The newest model from GBLS is the GDR416, it has all the same training weapon features of the original GDR15, but is based on the iconic HK 416D in short barrel 10.5" flavour.
As with all things GBLS the build quality of GDR416 is nothing but spectacular as you would expect from this training weapon.
The GDR416 has the correct upper and lower receiver, straight mag well and increased height upper receiver with the RIS rail system locking tin to place on the top rail.
The differences between the GDR15 and GDR416 are the following
The GBLS DAS system is hard to describe as it uses a gearbox in the lower receiver which interacts with a full size moving bolt in the upper as you would find in a GBBR platform.
