Black Ops Rhino 4.5 mm is a CO2 airgun capable of firing two types of pellets, being a faithful and fully licensed replica of the Chiappa Rhino revolver.
The airgun is manufactured by the Taiwanese company Wingun, which in cooperation with Chiappa Firearms and BO Manufacture developed an excellent replica distinguished by realistic weight, dimensions, manual operation, and compatibility of the sighting devices with the original firearm.
As a result, a CO2 air revolver was created that features all the characteristic design elements of the Chiappa Rhino:
The revolver features a heavy construction made almost entirely of metal, ensuring reliable and long‑term use. Only the grip panels are made of polymer, faithfully imitating the wooden grip used in firearms. Thanks to this design, the airgun weighs as much as 1100 g, which is almost the same as a loaded revolver. The airgun is equipped with a 5‑inch (127 mm) barrel, ensuring good accuracy even at longer distances. The Black Ops Rhino 4.5 mm uses fiber‑optic sighting devices consisting of a fixed front sight and a rear sight adjustable vertically and horizontally. The realism of the design is emphasized by the fact that the airgun’s sighting devices are compatible with those used on firearms. Just like the original, the airgun features a hexagonal cylinder, a cocked firing‑pin indicator (internal hammer), and a ventilated high‑profile barrel.
Similarly to the original, the grip has a smooth profile, a high beavertail, and textured side panels ensuring a comfortable and secure grip.
The revolver is designed to fire two types of pellets — 4.5 mm diabolo pellets and 4.46 mm BB's. Instead of a classic magazine, brass cartridges resembling firearm ammunition are used for loading. After placing a diabolo pellet or BB in the rear part of the cartridge, the shells are inserted into the cylinder chambers. This functionality makes the airgun ideal for both precision and dynamic shooting. Thanks to this, there is no need to make a difficult choice between a BB airgun and a diabolo pellet airgun.
During shooting, the cylinder rotates automatically, just like in a real revolver. A side lever is used to unlock the cylinder.
The revolver is powered by compressed carbon dioxide supplied from a 12 g CO2 capsule. The fired diabolo pellet reaches an energy of approximately 3.5 J, allowing accurate shooting at distances of up to 30 m. Loading and replacing the CO2 capsule is very simple — just remove the polymer grip panel, place the capsule in the port, and tighten it using an Allen key. The mounting key is permanently attached to the grip panel, so it is always with the airgun, preventing the common problem of forgetting the tool required to replace the capsule.
One capsule allows about 60 shots with consistent muzzle velocity. It should be remembered that the number of shots is mostly affected by air temperature and the shooting pace.
The revolver features an SA/DA trigger mechanism with an internal hammer, which means a shot can be fired by self‑cocking or after manually cocking the hammer. Behind the rear sight there is a firing‑pin cocking indicator informing the shooter that the gun is ready to fire. This solution results from the fact that, unlike classic revolvers, the Chiappa Rhino fires from the lower chamber of the cylinder, while the main hammer is located inside the grip. In this case, the external hammer serves only as a lever used to cock the internal hammer.
