Using open sights, this gun delivered 10 Crosman Premier pellets (Premiers sold in the cardboard box, not the metal tin) into a 0.539" group at 10 meters. If this gun retailed for $300, that wouldn't surprise anyone...but it's a fraction of that. If you enjoy accuracy combined with variable power, get this gun!
Pump the 2100B from 3 to 10 times, depending on the distance you're shooting. Light in weight, this full-size powerhouse launches pellets up to 725 fps and BBs up to 755 fps.
