Every Buck Mark starts out as a solid piece of aircraft-grade 7075 aluminum alloy, and then is CNC machined to exacting tolerances. The straight blow back design offers simplicity and reliability. The crisp single-action trigger, hand-reamed chamber, target crowned barrel and adjustable sights mean the Buck Mark Camper comes ready straight from the box. Comfortable and secure in any condition, Ultra grip RX have ambidextrous finger grooves, laser stippling and a wave pattern to form an Ergonomic Interactive Surface (EIS) putting hands in the same place on the grip for every shot, resulting in more instinctual shooting and improved accuracy. The narrow profile makes them perfect for all hand sizes. The black label has a round 4inch barrel. Its barrel is two toned silver/ carbon fiber with a full length picatinny scope base. It also features an under barrel accessory rail with Crimson Trace Rail Master Laser Mounted, shipped in 13″ pistol rug.
