The CM057A is a full sized SVD electric sniper rifle. This gun is fully made of metal and very durable. It is a sniper rifle so it can only fire in semi auto mode. However, since it is electric you do not need to cock it before each shot. This is a big advantage over bolt action, spring powered snipers as you can get more shots on target much faster. A stick type battery and battery charger are included with the gun. The battery is housed in the handguard. To open the battery compartment pull down on the lever on the front end of the compartment. Another feature of this gun is that it has a removeable cheek rest, allowing you to adjust the rifle to your preference. For Dragunov fans this is a must have!
