Proof Research Latitude LOP 22LR Sendero 18″ Adjustable LOP

The Proof Research Latitude is a precision-oriented rimfire rifle built around a carbon fiber-wrapped, cut-rifled barrel and the Zermatt Arms RimX action. It combines a lightweight carbon-fiber stock with an adjustable length-of-pull and cheek height for a custom fit. The platform is intended for precision rimfire work — competition, training, and accurate small-game applications — and ships test-fired with a guaranteed accuracy standard. Controls and ergonomics reflect a right-hand bolt action layout with a detachable box magazine.
