Golden Eagle M-147 Polymer M4 / M16 Airsoft Lower Receiver - BLACK
The new Golden Eagle M-147 Polymer M4 / M16 Lower Receiver is constructed of polymer, making it both lightweight and durable. One great feature about the M4 / AR platform is the interchangeability of both the lower and upper receivers. This means the same lower receiver can be used with a full-length DMR-style or CQB type upper receiver. This interchangeability is great for anyone building their own custom airsoft rifles. The Golden Eagle lower receiver is compatible with most M4 or M16 upper receivers. All you have to do is align both the upper and lower receivers and insert the pins!
