This is the rare fist model of Ghk ak74 that came with factory steel barrel (the only such ghk other than the RPK). — this one is my baby. Real Russian handguard and muzzle brake. ALL steel as much as it can be. Fully upgraded everywhere. Internals are w&s steel, bolt carrier steel, full travel kit. Aluminum hopup chamber. Double bell launcher is built like a tank. Comes included $150 value. I was gonna wear it down but didn’t get to it. was going for the heavy battle look like in the last two pics. — ask any questions.
