Browning Buck Mark Micro Bull 22 LR 4.4 in Blued RMSc

Description

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.
