Guns Modify MWS M4 GBB Rifle (URGI with COLT Receiver, Level 2, 14.5 inch)

The URG-I stands for Upper Receiver Group Improved is an improved upper receiver group currently used by many special units in the United States military.  Designed to replace guns like the MK18, the URG-I aims to modernize many of the weapon systems currently in use with lightweight M-LOK rails, an improved charging handle, and an updated barrel. 

The airsoft version as we have here from Guns Modify seems to be very similar to other offerings patterned similarly.  However, while the externals seem to be yet another URG-I rifle, it's the internals that makes this rifle truly shine.  

Internally, the rifle runs on the Tokyo Marui M4 MWS system making it incredibly reliable and consistent, not to mention exceptionally gas efficient.  This also means that the magazines are compatible with other third-party or first-party ones.  

Furthermore, being from Guns Modify, this rifle is already pre-upgraded out of the box as it uses parts from Guns Modify.  However, if you want to further upgrade them, you have access to the wide variety of upgrade parts available to any other MWS user.
