on the market. You don't need any adapters. The Buck Mark's straight-blowback operating system also runs cleanly with a suppressor attached since there's no gas port or piston system to worry about adjusting.
What optics can I mount on the Buck Mark Hunter Varmint SR?
The full-length Picatinny top rail accepts virtually any red dot, holographic sight, or compact rimfire scope that uses a Picatinny or Weaver-compatible mount. A red dot is the most popular choice for this type of pistol, giving you fast target acquisition for small game or precise aiming on paper targets at distance. The rail runs the full length of the slide, so you have plenty of room to position your optic and find a comfortable eye relief.
How does the 10.5" barrel length affect performance compared to a standard Buck Mark?
The longer bull barrel adds measurable muzzle velocity over shorter Buck Mark variants, which matters when you're pushing .22 LR for small game or precision use. The extra weight up front also reduces muzzle rise, making follow-up shots faster and easier to control. The longer sight radius is a bonus too, though most people running this model will pair it with an optic anyway.
What is the under-barrel Picatinny rail for on the Varmint SR?
The lower rail gives you the option to attach accessories like a light, laser sight, or a bipod adapter. For varmint and small game use, a small pressure-activated light or a laser can be genuinely useful. A bipod adapter is also a popular addition if you plan on shooting from a bench or prone position for extended-range precision work.
How reliable is the Buck Mark platform and how often does it need cleaning?
The Buck Mark has a well-earned reputation for reliability built up over decades of production. That said, like all rimfire firearms, it benefits from regular cleaning since .22 LR ammunition leaves significantly more fouling than centerfire ammo. Running it dirty for too long can cause feeding or extraction issues, so a basic clean every few hundred rounds is a good habit to keep it running its best.
Is this pistol good for left-handed shooters?
The Buck Mark's manual thumb safety is right-side only, which is worth knowing if you're a lefty. The magazine release and slide release are both accessible from either side, so the controls aren't completely one-sided, but the safety is the one control that's specifically set up for right-hand use. Left-handed shooters can still operate it effectively, it's just something to be aware of before buying.
