Features

The Browning Buck Mark Micro Bull UFX SR (.22 LR) is a compact, suppressor‑ready rimfire pistol built for accuracy, control, and modern adaptability. Its 4" matte‑blued bull barrel provides excellent stability and heat resistance, while the 1/2x28 threaded muzzle—with included thread protector—makes it ideal for running a suppressor or compensator. The aluminum‑alloy receiver features slide serrations and an integrated Picatinny rail, giving shooters the option to mount optics or accessories with ease. For those who prefer irons, the pistol includes a Pro‑Target white‑outline adjustable rear sight paired with a bright green fiber‑optic front sight, offering a crisp, highly visible sight picture.

Ergonomics are a standout thanks to the rubber‑overmolded UFX grips, which provide a secure, ambidextrous hold for extended range sessions. At 1 lb 13 oz and 8" overall, the Micro Bull UFX SR is lightweight, well‑balanced, and easy to control for new and experienced shooters alike. A 10‑round proprietary magazine, thumb safety, and clean‑cycling semi‑auto action round out a platform ideal for plinking, training, and precision rimfire work. As a 2026 SHOT Show Special, it ships with a pistol rug, adding a practical touch to a feature‑rich, ready‑to‑shoot package.
