Metal M4/M16 Receiver with Buffer Tube and Quick Spring Change

Original CYMA metal receiver for M4 and M16 series electric airsoft guns. Made of aluminium alloy with a matte black finish. There are no printed logos or markings on the receiver. The buffer tube is attached to the receiver by inserting and twisting it into place using a bayonet-style locking system and is then secured by tightening the nut. Therefore, if the gearbox is equipped with a quick spring change system, the spring can be easily replaced through this receiver.

In addition to the upper and lower receiver, the package also includes:

• Buffer tube spacer
• Retractable stock buffer tube
• Dust cover
• Receiver pins
• Bolt catch
• Magazine catch
• Charging handle
• Fire selector
