One Year Limited Warranty One of the most versatile airguns on the market, the Crosman 2100B multi-pump pneumatic shoots either steel BBs or .177 lead pellets. With 200 BB rounds in the gun's reservoir (17 BBs in the magazine), you'll be shooting for hours without having to reload. Just pump and shoot! If you prefer to shoot pellets, the 2100B can do that, too (loaded one at a time). As both a repeater and a single-shot, this rifle offers adaptability not found in most other airguns. If pest elimination or hunting is your bag, you can take very small rodents (at close distances) with pellets. The 11mm dovetail makes scoping the gun an easy project. Both BBs and pellets can be used to shoot targets, although steel BBs should never be shot at metal targets and objects. Never pump your 2100B more than 10 pumps!
