About this product
The Browning Buck Mark Micro Bull 22 LR 4.4 in Blued RMSc is built for urban shooters who need a rimfire pistol that pulls double duty—range practice and home defense training. The 4.4-inch bull barrel delivers the weight and stability you want for tight groups, while the matte blued finish sheds glare in low-light apartment hallways. The slide is drilled and tapped for RMSc optics, so you can mount a red dot without a gunsmith. Per Browning specs, this pistol ships with a Pro-Target adjustable rear sight and a green fiber-optic front sight for fast target acquisition. The threaded muzzle (1/2-28 TPI) is suppressor-ready, and the UFX ambidextrous grips with FDE rubber overmolding keep your support hand locked in during rapid fire. At $689.99, it’s a rimfire trainer that scales from the range to the nightstand.

Key Features
- 4.4-Inch Bull Barrel – The extra weight up front reduces muzzle flip and keeps your sight picture steady through a 10-round string. Why it matters: You’ll shoot tighter groups at 25 yards without fighting the gun.
- RMSc Optic-Ready Slide – Direct-mount your red dot without adapters. Why it matters: Faster target transitions in a defensive scenario—no lost time looking for irons.
- Suppressor-Ready Threaded Muzzle – 1/2-28 TPI with a thread protector. Why it matters: Run a can in your apartment without blowing out your ears or alerting the whole floor.
- UFX Ambidextrous Grips with FDE Overmolding – Rubber texture wraps the full circumference. Why it matters: Sweaty hands after a long range session won’t slip, and the FDE color adds contrast against dark holsters.
- Pro-Target Adjustable Rear Sight & Green Fiber-Optic Front – Windage and elevation adjustments with a high-visibility front dot. Why it matters: Zero for your favorite bulk ammo and see the dot in any indoor lighting.
Who It’s For
This pistol is for the city dweller who wants a rimfire trainer that mirrors a centerfire carry gun. If you live in a studio or one-bedroom and need something quiet enough for indoor practice but capable enough for home defense training, the Micro Bull fits. The ambi controls and optic cut make it a solid choice for left-handed shooters or anyone who runs a red dot on their EDC. It’s not a pocket pistol—it’s a range companion that doubles as a suppressor host.
Pros & Cons
- Pro: The bull barrel gives you the balance of a full-size gun in a compact frame.
- Pro: RMSc cut means you can mount a dot without spending extra on milling.
- Pro: Threaded barrel is ready for your suppressor out of the box.
- Con: The 36-ounce weight is heavy for a .22—you’ll feel it after a 200-round session, but that weight also tames recoil.
Comparison vs. Competitors
| Model | Barrel Length | Optic Ready | Weight | MSRP |
|---|---|---|---|---|
| Browning Buck Mark Micro Bull | 4.4 in | Yes (RMSc) | 36 oz | $689.99 |
| Zev Technologies OZ-22 | 4.0 in | Yes (RMRcc) | 32 oz | $749.99 |
| Agency Arms 22LR (Custom Build) | 4.5 in | Yes (RMR) | 34 oz | $899.00 |
The Zev OZ-22 is lighter but uses a different optic footprint (RMRcc), meaning you’ll need an adapter plate for RMSc dots. The Agency Arms build costs over $200 more and requires a custom order. The Browning gives you a threaded barrel standard—Zev charges extra for it.
FAQ
What optics fit the Browning Buck Mark Micro Bull RMSc cut?
The slide is drilled and tapped for the RMSc footprint. Direct-mount optics include the Shield RMSc, Holosun 407K/507K, and Swampfox Sentinel. You can also use an adapter plate for RMRcc or Docter/Noblex footprints, but it will raise the deck height.
Is the barrel threaded for suppressors?
Yes—1/2-28 TPI threading with a thread protector installed. It’s compatible with most .22 LR suppressors like the Dead Air Mask or SilencerCo Sparrow.
Can left-handed shooters use the ambidextrous controls?
Yes. The UFX grip is ambidextrous, and the manual safety is reversible. The magazine release is also ambi-friendly—you can reach it with your trigger finger or support thumb.
What is the magazine capacity?
The Buck Mark Micro Bull ships with one 10-round magazine. Spare magazines are available from Browning and aftermarket suppliers.
