I have recently purchased a used Classic Army SA58. The weapon is one of the nicest airsoft guns I have ever held. The externals are metal and high quality CA plastic. Though I was disappointed by the missing pin to pull back the bolt, the bolt is functional as well as a functional bolt catch. The rate of fire with a 9.6v is better than any of my other guns. I do not have a chronometer so I cannot determine the rate of fire or velocity. I will post an accuracy measurement soon.
