Comments: The GHK M4 RIS GBB VER 2.0 not only has authentic Colt markings but also comes with one of the best gas blowback system in the world, the GHK system.  Its lighter weight magazine design reduces its weight by 35% compared to the old 1st generation magazines making things more maneuverable on field, especially for beginners.  The Metal RIS handguard equally makes the gun more receptive to further upgrades and will allow you to combine a series of 20 mm accessories with the integrated factory sight for a much better performance.  Besides being a hands-down performer, the rifle is also built to last featuring some great internal modifications as well as a top quality build by GHK to become your ultimate workhorse on field.
