The G1 frame carries the classic factory cougar motif on both sides, a hallmark of early Contender aesthetics. This carbine configuration pairs blued steel with a satin walnut Monte Carlo stock and walnut carbine forend, delivering a traditional look and solid handling. Length of pull is 13.5 inches, and a black rubber buttplate caps the stock.
Built in 1989 in the USA, this single-shot, break-open .223 Rem carbine has a 21-inch blued barrel and a capacity of one round. The front sight is a ramped post, and no rear iron sight is visible with the scope base installed, aligning the rifle for scope use with the included rings.
The Contender G1’s hammer-mounted centerfire/rimfire firing-pin selector and its modular quick-change barrel system allow the frame to accept a wide range of barrels. This example is configured as a .223 Rem carbine, combining compact handling with the well-known Contender interchangeability.
The action is single-action only, and the steel frame/receiver wears a consistent blued finish. The stock set features a pistol-grip profile and Monte Carlo comb for a steady cheek weld, complementing scoped shooting with the installed Weaver-style base and rings.
