This G&P Navy Style body is designed for use with the Marui M4 / M16 series. The package consists of one high quality die-cast metal body, with ejection port cover, metal hop-up set, hop-up rubber, receiver pin set and forward assist knob. Has a Navy Seals Logo, with alternative safety catch markings - "quiet", "solo" and "go loud" (instead of the usual "safe, semi, auto"). Very cool metal body!
The B Type version comes with a shortened rear extension to allow more versatility when it comes to fitting different types of stocks.
