Madbull has released their next generation Metal Bodies and is a perfect addition to their impressive line of high quality upgrade parts. The newest generation metal bodies are CNC machined from aluminum with officially licensed trademarks much like the older version but with new features. The new Madbull metal bodies have been redesigned to fit the needs of today’s airsoft player by having a shortened stock tube so you can run buffer tubes specifically made for lipo batteries. They also feature self retaining pins so the pins never have to leave the body to prevent misplacement or lost during combat. With updated style of upper receiver, it enables increased body security and reduces upper and lower receiver play. Much like the older version, the Madbull Ultimate Hop Up chamber is also included with the body.
