Spring Airsoft Rifles: Like their pistol counterparts, the Spring Airsoft Rifles are life-size replicas of famous military-issued rifles. Like spring pistols, they are very easy to operate and require manual cock back for every single shot. They are a great choice for entry-level Airsoft enthusiasts who are looking for stronger fire-power than that of which the Airsoft Spring Pistols provide. They are also very durable and cost-efficient. These model guns are able to project normal 6mm BB’s, and metallic BB’s. Paintball BB’s are not recommended.
