BROWNING BUCK MARK PLUS UDX | .22 LR | 5.5 in | MFG# 051428490

The Browning Buck Mark Plus UDX is a precision-oriented .22 LR semi-automatic pistol built on a machined aluminum alloy receiver with a slab-side steel barrel. It features a 5.50 inch barrel, TruGlo fiber-optic front sight and a Pro-Target adjustable rear sight, and is configured to meet California compliancy with a 10+1 capacity. The pistol pairs target-grade ergonomics with a single-action trigger and textured brown laminate finger-groove grips for consistent hand placement.

For an optic under $1,000 that complements the Buck Mark Plus UDX’s target focus, a compact red-dot such as the Vortex Venom (micro reflex) provides a low-profile mounting solution and quick target acquisition while preserving the pistol’s sight radius.

Typical applications for this pistol include precision rimfire target shooting and small-bore competition/training.
