The Remington AirMaster is a variable pump-action pneumatic air rifle. It will chamber and fire BBs and pellets, though only one of the latter can be chambered at once. You have a gravity-fed 17-round BB magazine, however.
Besides the 17-round magazine, a reservoir holds 200 BBs, and a single action moves the BBs into the magazine.
All furniture on this specific model is black and made of polymer. The barrel shroud is nickel for a bright finish, offering some contrast to an otherwise somber color scheme. You can find some checkering on the pistol grip and pump areas that allow damp fingers to grasp the weapon firmly.
Even though there are iron sights and adjustable rear notch, a 4×15 scope is included with this air rifle. It helps with long-range shooting.
Thanks to the new valve design, the AirMaster 77 can reach 750 FPS with lead pellets and 800 with BBs. You can pump more air for shooting. The maximum number of pumps is 12; you should never go beyond that.
